AI doesn't run in one place anymore. 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 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 fast. 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 Senior Software Security Engineer to become the authority on our platform's security architecture - and to write the code that embodies it. You'll inherit a platform where the fundamentals of authentication and authorization, secrets and key management, encryption, and multi-tenant data isolation are established, and your job is to sharpen, harden, and evolve them with the depth a dedicated specialist brings that a generalist team can't. You will establish standards and enable the rest of the team to adhere to them. You'll spend the majority of your time writing production code, not producing reports on someone else's.
This is deliberately not a role for someone who wants to sit on a security team finding holes in what other people have already shipped. We want someone who'd rather build the fix into the architecture in the first place - hands-on, opinionated, and accountable for the outcome.
Take formal ownership of Harmonic's platform security architecture - authentication and authorization, secrets and key management, encryption at rest and in transit, and multi-tenant data isolation - and evolve it beyond what a generalist engineering team has had the focus to do
Write production code using our existing languages and tooling (primarily Java, Terraform also Typescript, Rust, Python) to harden and extends these patterns in our core platform.
Collaborate closely with the platform team, who own our architecture and engineering standards, so that security standards are woven into that shared framework rather than sitting alongside it - you'll shape architectural decisions together, not hand requirements over the fence
Manage your own backlog of platform security improvements, prioritized independently of the product roadmap
Run threat modeling and architecture reviews on major new systems and integrations before they ship, so security is designed in rather than retrofitted
Create a close partnership with the Security team to provide evidence that we are adhering to required standards and ensure they are informed where we go beyond
6+ years of hands-on software engineering experience, with deep specialization in security architecture rather than general backend development
Strong working knowledge of Java, and infrastructure-as-code using Terraform and/or OpenTofu
Experience with AWS and its security fundamentals - IAM, network security, container and secrets management.
Strong grounding in threat modeling and secure-by-design principles, applied to real architectural decisions rather than theoretical frameworks
Comfort setting technical standards that other engineers are expected to follow, with the communication skill to bring people along rather than dictate from a distance
Have built or hardened platform-level security in a SaaS company that faces serious enterprise scrutiny (SOC 2, ISO 27001, customer security questionnaires, or similar)
Would rather build the fix into the architecture than find the next hole in someone else's code
Have no patience for security theatre - you measure success by real, shipped improvements to our security posture, not policies, paperwork, or box-ticking that only looks like progress
Leverage AI tools as an engineer to help you build smarter, faster and better
Enjoy being the go-to authority on a topic and setting the standard, rather than gatekeeping other people's work
Are comfortable being the first specialist in this seat, inheriting a solid foundation and having the autonomy - and responsibility - to take it further
Thrive in fast-paced startup environments where ambiguity is the norm
We're still small enough that every hire changes the company.
If you're looking for a role where you can build, make decisions, and have a real impact, you'll find that here. You'll work closely with experienced leaders, help shape how we scale, and have a direct hand in building the kind of company people want to work at.
Recognized momentum — named to Rising in Cyber 2026, a signal the market is taking notice
Rare market opportunity — join early in a category-defining company shaping how enterprises tackle one of tech's biggest unsolved problems
Competitive pay and meaningful equity — a real stake in Harmonic's success, not a token gesture
Comprehensive benefits — 401K/pension, generous PTO, flexible hybrid work
A small, high-trust team — transparency, creativity, continuous learning, no politics, no bureaucracy
Thoughtful leadership that cares about your growth, not just your output
Annual global off-sites — past trips include Lisbon and Nashville
Real ownership — you'll shape the platform, the culture, and the direction of the company from day one
🌱 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.
🔥 Never Full
We raise our hands, take on challenges, and assist others whenever possible. We hunger for opportunities to learn and do more.
🤝 Perfect Harmony
We support one another to create cohesion and unity. We collaborate openly, share feedback honestly, and help everyone produce their best work

","descriptionPlain":"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.\n\nWe 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.\n\nNamed 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.\n\nAs 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.\n\n\n\n\nHOW WE WORK: AI-FIRST BY DESIGN\n\nHarmonic 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.\n\nFor some, this involves tinkering and remaining open to emerging tools; for others, it means architecting entirely new systems with AI at the core.

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 Chicago/Midwest 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.
Own the full sales cycle: prospect, qualify, demo, negotiate, and close
Build and manage pipeline across assigned territory
Develop account strategies in partnership with leadership
Drive outbound prospecting and convert inbound leads
Deliver compelling, tailored presentations and product demos
Collaborate with Marketing, Product, and Customer Success for alignment and feedback
Represent Harmonic at customer meetings and industry events
Contribute to shaping our sales playbook and scaling best practices
4-8+ years of quota-carrying B2B SaaS cybersecurity enterprise sales experience
Experience selling to CIOs and CISOs with an average deal size of $100k+
Track record of hitting or exceeding quota in a closing role
Comfort with outbound prospecting and building a territory from scratch
Strong communication, storytelling, and relationship-building skills
Ability to manage complex sales cycles with technical and business stakeholders
Organized, resourceful, and thrives in a startup environment (startup experience highly desired)
This isn't just a job, it's a chance to help define a category, and to build this chapter of the story from its first page. We're building at the intersection of AI and security, where the rules haven't been written yet, and the people who join now will write them.
