About the role

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.   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.   The role 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.   What You'll Do • 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
