About the role

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 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.   About the Team 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.   About the Role We’re looking for a Sales Representative to drive growth across the United Kingdom region. You’ll own the full sales cycle: identifying prospects, building relationships, running demos, negotiating deals, and closing new business.

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.
