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
