As a Commercialization Lead at Endurance, you will shape commercial strategy, customer development, and deal execution across the Pacific Ocean, Endurance's target market, from the first power offtake agreements today to the bankable, multi-gigawatt project pipeline that defines the company's long term commercial trajectory.
You will be in the room with utility executives, hyperscaler infrastructure leaders, sovereign energy authorities, and defense program offices, structuring the deals that translate Endurance's technology into committed contracts, capital, and customers. In the near term, that means driving the commercial thread with hyperscaler partners on subsea pilots, structuring offtake and partnership terms for our first commercial projects, leading commercial work on the US federal lease and Program of Record path, and developing the partnership architecture for our Japan and broader Pacific opportunities.

The Controller owns the books at Endurance and builds the machinery that maintains them. You will stand up the accounting function from scratch: the monthly close, GAAP financials, internal controls, ERP, and the multi-entity structure behind our projects. Your mandate is to make Endurance audit-ready from day one and keep it that way as we grow from startup into an owner-operator of power plants around the world.
We are scaling a factory, standing up project entities, and heading into institutional diligence, and none of it works without accounting infrastructure that holds up: a fast and reliable close, clean consolidation across entities, cost accounting that reflects real production, and controls that pass audit. The decisions you make on systems and entity structure this year are ones the company will live with for a decade.
You will report directly to the COO, transitioning to finance leadership as the team grows. You will work directly with executives, auditors, and outside counsel, design the function to run without heroics, and hire the accounting team as the company scales.
Own the monthly close end to end, and drive it to a fast, reliable cadence with clean, GAAP-compliant financial statements.
Lead the implementation and ownership of our ERP (NetSuite or equivalent), including chart of accounts design, integrations, and process automation.
Design and operate internal controls appropriate to our stage, and mature them toward institutional and audit-grade standards.
Own multi-entity accounting and consolidation, including project SPVs and international subsidiaries as they come online, and set the bookkeeping standards for new entities in partnership with counsel.
Own audit readiness: select and manage auditors, run the audit process, and keep the company diligence-ready for lenders and investors.
Build cost and inventory accounting for our manufacturing operation, including standard costs, WIP, and production variances.
Own revenue recognition for first-of-a-kind contracts, including power sales, milestones, and long-term agreements.
Coordinate tax compliance and planning with outside advisors across federal, state, and international jurisdictions.
Own payroll, equity accounting, and stock-based compensation in partnership with People and outside counsel.
Own accounts payable, accounts receivable, and cash management operations, including banking relationships and treasury operations.
Partner with the Head of Finance to connect close-to-forecast, so actuals, budget, and forecast reconcile every month.
Build and lead the accounting team as the company grows, and stand up the systems and processes the function runs on.
~10 years of progressive accounting experience, including controller or assistant controller ownership at a scaling company. We care about what you have built, not where you sat; backgrounds in venture-backed hardware startups, energy or industrial companies, project finance companies, or public accounting followed by industry can all fit.
Track record of building the accounting function at a company that scaled: close, controls, ERP, and policies built from scratch, not inherited.
Deep GAAP fluency, including revenue recognition, inventory and cost accounting, capitalization policy, and stock-based compensation.
Experience owning multi-entity consolidation, ideally including SPVs, joint ventures, or international subsidiaries.
Hands-on experience leading an ERP implementation or migration (NetSuite strongly preferred).
Experience selecting and managing auditors and running annual audits, and owning responses to lender and investor financial diligence.
Experience with cost accounting in a manufacturing or hardware environment, including inventory, WIP, and standard costing.
Detail-oriented and organized manager who can own the close calendar, documentation, and management of outside advisors, auditors, and service vendors.
Clear, direct writing suitable for accounting memos, policy documentation, and audit and diligence responses.
Excellent communication skills, able to code switch across audiences: auditors, engineers, executives, and finance professionals.
Comfort operating with ambiguity, incomplete data, and short timelines.
CPA.
Experience at an energy, infrastructure, or project finance company, including project-level and SPV accounting.
Familiarity with project financing structures and the accounting they require: intercompany agreements, waterfall distributions, and lender reporting.
Experience with equity accounting at a venture-backed startup, including 409A cycles and cap table systems.
Prior experience standing up accounting for international subsidiaries or foreign-flag entities.
Exposure to IPO readiness, SOX, or public-company controls standards.
Experience with government contracts or grant accounting.
Experience operating in high-urgency organizations with aggressive commercial and operational.

Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.
As a Senior/Principal Software Engineer at Endurance, you will build the software stack, controls, UIs, and simulation infrastructure that allows our engineering team to rapidly build and validate every component and every subsystem that goes into a subsea geothermal power plant.
As we scale from our first hundred-kilowatt subsea demonstration to gigawatt deployments, the size and complexity of our test and production infrastructure will rise exponentially, rivaling the complexity of the power plants themselves. We believe an internal software team building the right stack from scratch is one of the highest-leverage moves we can make as we scale. Every improvement you make increases the speed at which mechanical, electrical, firmware, and controls engineers can design, test, iterate, and deploy hardware. Your job is to build the software ecosystem that enables that acceleration.
This role can span the entire software and hardware stack. You will work directly with electrical, mechanical, and test engineers to understand what they are building, identify how it should be tested, and rapidly create the infrastructure needed to answer critical engineering questions.
One day you will be writing bare-metal and Linux firmware interfacing with custom PCBs, large-scale industrial equipment, and next-gen Endurance power plants. The next you will be closely embedding with engineers to build data acquisition and visualization systems that allow engineers to understand and control plants in real time, and the first generation of Endurance’s unified testing platform. Beyond that you will be building a high-performance simulation stack to simulate our power plants and developing hardware-in-the-loop environments to test real operating conditions and failure modes.
As we scale, you will own the software stack to automate large-scale production lines for Endurance’s power plants, with the goal of a lights-out fully-automated factory.
The ideal candidate is an exceptional software engineer who enjoys working up and down the stack, from firmware to web UIs. You should be equally comfortable designing foundational software architecture, writing software for non-technical users, and debugging software with hardware in the loop. You be a part of Endurance’s software team and support firmware/full stack/controls projects across the company.
You will be the first software engineer focused on test and automation infrastructure at the company. You will work directly with the founding team and engineering leadership across Endurance, and as the function grows, you will have significant influence on the company’s software architecture, engineering standards, and future hires.
Design and build the software ecosystem that powers testing across Endurance, from component qualification through full integrated system validation.
Architect and implement hardware-in-the-loop (HITL) and simulation environments that allow firmware and controls software to be tested under realistic operating conditions and failure scenarios.
Develop software for automated test execution, operator interfaces, data acquisition, visualization, storage, and analysis.
Design and integrate the electrical and controls infrastructure behind new test systems, including Endurance-designed PCBs, DAQs, PLCs, VFDs, sensors, instrumentation, and industrial communication networks.
Partner closely with firmware, electrical, mechanical, controls, and systems engineers to rapidly develop new testing capabilities.
Build scrappy one-off test systems when speed matters, then evolve successful concepts into scalable engineering infrastructure.
Write production-quality software while establishing the architecture and engineering patterns that future test systems will build upon.
Own the technical foundation of Endurance’s testing ecosystem as it grows from individual laboratory experiments to full power plant validation.
Collaborate with other members of the software team to support software projects across the company.
Help shape the test infrastructure organization as it grows, including interviewing and onboarding future engineers.
5+ years of software engineering experience.
Strong software engineering skills in Python, Rust, C++, C, or similar languages.
Demonstrated ability to ship production software end-to-end, from architecture through deployment and operation.
Track record building software for hardware systems, including automated testing, hardware-in-the-loop (HITL), industrial controls, robotics, aerospace, automotive, or other complex electromechanical products.
Technical fluency strong enough to hold credibility with mechanical, electrical, firmware, and systems engineers.
Ability to work onsite in Seattle and travel to deployment sites as required.

","descriptionPlain":"ABOUT ENDURANCE\n\nEndurance is building the world's first modular subsea geothermal power plants, converting vast thermal resources under the ocean into gigawatts of baseload power. Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.\n\n\nWHAT YOU'LL BE DOING\n\nAs a Senior/Principal Software Engineer at Endurance, you will build the software stack, controls, UIs, and simulation infrastructure that allows our engineering team to rapidly build and validate every component and every subsystem that goes into a subsea geothermal power plant.\n\n \n\nAs we scale from our first hundred-kilowatt subsea demonstration to gigawatt deployments, the size and complexity of our test and production infrastructure will rise exponentially, rivaling the complexity of the power plants themselves. We believe an internal software team building the right stack from scratch is one of the highest-leverage moves we can make as we scale. Every improvement you make increases the speed at which mechanical, electrical, firmware, and controls engineers can design, test, iterate, and deploy hardware. Your job is to build the software ecosystem that enables that acceleration.\n\n \n\nThis role can span the entire software and hardware stack. You will work directly with electrical, mechanical, and test engineers to understand what they are building, identify how it should be tested, and rapidly create the infrastructure needed to answer critical engineering questions.\n\n \n\nOne day you will be writing bare-metal and Linux firmware interfacing with custom PCBs, large-scale industrial equipment, and next-gen Endurance power plants. The next you will be closely embedding with engineers to build data acquisition and visualization systems that allow engineers to understand and control plants in real time, and the first generation of Endurance’s unified testing platform. Beyond that you will be building a high-performance simulation stack to simulate our power plants and developing hardware-in-the-loop environments to test real operating conditions and failure modes.\n\n \n\nAs we scale, you will own the software stack to automate large-scale production lines for Endurance’s power plants, with the goal of a lights-out fully-automated factory.\n\n \n\nThe ideal candidate is an exceptional software engineer who enjoys working up and down the stack, from firmware to web UIs. You should be equally comfortable designing foundational software architecture, writing software for non-technical users, and debugging software with hardware in the loop. You be a part of Endurance’s software team and support firmware/full stack/controls projects across the company.\n\n \n\nYou will be the first software engineer focused on test and automation infrastructure at the company. You will work directly with the founding team and engineering leadership across Endurance, and as the function grows, you will have significant influence on the company’s software architecture, engineering standards, and future hires.\n\n \n\n\nKEY RESPONSIBILITIES\n\n - Design and build the software ecosystem that powers testing across Endurance, from component qualification through full integrated system validation.\n\n - Architect and implement hardware-in-the-loop (HITL) and simulation environments that allow firmware and controls software to be tested under realistic operating conditions and failure scenarios.\n\n - Develop software for automated test execution, operator interfaces, data acquisition, visualization, storage, and analysis.\n\n - Design and integrate the electrical and controls infrastructure behind new test systems, including Endurance-designed PCBs, DAQs, PLCs, VFDs, sensors, instrumentation, and industrial communication networks.\n\n - Partner closely with firmware, electrical, mechanical, controls, and systems engineers to rapidly develop new testing capabilities.\n\n - Build scrappy one-off test systems when speed matters, then evolve successful concepts into scalable engineering infrastructure.\n\n - Write production-quality software while establishing the architecture and engineering patterns that future test systems will build upon.\n\n - Own the technical foundation of Endurance’s testing ecosystem as it grows from individual laboratory experiments to full power plant validation.\n\n - Collaborate with other members of the software team to support software projects across the company.\n\n - Help shape the test infrastructure organization as it grows, including interviewing and onboarding future engineers.\n\n \n\n\nREQUIRED QUALIFICATIONS\n\n - 5+ years of software engineering experience.\n\n - Strong software engineering skills in Python, Rust, C++, C, or similar languages.\n\n - Demonstrated ability to ship production software end-to-end, from architecture through deployment and operation.\n\n - Track record building software for hardware systems, including automated testing, hardware-in-the-loop (HITL), industrial controls, robotics, aerospace, automotive, or other complex electromechanical products.\n\n - Technical fluency strong enough to hold credibility with mechanical, electrical, firmware, and systems engineers.\n\n - Ability to work onsite in Seattle and travel to deployment sites as required.\n\n \n \n\n\nPREFERRED QUALIFICATIONS\n\n - Familiarity with Rust and Nix.\n\n - Experience building hardware-in-the-loop (HITL) or software-in-the-loop (SITL) environments.\n\n - Experience developing simulation or emulation software for embedded or controls applications.\n\n - Experience with industrial automation platforms including PLCs, DAQs, VFDs, National Instruments, Beckhoff, Siemens, or similar systems.\n\n - Familiarity with industrial communication protocols such as EtherCAT, CAN, Modbus, or OPC UA.\n\n - Experience designing data acquisition and telemetry systems for hardware development.\n\n - Background in aerospace, robotics, automotive, energy, defense, or other fast-paced hardware industries.\n\n - Comfort working hands-on in the lab, including wiring sensors, debugging electrical systems, integrating instrumentation, and bringing up new test hardware.\n\n - Experience building internal engineering infrastructure that enables other engineers to move faster.\n\n \n\n\nCOMPENSATION, BENEFITS, & PERKS\n\nAs a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees.

We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.
As a Senior Electrical Test Engineer at Endurance, you will own the test systems for our subsea electronics: the racks, fixtures, interface harnesses, automation software, and procedures we use to develop, qualify, and accept every subsea electrical system we build.
This is a design-ownership role. You will partner with subsystem design engineers, reviewing ICDs, requirements, and designs to determine the best approach to validating them across an array of environmental conditions, including temperature, extreme pressure, and accelerated stress testing.
Once deployed, our hardware cannot be serviced. The tests you design and execute are the best chance we have to find problems while they are still easy to fix. Your judgment about what to test, and how rigorously, will directly determine whether our systems run reliably on the seafloor.
Own the hardware test systems for Endurance's subsea electronics end to end: requirements, architecture, design, build, bring-up, documentation, and upkeep
Work with each subsystem's electrical RE from the start of development, derive test requirements from their design and interface documents, and provide design-for-test feedback
Design and build test racks, unit-under-test (UUT) fixtures, and interface and breakout harnesses that connect UUTs to power, loads, instrumentation, and data acquisition, including through pressure-vessel bulkheads and penetrators
Write automated test software for instrument control, data acquisition, sequencing, limit checking, and report generation
Plan and run development, qualification, and acceptance test campaigns: functional and power tests, hipot and insulation resistance, thermal, and pressure testing in hyperbaric chambers
Write test plans and procedures, set pass/fail criteria with the RE, execute the tests, and author test reports
Troubleshoot failures to the component level, separate test-system faults from UUT faults, and drive root cause and corrective action
Build test capability that scales from one-off development units to production acceptance test of commercial systems, improving coverage, cycle time, and operator usability as we grow
Help define Endurance's test standards, lab infrastructure, and test-equipment supplier base
Bachelor's degree in electrical engineering or a related STEM discipline
3+ years of experience in hardware or electronics test engineering, instrumentation, or data acquisition system design for complex hardware
Hands-on experience designing, building, and bringing up electronics test systems: racks, fixtures, interface harnesses, DAQ, power supplies, and electronic loads
Fluency with electrical lab equipment, including oscilloscopes, DMMs, programmable power supplies, electronic loads, and source measure units
Working knowledge of common hardware interfaces: CAN, RS-422/485, Ethernet, SPI, I2C, and analog signal conditioning and conversion
Ability to read schematics and debug electronics at the board and component level
Experience writing test plans, procedures, and reports, and defining pass/fail criteria with design engineers
Strong communication skills and the ability to work closely with electrical engineers, mechanical engineers, and technicians
Comfortable in a fast-paced, prototype-driven environment where designs evolve rapidly, including extended hours during critical test campaigns
Ability to work onsite in Seattle and travel to deployment sites as required
Experience writing software for test automation
Experience testing hardware for subsea, marine, aerospace, or defense systems
Experience with environmental qualification testing: pressure/hyperbaric, thermal, vibration, and shock
Experience with high-voltage and high-power electronics test, including safety interlocks, hipot, and insulation resistance
Experience with hardware-in-the-loop (HIL) test and simulation of subsystem interfaces
Experience with PLCs or industrial control hardware for test-cell automation and safety
Understanding of metrology, measurement uncertainty, and calibration practice
Proficiency writing software in Rust or Python
As a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees. Final base salary will be determined by an array of factors including internal equity, job-related knowledge, skills, and work experience.
A key aspect of our compensation philosophy is that value creation should be aligned with rewards. Right now this means equity is a significant portion of every full-time employee's compensation. As the company matures, there will be continued evolution and changes to the total rewards and total compensation package. What will always be true is that if we win, we win together. Equity is granted to every full-time employee as a meaningful piece of ownership. We believe the people building the company should share directly in the value they create.
In addition to a competitive base salary and equity, employees will receive all of our other great benefits and perks, including:

Time Away: Flexible PTO including 12 paid company holidays
Global Fieldwork: Travel to fascinating deployment sites along oceanic ridges in locations like the Pacific Northwest, Hawaii, Iceland, Japan, New Zealand, and the Azores
Hands-on Experience: Participate in sea trials and deployment operations in partnership with leading oceanographic institutions
Cutting-edge Development: Work with technology that spans high-power electronics, marine systems, and clean energy
Impactful Work: Help solve one of the world's most pressing challenges
Dive Certification: Company-sponsored recreational dive certification
Other Perks: Access to the company boat, free meals and snacks, and the list goes on!

Run corporate governance and entity management for the parent company and its project companies, in the US and abroad
Work with External Affairs and outside counsel on federal offshore leasing, project company formation, and international project agreements
Stand up our compliance programs for export controls (EAR/ITAR), sanctions screening, and anti-corruption (FCPA) ahead of international project agreements
Advise our People team on employment matters: offer letters, contractor and consulting agreements, the handbook and policies, separations, and multi-state and international hiring
Manage our IP portfolio with outside counsel, including trademarks, patent strategy, and IP terms in commercial and supply agreements
Review real estate leases, insurance programs, and vendor agreements as we scale our facilities
Train the team on what they can sign, when to bring in legal, and how to spot issues early
Qualifications
Active bar membership in good standing in at least one US state, and eligible to register as in-house counsel in Washington
8+ years of directly applicable experience
Extensive experience drafting and directly negotiating complex commercial agreements
Experience in energy, infrastructure, industrial, or hardware businesses
Proven ability to manage outside counsel to a budget, including scoping matters and negotiating fees
Generalist range across commercial, corporate, employment, and compliance work
Clear communication that a busy engineer or executive can action on
High ownership mindset and comfort operating without support staff like a paralegal
Track record of working effectively in fast-paced environments where business needs change quickly
Able to work on-site at our Seattle headquarters, with occasional travel to project sites and counterparties
Preferred Skills
Experience with power purchase agreements, offtake, or project development, especially in offshore wind, geothermal, or other first-of-a-kind energy
Project finance experience for energy or major industrial projects
Experience within a law firm as well as an operating company as their first or second in-house lawyer
International commercial experience, especially in Asia-Pacific or with development finance institutions
Experience building export control (EAR/ITAR), sanctions, or FCPA compliance programs
Venture-backed corporate experience: equity financings, venture debt, board governance, and equity administration
Maritime and offshore agreements, such as vessel charters, equipment purchases, and marine insurance
Federal offshore leasing (BOEM) or government contracting experience
Experience building contract management systems and self-serve templates for a growing team

Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.
The Role
Every watt the plant produces passes through electromechanical hardware. The power electronics live on the seafloor, so they are packaged in pressure-compensated, fluid-filled housings, cooled by seawater, and connected to the rest of the plant through high-power busswork and wet-mate and dry-mate connectors we design in-house. Every valve the plant actuates and every mechanism that moves is driven by subsea actuators and motors. We design, build, test, and deploy all of it. In this role you will focus on the hardware where electricity, fluid, and pressure meet: electronics cooling and thermal management; subsea packaging of high-power electronics, including dielectric fluids, compensation, penetrators, and feedthroughs; high-power busswork and electrical interfaces; wet-mate and dry-mate connectors; and actuators, motors, pumps, and mechanisms with their dynamic seals and magnetic couplings. You will share that scope with a few other engineers, and specific hardware will be yours end to end. You will work most closely with our power electronics engineers.
Your First Year
Help deliver the electromechanical hardware for our first commercial system, the first subsea geothermal plant to put power on a grid: the cooled, pressure-compensated electronics packaging, the busswork and connectors that carry its power, and the actuators that run it, all designed, built, qualified, and operating on the seafloor.
How We Work
Our mechanical engineering team is a small group of senior and principal engineers who split the plant's hardware between them. Each engineer owns their hardware end to end: requirements, design, drawings, build, test, and deployment. Principal engineers own the plant architecture, and you will be part of those decisions. We are looking for people who have built hardware, debugged it in the lab or the field, and want to own the result.
Responsibilities
• Own specific electromechanical hardware end to end: electronics cooling and enclosures, busswork and connectors, or actuators and mechanisms
• Design high-power electrical interfaces: busswork, wet-mate and dry-mate connectors, contact and insulator design, dielectric sealing, and mate and demate mechanics
• Design subsea packaging for high-power electronics: fluid-filled and pressure-compensated enclosures, dielectric fluid selection, penetrators, and feedthroughs
• Design electronics cooling and thermal management: heat rejection from converter stacks through the enclosure to seawater, cold plates, and immersion cooling
• Design subsea actuators, motors, pumps, and mechanisms: dynamic and rotating seals, magnetic couplings, position feedback, and fail-safe behavior
• Translate electrical requirements (voltage, current, creepage, thermal) into mechanical designs, working day to day with the power electronics engineers
• Design and build test setups for high voltage under hydrostatic pressure, insulation resistance, partial discharge, thermal performance, and long-duration immersion
• Lead root-cause investigations on connector, enclosure, and actuator failures and implement corrective actions
• Define interfaces with the valves and primary structures owned by your peers
• Work directly with machine shops, molders, and specialty suppliers on contacts, insulators, seals, and precision mechanisms
• Contribute to plant-level electrical architecture and packaging decisions alongside our principal engineers
• Create detailed 3D CAD models, drawings, and tolerance stacks for electromechanical assemblies
Basic Qualifications
• Bachelor's degree in mechanical engineering, electrical engineering, or a related engineering discipline
• 6+ years of professional experience designing electromechanical hardware (connectors, actuators, mechanisms, or electronics packaging) for demanding environments
• Ownership of at least one electromechanical component from concept through qualification and fielded use
Preferred Skills and Experience
• Experience designing subsea electrical connectors, penetrators, busswork, or actuators, or equivalent experience with spacecraft mechanisms, downhole tools, or power electronics packaging for aerospace or automotive
• Hands-on experience with dielectric fluids, pressure compensation, and sealing high voltage against seawater
• Experience with dynamic and rotating seals, magnetic couplings, and the failure modes of mechanisms in long-duration service
• Experience with thermal management of power electronics, including liquid- or immersion- cooled systems
• Working knowledge of high-voltage design and test: creepage and clearance, insulation resistance, partial discharge
• Experience sizing motors and actuators and integrating electronics into mechanical assemblies
• Experience at a small or fast-moving hardware organization, where you had to make good engineering decisions with incomplete information and limited resources
• A track record of taking on increasing responsibility and delivering something difficult early in your career
• Experience on an engineering competition team (Formula SAE, Baja SAE, RoboSub, rocketry, or similar) or an equivalent self-directed hardware project

","descriptionPlain":"ABOUT ENDURANCE\n\nEndurance is building the world's first modular subsea geothermal power plants, converting vast thermal resources under the ocean into gigawatts of baseload power. Backed by Founders Fund, Felicis, First Round Capital, and Point72 Ventures, our founding team includes veterans from SpaceX, Helion, Blue Origin, and Apple. We have completed multiple deep-ocean deployments to subsea volcanoes and are launching a long-term demonstration project this fall. By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.\n\nThe Role\n\nEvery watt the plant produces passes through electromechanical hardware. The power electronics live on the seafloor, so they are packaged in pressure-compensated, fluid-filled housings, cooled by seawater, and connected to the rest of the plant through high-power busswork and wet-mate and dry-mate connectors we design in-house. Every valve the plant actuates and every mechanism that moves is driven by subsea actuators and motors. We design, build, test, and deploy all of it. In this role you will focus on the hardware where electricity, fluid, and pressure meet: electronics cooling and thermal management; subsea packaging of high-power electronics, including dielectric fluids, compensation, penetrators, and feedthroughs; high-power busswork and electrical interfaces; wet-mate and dry-mate connectors; and actuators, motors, pumps, and mechanisms with their dynamic seals and magnetic couplings. You will share that scope with a few other engineers, and specific hardware will be yours end to end. You will work most closely with our power electronics engineers.\n\nYour First Year\n\nHelp deliver the electromechanical hardware for our first commercial system, the first subsea geothermal plant to put power on a grid: the cooled, pressure-compensated electronics packaging, the busswork and connectors that carry its power, and the actuators that run it, all designed, built, qualified, and operating on the seafloor.\n\nHow We Work\n\nOur mechanical engineering team is a small group of senior and principal engineers who split the plant's hardware between them. Each engineer owns their hardware end to end: requirements, design, drawings, build, test, and deployment. Principal engineers own the plant architecture, and you will be part of those decisions. We are looking for people who have built hardware, debugged it in the lab or the field, and want to own the result.\n\nResponsibilities\n\n• Own specific electromechanical hardware end to end: electronics cooling and enclosures, busswork and connectors, or actuators and mechanisms\n\n• Design high-power electrical interfaces: busswork, wet-mate and dry-mate connectors, contact and insulator design, dielectric sealing, and mate and demate mechanics\n\n• Design subsea packaging for high-power electronics: fluid-filled and pressure-compensated enclosures, dielectric fluid selection, penetrators, and feedthroughs\n\n• Design electronics cooling and thermal management: heat rejection from converter stacks through the enclosure to seawater, cold plates, and immersion cooling\n\n• Design subsea actuators, motors, pumps, and mechanisms: dynamic and rotating seals, magnetic couplings, position feedback, and fail-safe behavior\n\n• Translate electrical requirements (voltage, current, creepage, thermal) into mechanical designs, working day to day with the power electronics engineers\n\n• Design and build test setups for high voltage under hydrostatic pressure, insulation resistance, partial discharge, thermal performance, and long-duration immersion\n\n• Lead root-cause investigations on connector, enclosure, and actuator failures and implement corrective actions\n\n• Define interfaces with the valves and primary structures owned by your peers\n\n• Work directly with machine shops, molders, and specialty suppliers on contacts, insulators, seals, and precision mechanisms\n\n• Contribute to plant-level electrical architecture and packaging decisions alongside our principal engineers\n\n• Create detailed 3D CAD models, drawings, and tolerance stacks for electromechanical assemblies\n\nBasic Qualifications\n\n• Bachelor's degree in mechanical engineering, electrical engineering, or a related engineering discipline\n\n• 6+ years of professional experience designing electromechanical hardware (connectors, actuators, mechanisms, or electronics packaging) for demanding environments\n\n• Ownership of at least one electromechanical component from concept through qualification and fielded use\n\nPreferred Skills and Experience\n\n• Experience designing subsea electrical connectors, penetrators, busswork, or actuators, or equivalent experience with spacecraft mechanisms, downhole tools, or power electronics packaging for aerospace or automotive\n\n• Hands-on experience with dielectric fluids, pressure compensation, and sealing high voltage against seawater\n\n• Experience with dynamic and rotating seals, magnetic couplings, and the failure modes of mechanisms in long-duration service\n\n• Experience with thermal management of power electronics, including liquid- or immersion- cooled systems\n\n• Working knowledge of high-voltage design and test: creepage and clearance, insulation resistance, partial discharge\n\n• Experience sizing motors and actuators and integrating electronics into mechanical assemblies\n\n• Experience at a small or fast-moving hardware organization, where you had to make good engineering decisions with incomplete information and limited resources\n\n• A track record of taking on increasing responsibility and delivering something difficult early in your career\n\n• Experience on an engineering competition team (Formula SAE, Baja SAE, RoboSub, rocketry, or similar) or an equivalent self-directed hardware project\n\n\nCOMPENSATION, BENEFITS, & PERKS\n\nAs a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees.

By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.
The Role
The primary structure is the plant. It carries the hot loop, the power electronics, and the connection to the well; it survives the lift, the splash zone, the transit, and the landing on an active hydrothermal field 1-3 km down; and then it stays there for years in seawater at 100-300 bar. We design, build, test, and deploy it.
In this role you will focus on the plant's load-bearing hardware: frames and skids, foundations and seafloor landing systems, lifting and deployment hardware, mooring and anchoring interfaces, and the pressure housings and pressure-tolerant structures that mount to the frame. You will share that scope with a few other engineers, and specific structures will be yours end to end. We avoid pressure vessels where we can through compensated and pressure-tolerant design, but where we cannot, you will design and analyze them. We use ASME, DNV, and API as references and build our own qualification basis through test.
Your First Year
Help deliver the primary structure for our first commercial system, the first subsea geothermal plant to put power on a grid: designed, analyzed, built, qualified, lifted, and landed on the seafloor. The load cases and qualification basis you help establish carry forward to every plant that follows.
How We Work
Our mechanical engineering team is a small group of senior and principal engineers who split the plant's hardware between them. Each engineer owns their hardware end to end: requirements, design, drawings, build, test, and deployment. Principal engineers own the plant architecture, and you will be part of those decisions. We are looking for people who have built hardware, debugged it in the lab or the field, and want to own the result.
Responsibilities
• Own specific elements of the primary structure end to end: frames, foundations and landing systems, lifting and deployment hardware, or pressure housings
• Define structural load cases from first principles: lift through the splash zone, transit, landing on irregular seafloor, thermal expansion of the hot loop, hydrodynamic loads, and long-duration fatigue and corrosion
• Size structures with hand calculations, then prove them with FEA: static, fatigue, buckling, external-pressure collapse, and thermal
• Design pressure-tolerant and pressure-compensated structures where possible; design and analyze pressure housings where required
• Design lifting, rigging, deployment, and recovery hardware and the interfaces to vessels, cranes, and ROVs
• Select materials and corrosion strategies for multi-year seawater exposure: cathodic protection, coatings, galvanic isolation, titanium, duplex stainless, and composites
• Own weld design and fabrication for your structures and work directly with fabricators on procedures, inspection, and tolerances
• Build and test development articles, then qualify full structures: hydrostatic, external-pressure, fatigue, and thermal cycling
• Lead root-cause investigations on structural and housing failures and implement corrective actions
• Define interfaces with the fluid components, electromechanical hardware, and well connection owned by your peers
• Contribute to plant-level architecture decisions alongside our principal engineers
• Create detailed 3D CAD models, drawings, and tolerance stacks for large assemblies
Basic Qualifications
• Bachelor's degree in mechanical, aerospace, structural, or ocean engineering, or a related engineering discipline
• 6+ years of professional experience designing and analyzing load-bearing structures for
demanding environments
• Ownership of at least one large structure from design through fabrication and fielded use
Preferred Skills and Experience
• Experience designing primary structures for subsea or offshore systems, submarines or naval vessels, launch vehicles or aircraft, or heavy industrial equipment
• Experience designing or analyzing pressure vessels, especially for external pressure, and
familiarity with ASME VIII, DNV, or API
• Strong fundamentals in solid mechanics, structural dynamics, and fatigue; comfortable sizing a structure by hand before confirming it with FEA
• Fabrication fluency: weld joint design, allowables, NDT and inspection, and tolerancing of large weldments
• Experience designing lifting and rigging hardware or working with marine operations
• Experience building test articles and running structural qualification tests
• Experience at a small or fast-moving hardware organization, where you had to make good
engineering decisions with incomplete information and limited resources
• A track record of taking on increasing responsibility and delivering something difficult early in your career
• Experience on an engineering competition team (Formula SAE, Baja SAE, RoboSub, rocketry, or similar) or an equivalent self-directed hardware project
As a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees. Final base salary will be determined by an array of factors including internal equity, job-related knowledge, skills, and work experience.

By leveraging modular design, manufacturing scale, efficient drilling, and latent cooling on the seafloor, we are pioneering a new category of energy that outperforms traditional sources on environmental impact, deployment speed, and cost.
The Role
Our seafloor power plants move 250-350 °C geothermal fluid through a closed loop 1-3 km underwater, surrounded by near-freezing seawater at 100-300 bar. Every valve, seal, fitting, compensator, and filter in that loop has to hold hot, corrosive, scaling fluid on one side and the deep ocean on the other, for years, with no one able to service it. Nobody makes these parts off the shelf. We design, build, test, and deploy them.
In this role you will focus on the fluid components of the plant: isolation, check, control, and relief valves; seats and seals; fittings, manifolds, and compensators; filters and strainers. You will share that scope with a few other engineers, and specific components will be yours end to end. Most of the work is clean-sheet design. You will size seats and springs, choose materials that survive chlorides, sulfides, and silica scaling at temperature, and build the hot-fluid test rigs that qualify your hardware. This is a natural fit for someone who has designed propulsion valves and wants to apply that experience to a hotter fluid, a higher ambient pressure, and a much longer mission.
Your First Year
Help deliver the fluid-component set for our first commercial system, the first subsea geothermal plant to put power on a grid: designed, built, qualified in our own test cells, and operating on the seafloor. The components you own become the baseline for the plants that follow.

• Design valves (isolation, check, control, relief) and sealing systems for 250-350 °C fluid with 100-300 bar external seawater pressure
• Select and qualify materials for hot chloride, sulfide, and silica-scaling environments: nickel alloys, duplex stainless steels, titanium, coatings, and hardfacing
• Perform first-principles flow, thermal, and structural analysis: seat loads at temperature, thermal growth and tolerance stacks, pressure-boundary margins, and fatigue
• Design and build hot-fluid test rigs; run pressure, endurance, leak, thermal-cycling, and corrosion tests to qualify components
• Lead root-cause investigations on test and field hardware and implement corrective actions
• Define interfaces with the actuators and pressure boundaries owned by your peers
• Work directly with machine shops and specialty suppliers on tight-tolerance parts in exotic alloys
• Contribute to plant-level fluid-system architecture decisions alongside our principal engineers
• Create detailed 3D CAD models, drawings, and tolerance stacks
Basic Qualifications
• Bachelor's degree in mechanical engineering, aerospace engineering, or a related engineering discipline
• 6+ years of professional experience designing, testing, or manufacturing fluid-control hardware (valves, regulators, seals, pumps, or similar) for demanding environments
• Ownership of at least one fluid component from concept through qualification and fielded use
Preferred Skills and Experience
• Experience designing propulsion valves or flow-control devices for rocket engines or feed systems (cryogenic, hot-gas, or high-pressure)
• Equivalent depth in subsea oil & gas components (trees, chokes, API 17D/6A), high- temperature steam or geothermal hardware, or nuclear-grade pressure-boundary components
• Strong understanding of seal and seat design, leakage physics, and seal behavior across large temperature ranges
• Strong fundamentals in solid mechanics, fluid dynamics, heat transfer, and materials; comfortable with hand calculations and FEA
• Experience designing and running qualification and acceptance tests and analyzing the results
• Hands-on experience with GD&T, design for manufacture in hard-to-machine alloys, and time in a machine shop and test cell
• Experience at a small or fast-moving hardware organization, where you had to make good engineering decisions with incomplete information and limited resources

Each engineer owns their hardware end to end: requirements, design, drawings, build, test, and deployment. Principal engineers own the plant architecture, and you will be part of those decisions. We are looking for people who have built hardware, debugged it in the lab or the field, and want to own the result.\n\nResponsibilities\n\n• Own specific fluid components in the working-fluid loop from requirements through design, qualification, and field performance\n\n• Design valves (isolation, check, control, relief) and sealing systems for 250-350 °C fluid with 100-300 bar external seawater pressure\n\n• Select and qualify materials for hot chloride, sulfide, and silica-scaling environments: nickel alloys, duplex stainless steels, titanium, coatings, and hardfacing\n\n• Perform first-principles flow, thermal, and structural analysis: seat loads at temperature, thermal growth and tolerance stacks, pressure-boundary margins, and fatigue\n\n• Design and build hot-fluid test rigs; run pressure, endurance, leak, thermal-cycling, and corrosion tests to qualify components\n\n• Lead root-cause investigations on test and field hardware and implement corrective actions\n\n• Define interfaces with the actuators and pressure boundaries owned by your peers\n\n• Work directly with machine shops and specialty suppliers on tight-tolerance parts in exotic alloys\n\n• Contribute to plant-level fluid-system architecture decisions alongside our principal engineers\n\n• Create detailed 3D CAD models, drawings, and tolerance stacks\n\nBasic Qualifications\n\n• Bachelor's degree in mechanical engineering, aerospace engineering, or a related engineering discipline\n\n• 6+ years of professional experience designing, testing, or manufacturing fluid-control hardware (valves, regulators, seals, pumps, or similar) for demanding environments\n\n• Ownership of at least one fluid component from concept through qualification and fielded use\n\nPreferred Skills and Experience\n\n• Experience designing propulsion valves or flow-control devices for rocket engines or feed systems (cryogenic, hot-gas, or high-pressure)\n\n• Equivalent depth in subsea oil & gas components (trees, chokes, API 17D/6A), high- temperature steam or geothermal hardware, or nuclear-grade pressure-boundary components\n\n• Strong understanding of seal and seat design, leakage physics, and seal behavior across large temperature ranges\n\n• Strong fundamentals in solid mechanics, fluid dynamics, heat transfer, and materials; comfortable with hand calculations and FEA\n\n• Experience designing and running qualification and acceptance tests and analyzing the results\n\n• Hands-on experience with GD&T, design for manufacture in hard-to-machine alloys, and time in a machine shop and test cell\n\n• Experience at a small or fast-moving hardware organization, where you had to make good engineering decisions with incomplete information and limited resources\n\n• A track record of taking on increasing responsibility and delivering something difficult early in your career\n\n• Experience on an engineering competition team (Formula SAE, Baja SAE, RoboSub, rocketry, or similar) or an equivalent self-directed hardware project\n\n\nCOMPENSATION, BENEFITS, & PERKS\n\nAs a pre-revenue startup, Endurance Energy offers competitive base salaries and generous equity packages for full-time employees. Final base salary will be determined by an array of factors including internal equity, job-related knowledge, skills, and work experience.\n\nA key aspect of our compensation philosophy is that value creation should be aligned with rewards. Right now this means equity is a significant portion of every full-time employee's compensation. As the company matures, there will be continued evolution and changes to the total rewards and total compensation package. What will always be true is that if we win, we win together. Equity is granted to every full-time employee as a meaningful piece of ownership. We believe the people building the company should share directly in the value they create.\n\nIn addition to a competitive base salary and equity, employees will receive all of our other great benefits and perks, including:\n\n - Benefits: Health, Dental, and Vision insurance coverage\n\n - Time Away: Flexible PTO including 12 paid company holidays\n\n - Global Fieldwork: Travel to fascinating deployment sites along oceanic ridges in locations like the Pacific Northwest, Hawaii, Iceland, Japan, New Zealand, and the Azores\n\n - Hands-on Experience: Participate in sea trials and deployment operations in partnership with leading oceanographic institutions\n\n - Cutting-edge Development: Work with technology that spans high-power electronics, marine systems, and clean energy\n\n - Impactful Work: Help solve one of the world's most pressing challenges\n\n - Dive Certification: Company-sponsored recreational dive certification\n\n - Other Perks: Access to the company boat, free meals and snacks, and the list goes on!\n\nIf you’re selected for consideration, a recruiter will be able to discuss in greater detail.","compensation":{"compensationTierSummary":"$170K – $230K • Offers Equity","scrapeableCompensationSalarySummary":"$170K - $230K","compensationTiers":[{"id":"a5ca454c-babe-469f-8fc5-e640cd3d0799","tierSummary":"$170K – $230K • Offers Equity","title":null,"additionalInformation":null,"components":[{"id":"77f63d1b-4167-4f09-9512-9155c9cff1d6","summary":"$170K – $230K","compensationType":"Salary","interval":"1 YEAR","currencyCode":"USD","minValue":170000,"maxValue":230000},{"id":"fa5bc23a-bae1-4e41-9702-99b1cb1366e5","summary":"Offers Equity","compensationType":"EquityCashValue","interval":"1 YEAR","currencyCode":"USD","minValue":null,"maxValue":null}]}],"summaryComponents":[{"compensationType":"Salary","interval":"1 YEAR","currencyCode":"USD","minValue":170000,"maxValue":230000},{"compensationType":"EquityCashValue","interval":"1 YEAR","currencyCode":"USD","minValue":null,"maxValue":null}]}}],"apiVersion":"1"}
