We are seeking an experienced Staff Electrochemical Systems Architect who will lead the architecture, integration, and performance definition of our metal-fueled power generation platform - from top-level system concept down to individual component and assembly specifications. Across a range of chemical, mechanical, and electrical subsystems, this role will use high-level product requirements to guide technical decisions that define subsystems, interfaces, and overall architectures suitable for deployment across key sectors, including commercial & industrial, digital infrastructure, and energy & utilities.
The ideal candidate has spent a career moving fluidly between big-picture system architecture and the practical details of equipment and component selection - someone who can define how subsystems should interact, predict how a change in one part of the system ripples through performance elsewhere, and translate that understanding into specifications for both commercial off-the-shelf and custom-engineered equipment. Experience from fuel cell, electrolyzer, battery, or electrochemical manufacturing industries - where process systems, equipment specification, applicable codes and standards, and EHS considerations are tightly linked, is highly relevant.
Own the end-to-end system architecture for Voya's metal-fuel power generation platform, defining subsystem boundaries, interfaces, and functional allocation across chemical, mechanical, electrical, and controls domains.
Translate top-level product and customer requirements into detailed, testable specifications at the subsystem, assembly, and component level.
Specify, evaluate, and select equipment, including commercial/off-the-shelf components and custom-engineered assemblies, balancing performance, cost, availability, and manufacturability.
Build and maintain a system-level model and source of truth of how components and subsystems interact and influence one another (thermal, fluid, chemical, electrical, and controls), and use that understanding to define expected performance and acceptable operating ranges across the platform's operating envelope.
Own performance/cost tradeoff analyses between different system architectures to define optimal design targets for each subsystem and inform our R&D priorities.
Conduct trade studies and sensitivity analyses to identify design margins, bottlenecks, and failure modes before they reach hardware.
Own models that quantify balance of system cost/performance with project and site level cost and performance.
Lead or support process hazard and safety reviews (e.g., HAZOP, PHA, FMEA) and ensure designs conform to applicable industry codes and standards and Voya's EHS requirements.
Create and maintain system-level documentation, including architecture and block diagrams, P&IDs, interface control documents, and requirement/traceability records.
Identify technical or integration risks, assumptions, and gaps as early as possible, and drive structured efforts to mitigate or resolve them.
Bachelor’s degree or higher in Chemical Engineering, Mechanical Engineering, or a closely related technical field.
10+ years of experience in systems engineering, process/equipment engineering, or a similarly multidisciplinary technical role, with demonstrated ownership of system architecture from concept through detailed design.
Direct, hands-on experience specifying, sourcing, and integrating both commercial/off-the-shelf equipment and custom-designed components or assemblies.
Strong grasp of how component and subsystem interactions affect overall system performance, with experience defining and validating performance ranges, tolerances, and operating envelopes.
Background in chemical processing, power generation, or electrochemical hardware (batteries, fuel cells, electrolyzers, etc.) strongly preferred — industries where process systems, equipment specification, and safety/regulatory requirements are closely intertwined.
Working familiarity with relevant industry codes and standards (e.g., ASME, NFPA, IEC, UL, NEC, API, as applicable) and EHS/process safety practices such as HAZOP, LOPA, or PHA.
Experience with CAD tools, P&IDs/PFDs, and engineering documentation best practices; familiarity with process simulation tools (e.g., Aspen Plus/HYSYS) a plus.
Experience with DFM/DFA a plus.

Voya is moving into a new headquarters in Hayward, California. The building is being built out now as a blank slate, and we are hiring our first Facilities Manager to help shape it, lead a successful move-in, and build the facilities function for the next stage of company growth.
You will work with every team at Voya, from chemistry and engineering R&D to build and test, fabrication, and the power electronics lab, to make sure they can use the space efficiently and safely to advance our core technology. As the company grows, you will own the broad range of work that keeps the site running: building systems and the subcontractors who modify them, shipping and receiving, inventory, and the new needs that come up along the way.
This is a hands-on role for someone who is as comfortable walking an inspection with the fire marshal as they are troubleshooting a compressor. The systems, processes, and infrastructure you put in place will directly affect the speed, safety, and effectiveness of our R&D organization.
Space & Team Support: Partner with each team to plan, lay out, and adapt their work areas, utilities, and equipment so the space supports their work efficiently and safely.
Building & Process Systems: Own HVAC, compressed air, ultrapure water, exhaust, electrical, and other critical utilities. Hire and manage subcontractors to modify and expand building systems as needs change, and establish preventive maintenance programs.
Safety & Compliance: Help establish Voya’s Environment, Health & Safety (EHS) program with external consultants and internal teams. Own permits and inspections with the city building department and fire marshal, and keep the site safe and inspection-ready.
Shipping, Receiving & Inventory: Run shipping and receiving, including hazardous materials. Set up and manage inventory for raw materials, chemicals, gases, and consumables.
Labs, Shop & Warehouse: Build and maintain gas and chemical storage, shop equipment utilities, forklifts, and racking.
Vendors & Services: Manage contractors, service providers, the landlord, and building services such as access control and security.
Planning & Growth: Manage the facilities budget, plan space and infrastructure for 2027 growth, and take ownership of new operational needs as the company scales.
5+ years of experience in facilities management, facilities engineering, or a related role, ideally in an R&D, manufacturing, laboratory, hardware, or industrial environment.
You’ve set up and run new facilities or programs before, ideally including a build-out or move-in.
Hands-on experience with building and process systems. Can troubleshoot equipment and read MEP and construction drawings; P&ID familiarity and forklift certification are a plus.
Experience with hazardous materials (gases, corrosives, flammables) and with building or running EHS programs: Cal/OSHA, CUPA/HMBP, hazardous waste, fire code. DOT hazmat shipping experience is a plus.
Experience setting up shipping, receiving, and inventory systems.
Strong vendor management: you scope work, compare quotes, and hold contractors to schedule and budget.
Chemical or energy industry background strongly preferred.
Thrives in a fast-paced startup environment and is comfortable taking ownership of whatever needs an owner.
Location: Hayward, CA. Full-time onsite.
