Full Stack Engineer

Senior Full Stack Engineer (TypeScript,AI/LLM) | London | £80,000 - £120,000] | Hybrid, 3 days onsite We're partnering with an AI-native software company building mission-critical tools for frontline public sector teams. Their users work in high-pressure environments where slow, fragmented systems cost time that matters. They're replacing that with a single, intelligent platform built around how people actually work. They're now hiring a Senior Full Stack Engineer to join as an early member of a small engineering team, someone who wants real ownership of the product from day one rather than a backlog handed down to them. What you'll be doing

• Owning features end to end, from talking to users and forming your own view on what to build through to shipping in production
• Building LLM-powered and real-time features that go beyond simple prompting, including voice and live data workflows
• Building across a modern TypeScript stack (React, Next.js, Node, NestJS) backed by Postgres and AWS
• Working directly with the founders, with real influence over technical and product direction What they're looking for
• 4 to 9 years of experience, with strong, production-scale TypeScript and React
• Solid back-end depth in Node (NestJS a plus), not just front-end
• Startup or scale-up experience where you've shaped what got built, not just executed a spec
• Hands-on experience building with LLMs or AI systems, not just using AI tools day to day
• Someone who thinks in user problems first and technical solutions second
• Able to obtain UK security vetting (right to work and a clean UK address history required) Why this one's worth a look
• A small team of generalists who move fast, ship often and keep a high bar
• Real early-stage ownership in a company with a clear, meaningful mission
• Products used by people doing genuinely important work every day For more information, hit APPLY and I'll book in a call with you to answer any questions you may have.
