Key skills: Node.js, TypeScript and Postgres; LLM application patterns (RAG, prompt engineering); AWS and Kubernetes; Next.js and React a plus.
At a glance: London · on-site, at least 3 days a week in the office · 6+ years · posted 20 October (6 days ago) · £110,000–£150,000 plus equity
The Stack's take: Its £150,000 ceiling, plus equity, is the highest figure stated on this list. The catch: the posting sponsors visas for "exceptional candidates", not everyone. Best for: a TypeScript backend engineer who has shipped LLM features.
