AI is being run everywhere, by humans and agents. Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.
We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.
Named to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.
As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work — from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.
For some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.
Our Product Delivery team is the engine that turns vision into impact. We ship early and often, getting valuable features into the hands of customers quickly and iterating from there. We work in the open by default, sharing progress and ideas, and we trust each other to own outcomes. We’re a small but mighty crew where every person plays a critical role and we’re committed to using AI to work smarter and faster.
We’re looking for a Backend Engineer who has an appreciation for all things security and system interconnectivity. This is a very hands-on technical role where you will be responsible for designing, building and maintaining scalable integrations between our core applications, identity providers and data security platforms.
Own deliveries and features from start to finish
Design, build, and own backend services in a microservices-based, event-driven architecture
Implement core domain logic that drives key product workflows and system behavior
Ingest and process high-volume usage and event data from customer-facing endpoints
Build backend services that support operational, analytics, and reporting use cases
Model, persist, and manage domain data, enabling querying, filtering, and lifecycle management
Expose well-designed APIs and webhooks consumed by customers, UIs, and external systems
Power customer-facing UI experiences by providing backend APIs for visibility, analytics, and configuration
3–5+ years of professional software engineering experience building backend services and distributed systems in the Java ecosystem (Java, Spring Boot, Maven/Gradle)
Strong understanding of event-driven architectures, asynchronous processing patterns, messaging systems, and distributed system design
Proven experience designing and maintaining RESTful APIs, web hooks, and service-to-service integrations
Comfortable operating in AWS, GCP, or Azure environments and working with modern observability tooling, logging, and monitoring platforms
A track record of delivering performant, reliable and scalable applications
Excellent collaboration and communication skills in cross-functional teams
Have experience building products in cybersecurity, identity, governance, compliance, data protection, or enterprise SaaS environments
You understand not just how to build systems, but why architectural decisions matter
You can balance scalability, reliability, maintainability, and speed of execution
You think critically about security, observability, and operational excellence from day one
Love the idea of blending software development, distributed systems and data-intensive applications
Strong familiarity with authentication and identity technologies such as OAuth, OpenID Connect (OIDC), SAML, SCIM, Entra ID (Azure AD), Okta, or other enterprise identity providers
Thrive in fast-paced startup environments where ambiguity is the norm
Enjoy shaping culture and engineering practices, not just writing code
Leverage AI tools as an engineer to help you build smarter, faster and better

Harmonic’s GTM team is building the commercial engine for a category-defining company at the convergence of AI and cybersecurity. The team is focused on landing and expanding complex enterprise customers while creating a repeatable, high-performing sales motion.
We operate with urgency, share feedback openly, and treat every customer conversation as an opportunity to sharpen how we position, sell, and deliver value.
We're looking for a Strategic Account Executive to win and grow some of Harmonic’s largest and most-complex enterprise accounts. You’ll own the full sales cycle, from developing a thoughtful account strategy and creating executive-level relationships to navigating technical evaluations, building consensus, negotiating terms, and closing new business.
This role requires more than a strong network or a history of carrying a quota. You must know how to create urgency around an emerging security problem, translate technical capabilities into business outcomes, and lead sophisticated buying groups through complex decisions. You have successfully sold cybersecurity solutions with an average deal size of at least $100K and are credible in the room with CISOs, CIOs, CTOs, and other senior security leaders.
Own the full sales cycle for a portfolio of strategic enterprise accounts, from account planning and prospecting through discovery, technical validation, negotiation, close, and expansion.
Build and execute account strategies that map business priorities, security initiatives, key stakeholders, decision criteria, competitive dynamics, and paths to executive sponsorship.
Develop trusted relationships with CISOs, CIOs, CTOs, security executives, and other technical and business decision-makers.
Lead thoughtful discovery that uncovers business pain, quantifies risk and impact, and connects Harmonic’s platform to enterprise AI governance, data protection, and security priorities.
Navigate complex, multithreaded buying processes involving Security, IT, Legal, Privacy, Procurement, Risk, and executive leadership.
Partner closely with Solutions Architecture to design and lead compelling technical evaluations, demonstrations, and proof-of-value engagements.
Create a net-new pipeline through targeted outbound activity, executive networking, industry relationships, partners, events, and close collaboration with Marketing.
Build strong value cases and executive narratives that differentiate Harmonic and create urgency in a developing category.
Negotiate complex agreements and close six-figure, multi-stakeholder enterprise deals.
Maintain accurate pipeline management, deal strategy, next steps, and forecasting discipline.
Bring customer and market insights back to Product, Marketing, and leadership to influence roadmap, messaging, and go-to-market strategy.
Contribute to the sales playbook by documenting what works, sharing lessons, and helping the broader team scale successful practices.
You build a focused, high-quality pipeline across strategic enterprise accounts and maintain the coverage needed to consistently deliver against quota.
You establish direct, trusted relationships with C-level and senior security decision-makers in your accounts.
Your opportunities are genuinely multithreaded, with clear business pain, quantified impact, executive sponsorship, and a mutually understood decision process.
You consistently progress and close six-figure cybersecurity opportunities, including deals with multiple stakeholders and complex technical or commercial requirements.
Your forecasts are accurate, your account plans are actionable, and risks are surfaced early rather than explained late.
You partner effectively with Solutions Architecture, Marketing, Customer Success, Channel, and Product to create a seamless customer experience.
Your market insights make Harmonic’s positioning, sales process, and strategic account playbook stronger.
Customers view you as a credible advisor on AI governance and security—not simply a software vendor.
Significant experience in quota-carrying enterprise SaaS sales, including a strong track record selling cybersecurity solutions to large, complex organizations.
Demonstrated success selling to strategic enterprise accounts with an average deal size of at least $100K.
Direct experience building relationships with and selling to CISOs, CIOs, CTOs, and senior security leadership.
A consistent record of meeting or exceeding ambitious new-business quotas.
Experience owning complex, multithreaded sales cycles from initial outreach through technical validation, procurement, negotiation, and close.
Strong executive presence and the ability to communicate clearly, credibly, and concisely with senior technical and business audiences.
Excellent discovery skills, including the ability to uncover business pain, quantify impact, and connect a technical solution to executive priorities and measurable outcomes.
Experience building strategic account plans and creating pipelines within named or greenfield accounts‚ not relying solely on inbound demand.
Comfort operating in an early-stage or high-growth environment where the category, messaging, and sales motion are still evolving.
Strong judgment, forecasting discipline, and attention to detail.
Genuine curiosity about AI and a willingness to use AI tools to improve research, account planning, preparation, and execution.
Experience selling data security, DLP, cloud security, AI security, security operations, or adjacent enterprise security platforms.
Existing relationships across the enterprise cybersecurity community.
Experience using channel partners, alliances, and executive networks to develop and accelerate strategic opportunities.
Success selling an emerging category where customer education and internal consensus-building were essential to winning.
Experience at both early-stage cybersecurity companies and scaled enterprise security organizations.
Familiarity with a disciplined enterprise qualification methodology such as MEDDPICC.

🌱 Flourish in the Unknown
We embrace new, unfamiliar situations that require initiative and rapid decision-making. We orient ourselves quickly and deliver results with minimal guidance.

AI is being run everywhere, by humans and agents. Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.
We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.
Named to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.
As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work, from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.
For some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.
We're looking for a Staff Product Manager to take full ownership of a product area focusing on AI Surfaces - the ever-evolving set of places, tools and apps where AI governance has to operate. This is a broad, high-leverage part of what Harmonic builds and sells. You'll be the person who decides which outcomes matter most, in what order we go after them, and be accountable for the value delivered to our customers and our business.
This isn't a role where the strategy arrives fully formed and your job is to deliver it. The market we operate in is changing week to week, and often in ways nobody predicted. A large part of this role is forming a view on where it's heading before all of the evidence is conclusive, committing to that view strongly enough that the team can act on it, and adapting your view when things inevitably change.
Owning a product area end to end, from deciding where it should go over the coming year to the detail of what ships next, and being able to explain and defend the reasoning behind both.
Building and holding a point of view on where your part of the market is going, grounded in what you're hearing from customers, what competitors are doing and how the technology itself is moving.
Deciding which outcomes in your area deserve investment and in what order, and setting out clearly what success looks like so that we can tell honestly when something is or isn’t working.
Spending a real share of your time with existing customers and prospects, on sales calls, in proof-of-value engagements, being comfortable leading those conversations with different types of people such as CISOs, CIOs and the people who work for them.
Collaborating closely across the business, particularly with engineering, design, sales, customer success, so that you can influence decisions well beyond your own team without needing formal authority to do it.
Getting hands-on at the solution level, whether that means exploring an API, pulling and interrogating data yourself, or testing an idea yourself before committing engineering time to it.
Raising the bar for how product work gets done here, so that the way you frame problems, write things down and make decisions becomes something other people start borrowing.
You've owned something substantial before, a product area or a connected set of problems where you set the direction rather than inheriting it. You'll also have strong conviction, because in a market moving this quickly, waiting for certainty often means arriving late. We need someone who is willing to say where they think things are going and stand behind it, while being honest enough with themselves to change course when the evidence tells them otherwise. We would much rather hear a clear view that turns out to be wrong than an overly careful one that rarely commits to anything.
You're also energised by the reality of a startup, where priorities shift, information is incomplete and a lot of what you'll need doesn't exist yet, which means you'll often be building the product and the way of working around it at the same time. If that sounds like a frustration rather than the appeal, this probably isn't the right role for you.
Experience in B2B, particularly selling to and working with large enterprises.
A background in security, data protection or a related field. This isn't a requirement, because we care far more about how quickly you can get to grips with a domain than whether you already know this one.
Experience with products that are enabled via an endpoint agent.
You live and breathe AI trends and latest developments to apply it directly in your role

Our Product Delivery team is the engine that turns vision into impact. We ship early and often, getting valuable features into the hands of customers quickly and iterating from there. We work in the open by default, sharing progress and ideas, and we trust each other to own outcomes. We’re a small but mighty crew where every person plays a critical role and we’re committed to using AI to work smarter and faster.
You will join an early, still-forming team of Deployment Engineers, where you have an opportunity to help define how we operate. You will onboard customers, provide day to day customer support and work through deployment problems.
This is a hands-on, individual-contributor role with direct customer impact. You will manage technically difficult customer issues that require both an inquisitive mind and a desire to provide and excellent customer experience.
When something breaks, you pull the logs, HAR files and configs, write a clean root cause analysis, and hand engineering a sharp escalation.
Provide technical support during onboarding, acting as a trusted technical enablement partner to our customers.
You find opportunities to continuously improve and strengthen the deployment experience for our customers.
You will maintain internal guides and customer-facing documentation.
Beyond deployment support, you feed field findings into the product roadmap and partner with Customer Success, Solutions Architecture, QA and beyond to give our customers a first class experience.
Hands-on experience deploying and supporting enterprise security or endpoint products in customer environments.
Familiarity with MDM platforms (Intune, Jamf or similar), browser extension rollout, SSO/identity configuration and network or endpoint setup.
You are happy working in a multi-OS environment (Windows, Linux, macOS).
A track record of strong customer-facing communication, the kind where you coordinate through an issue, gather the right evidence, and close it cleanly.
Operational discipline: you turn one-off fixes into tracked, documented process so nobody has to firefight the same problem twice.
Some ability to read or write code is a bonus, but the core of this role is technical troubleshooting and customer excellence, not shipping features.
You should be comfortable with getting direct customer feedback and thrive in a fast-moving team where your work ships into the product, not into a backlog.
Engineers from AI-native startups, analytics or data-insight platforms, or security and governance SaaS companies.
We want someone inquisitive and proactive who automates the repeat work, fixes the root cause, and makes life better for both the customer and their colleagues.
Ownership here isn't a buzzword: you have it, and we expect you to use it. If you have an AI-first mindset, and a habit of looking for patterns you can automate away, it will set you apart.

Harmonic Security governs all of it. The AI Governance and Control (AIGC) platform understands user / agent intent and data context in real time, giving security teams visibility and control across every tool and workflow so companies can move faster with AI while minimizing risk.
We operate in one of the fastest-moving spaces in tech: the emerging intersection of AI and cybersecurity. It's a market still being defined, and we're among the first to build natively for it - protecting sensitive data in real time, at the endpoint, with minimal friction for the teams using it. Enterprises get full visibility and control. Their people get to innovate without guardrails slowing them down.
Named to the Rising in Cyber 2026 list, Harmonic is gaining serious recognition and serious traction. We're led by deep cybersecurity expertise and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel.
As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively leverages AI tools to perform their best work, from deep research and writing to building robust processes and automating complex workflows. We expect every new hire to bring a genuine curiosity for AI and a commitment to using it to work smarter, faster, and with greater creativity.
For some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core. We will be transparent about expectations for every role and provide the tools and support needed for you to thrive.
We're looking for a Senior Product Manager who will start by owning our APIs, webhooks and integrations, and the value they deliver for customers. That means bringing Harmonic's AI Risk and Usage Intelligence into the tools our customers already use, and letting them set controls and policies without leaving their existing workflows. Over time it will also mean making it easier for partners to build with us, and shaping how AI agents connect to tools and data. You'll treat integrations as a product with real users, not just plumbing, and you'll decide which connections matter most and build them well. As Harmonic grows, we expect the scope of the role to grow with it.
The market we work in changes quickly enough that we need everyone in product to have a view on where it's heading. In this role, that view is about the ecosystem around us: which platforms our customers are standardising on and where Harmonic needs to connect to them in a year's time. We'll expect you to form that view and hold it with conviction, even when challenged by others.
Owning our APIs, webhooks, MCP servers and integrations end to end, deciding what gets built, for whom and in what order, and being able to defend that order clearly.
Collaborating with our commercial and partnerships teams to understand where integrations and partner opportunities create real value for customers, and translating that into products people use.
Deciding which integrations are worth building and which aren't, using your judgement and understanding of our other product areas to determine where the benefits can be felt the most.
Holding technical conversations with engineers, both ours and those at partners and customers, covering API design, authentication, and common integration patterns to understand how systems fit together and how they might break.
Spending real time with existing customers and prospects, including sales calls and proof-of-value engagements where an integration can make or break a deal, and holding your own in conversations with CISOs, CIOs and their technical teams.
Getting hands-on yourself, whether that means calling an API to see how it really behaves, testing a webhook flow end to end, reading a partner's documentation to assess how hard an integration will be, or prototyping to test an idea before more time is committed.
Producing work, whether that's discovery, specifications or written thinking, that is clear and technically sound enough to stand up to scrutiny from engineers without needing to be fully rebuilt.
You've owned meaningful product work end to end and seen it through to customers, and you can talk not only about what you shipped but about whether it worked and how you knew. You have strong fundamentals to go with that: your writing is clear, your discovery is sound, your prioritisation holds up when someone pushes on it, and you take pride in your quality of work.
You're comfortable being technical. You don't need to write production code, but you're comfortable designing and critiquing APIs, you understand how webhooks, authentication and data flows work in practice, and you can work through detail confidently with engineers. You understand that the people using your products are often developers whose expectations may be very different from those of an end user. You also follow how emerging protocols such as MCP and A2A are changing the way products and AI agents connect, and use this to inform your view of how Harmonic should integrate.
You're also energised by the reality of a startup, where priorities shift, information is incomplete and you'll often need to work out the right approach as you go rather than follow one that already exists.
Experience working alongside business development or partnerships teams, and an understanding of what makes a technology partnership succeed or quietly stall.
Experience in B2B, particularly selling to and working with large enterprises.
A background in security, data protection or a related field, or familiarity with the tools enterprise security teams already run. This genuinely isn't a requirement, because we care far more about how quickly you can get to grips with a domain than whether you already know this one.
You live and breathe AI trends and latest developments to apply it directly in your role

Our Product Delivery team is the engine that turns vision into impact. We ship early and often, getting valuable features into the hands of customers quickly and iterating from there. We work in the open by default, sharing progress and ideas, and we trust each other to own outcomes. We’re a small but mighty crew where every person plays a critical role and we’re committed to using AI to work smarter and faster.
We're looking for an AI/ML Product Engineer to build the insight layer of Harmonic: the ML that makes sense of how people and agents are actually using AI, so our customers can see where it's creating value and where it's creating risk.
This is a hands-on, individual-contributor role with real product impact. You'll take problems from messy raw data all the way to a shipped, customer-facing insight, working directly with product, engineering, security and the customers themselves.
This is about turning AI usage into insight that customers act on. Classification and clustering are how we do that today, but you'll choose whatever approach fits the problem. It's Python-first engineering, not notebook analysis.
Turn raw AI usage data into insights customers can see, trust and act on
Own insight features end to end, from framing the question with users and product partners through to production and iteration
Make sense of unstructured data at scale, with the quality of every output measured and understood
Build and maintain the data pipelines behind your models, and own their deployment and reliability in production
Build the evaluation frameworks, ground-truth sets and error analysis that prove an insight holds up before a customer sees it
Quantify uncertainty and communicate confidence clearly, so the product never presents a shaky signal as a certain one
Shape the product surface itself: what the model should show, to whom, and why
Keep pace with a fast-moving field, adopting new models and approaches as they prove themselves and retiring the ones that don't
Work across a polyglot stack: Python at the core, with Java (Spring Boot) and occasionally TypeScript when the task demands it, deployed on AWS
A track record of shipping production ML that customers or downstream product surfaces depend on, such as text or behaviour classifiers, or clustering and embedding pipelines
Solid applied ML foundations across supervised classification and unsupervised grouping, with a clear view of which model families you've used and why; this role isn't a fit for a background built mainly on forecasting or time-series prediction
Strong production Python for ML and data engineering – code in version control, tested and deployed, not just explored
Rigour about validity: you routinely report precision and recall, confidence intervals and baselines, and you've run experiments or human-in-the-loop review to verify automated conclusions
Experience delivering ML as part of a product team on a customer-visible surface, ideally having owned an insights, analytics or intelligence feature yourself
A quantitative background (statistics, CS, physics, econometrics or equivalent) applied to real data problems
Comfort in a polyglot codebase and a willingness to pick up a second language on the job
Hybrid in our Shoreditch office around two days a week, potential for Remote for exceptional candidates
Have built products in cybersecurity, AI detection, data protection, governance or enterprise SaaS – or have a real interest in how organisations adopt AI safely
Have worked on taxonomy design, data labelling, or entity and intent categorisation in a product context
Have been an early or founding engineer or data scientist and defined the product surface yourself
Care whether a signal in the data is real, and will argue about sampling bias and statistical validity when it matters
Have translated messy data into dashboards, scores or narratives that buyers rely on
Want a senior IC seat with build-it-yourself scope, not a step onto a management ladder
Thrive in early-stage ambiguity and prefer small, fast product companies to large platform teams
Leverage AI tools as an engineer to help you build smarter, faster and better

It's Python-first engineering, not notebook analysis.\n\n\n\n\nWHAT YOU'LL DO\n\n - Turn raw AI usage data into insights customers can see, trust and act on\n\n - Own insight features end to end, from framing the question with users and product partners through to production and iteration\n\n - Make sense of unstructured data at scale, with the quality of every output measured and understood\n\n - Build and maintain the data pipelines behind your models, and own their deployment and reliability in production\n\n - Build the evaluation frameworks, ground-truth sets and error analysis that prove an insight holds up before a customer sees it\n\n - Quantify uncertainty and communicate confidence clearly, so the product never presents a shaky signal as a certain one\n\n - Shape the product surface itself: what the model should show, to whom, and why\n\n - Keep pace with a fast-moving field, adopting new models and approaches as they prove themselves and retiring the ones that don't\n\n - Work across a polyglot stack: Python at the core, with Java (Spring Boot) and occasionally TypeScript when the task demands it, deployed on AWS\n\n\n\n\nWHAT YOU BRING\n\n - A track record of shipping production ML that customers or downstream product surfaces depend on, such as text or behaviour classifiers, or clustering and embedding pipelines\n\n - Solid applied ML foundations across supervised classification and unsupervised grouping, with a clear view of which model families you've used and why; this role isn't a fit for a background built mainly on forecasting or time-series prediction\n\n - Strong production Python for ML and data engineering – code in version control, tested and deployed, not just explored\n\n - Rigour about validity: you routinely report precision and recall, confidence intervals and baselines, and you've run experiments or human-in-the-loop review to verify automated conclusions\n\n - Experience delivering ML as part of a product team on a customer-visible surface, ideally having owned an insights, analytics or intelligence feature yourself\n\n - A quantitative background (statistics, CS, physics, econometrics or equivalent) applied to real data problems\n\n - Comfort in a polyglot codebase and a willingness to pick up a second language on the job\n\n - Hybrid in our Shoreditch office around two days a week, potential for Remote for exceptional candidates\n\n\n\n\nYOU MIGHT BE A FIT IF YOU\n\n - Have built products in cybersecurity, AI detection, data protection, governance or enterprise SaaS – or have a real interest in how organisations adopt AI safely\n\n - Have worked on taxonomy design, data labelling, or entity and intent categorisation in a product context\n\n - Have been an early or founding engineer or data scientist and defined the product surface yourself\n\n - Care whether a signal in the data is real, and will argue about sampling bias and statistical validity when it matters\n\n - Have translated messy data into dashboards, scores or narratives that buyers rely on\n\n - Want a senior IC seat with build-it-yourself scope, not a step onto a management ladder\n\n - Thrive in early-stage ambiguity and prefer small, fast product companies to large platform teams\n\n - Leverage AI tools as an engineer to help you build smarter, faster and better\n\n\n\n\nWHY JOIN US\n\nThis isn't just a job - it's a chance to help define a category. Harmonic Security was named to the Rising in Cyber 2026 list, and we're just getting started. We're building at the intersection of AI and security, carving out an emerging market where the rules haven't been written yet, and the people who join now will write them.\n\nWe believe today's talent is tomorrow's success, and we're committed to creating an environment where you can do the best work of your life.\n\n - Recognized momentum - We made the Rising in Cyber 2026 list, a signal that the market is taking notice\n\n - Rare market opportunity - Join early in a category-defining company at the convergence of AI and security, where your work directly shapes how enterprises tackle one of the biggest unsolved problems in tech\n\n - Competitive pay and meaningful equity - A real stake in Harmonic's success, not a token gesture\n\n - Comprehensive benefits - pension plan and flexible hybrid work\n\n - A small, high-trust team that values transparency, creativity, and continuous learning - no politics, no bureaucracy\n\n - Thoughtful leadership - that cares deeply about your growth, not just your output\n\n - Annual global off-sites - past trips include Lisbon, Portugal and Nashville, TN\n\n - Real ownership - you'll shape the product, the culture, and the direction of the company from day one\n\n\n\n\nHARMONIC'S CORE VALUES\n\n🌱 Flourish in the Unknown\n\nWe embrace new, unfamiliar situations that require initiative and rapid decision-making.

It runs in the browser tab, the desktop app, the agent your engineers kicked off, and the copilot embedded in the tools you already pay for. Harmonic Security governs all of it.
Our AI Governance and Control (AIGC) platform sits on the device, inside the interaction, at the moment of action, reading what AI is actually doing (not just the traffic around it) and acting in under 200ms. Security teams get full visibility and control across every AI surface, including the agentic and MCP layer that traditional tools can't see. Their people get to innovate without guardrails slowing them down.
We're gaining serious traction at the intersection of AI and cybersecurity, and backed by investors who know the space: N47, Ten Eleven Ventures, and In-Q-Tel. As AI adoption inside the enterprise accelerates, the ability to safely observe, control, and enforce policy in real time isn't a nice-to-have. It's mission-critical infrastructure. That's what we build.
Harmonic exists to help enterprises adopt AI safely and at scale. We hold ourselves to that same standard. Everyone here actively uses AI tools to do their best work, from research and writing to building automated workflows. We expect every new hire to bring genuine curiosity for AI and a commitment to working smarter and faster with it.
For some, this means staying open to new tools. For others, it means architecting new systems with AI at the core. We're transparent about expectations for every role, and we give you the tools and support to thrive.
Our Sales team is in the early stages of building something extraordinary. We’re a tight-knit, ambitious group laying the groundwork for how Harmonic goes to market. Every rep plays a critical role in building pipeline, landing new logos, and shaping how Harmonic goes to market. We’re builders as much as sellers - refining the playbook, collaborating across teams, and creating repeatable success.
We’re looking for a Sales Representative to drive growth across the New York region. You’ll own the full sales cycle: identifying prospects, building relationships, running demos, negotiating deals, and closing new business. This is an opportunity to join a category-defining company at the ground floor, building your territory while influencing how we sell as a team.

Build and manage pipeline across assigned territory
Develop account strategies in partnership with leadership
Drive outbound prospecting and convert inbound leads
