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. HOW WE WORK: AI-FIRST BY DESIGN 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. ABOUT THE TEAM 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. ABOUT THE ROLE 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. WHAT YOU'LL DO - 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 mo
