Senior Fullstack Engineer (AI-Native)

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

• Strong NodeJS + NestJS + GraphQL + PostgreSQL
• Hands-on with LLMs in production (Gemini a plus)
• Event-driven architecture, Prisma, Terraform
• Reliability mindset: monitoring, QA, retries

Format

• 100% freelance via Shakers
• Long-term engagement
• 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.
