Senior Fullstack Engineer (AI-Native) — Freelance via Shakers

We’re hiring a Senior Fullstack Engineer to help build the enterprise backbone of an AI hiring intelligence platform that’s redefining recruitment through voice-first, capability-based assessment.

You’ll join a lean creative engineering team with a flat structure, high ownership, and zero bureaucracy. The product is AI-native — and so is the team.

What you’ll do

  • Architect and ship high‑concurrency APIs and event‑driven systems (NodeJS, NestJS, GraphQL, PostgreSQL)
  • Define enterprise‑grade architecture: GDPR‑safe, audit trails, permissions, cloud‑ready by default
  • Integrate LLMs (Gemini and others) into the product in a measurable, monitored, production‑safe way
  • Build reliability foundations: monitoring, logging, retries, runbooks
  • Own features end‑to‑end — from vague brief to production

Must-haves

  • Hands‑on with LLMs in production (Gemini a plus)
  • Event‑driven architecture, Prisma, Terraform
  • Reliability mindset: monitoring, QA, retries

Format

  • 100% freelance via Shakers
  • Hybrid in London – flexible (EU timezone)

If you’re AI‑native in practice and want real end‑to‑end ownership in a high‑taste studio, apply.
