About Harmonic Security

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

Harmonic exists to help enterprises adopt AI safely and  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 People team is small but mighty.

There's me (Head of People Operations), our Founding Recruiter Kareema (based in the US) and hopefully you.

You’ll be our first People hire in the UK. You’ll own the day-to-day People function here, but you won’t be on an island. We work closely together, share ideas, and jump in to help each other when needed.

Reporting directly to the Head of People Operations, you’ll partner closely with our UK leaders and collaborate with teams across the business.

Almost half of Harmonic is based in the UK, but we don’t have anyone from People sitting with them today.

That’s why this role exists.

You’ll become the trusted People partner for our UK team. You’ll coach managers, support employees, own UK compliance, improve our processes, help with hiring, and make sure the London office is a place people enjoy coming to.

You’ll have a lot of ownership. We trust people to make good decisions, and we expect you to help shape how People Operations evolves in the UK, not just execute someone else’s playbook.

This is a true generalist role. You’ll probably enjoy it if you like switching context, wearing a lot of hats, and building things from scratch.

Some days you’ll be helping a manager navigate a difficult employee conversation. Other days you’ll be screening candidates, auditing our HRIS (Rippling), reviewing benefits, supporting payroll, planning an office event, or figuring out whether
