Product AI Engineer

Product AI Engineer - London - £80–90K Build the product. Own the outcome. We're partnering with a well-backed, early-stage AI company building AI agents for one of the world's largest and least-disrupted industries: the firms that design, build and maintain physical infrastructure. Think agents and software that plug straight into the systems some of the biggest engineering consultancies on the planet already run on — and take real operational work off their hands. They're early, moving fast, and have a genuinely generational shot at defining how this industry works with AI. It's a small, high-performance team: direct, quality-obsessed, and happiest solving hard problems together. This role sits alongside the VP Engineering, on the core product. What you'll own You'll build and ship across a modern TypeScript stack — frontend, backend, and the integrations that wire the platform into customer systems. Real end-to-end ownership: understand the problem, decide how to solve it, ship it, and make sure it actually works in the wild. Day to day that looks like shipping product features across React and Node, developing APIs, data models and integrations, and building LLM-backed features — prompting, tool use, the lot. You'll turn ambiguous problems into simple working solutions, use AI heavily in how you build, find and fix problems before anyone asks, and own your work from first sketch to production. What you'll bring 3+ years' software engineering experience Strong TypeScript — this one's non-negotiable A track record of shipping real products across frontend and backend Hands-on experience with LLMs, agents or AI APIs Exceptional diligence and genuine attention to detail High agency, strong ownership, and real comfort with ambiguity Sharp product judgement Startup experience is a strong advantage. What's on offer £80–90K base Direct exposure to the VP Engineering Real ownership of meaningful parts of the product A seat that shapes both product and technical direction as the company scales Location: Office-first, central London (Farringdon). This is an in-person role for someone who wants to build shoulder-to-shoulder with a high-performance team.
