Senior Full-Stack Engineer — AI/ML Systems

Remote-first / NYC drop-in available

Hiring the open contract role on a fast-moving AI platform sitting at the intersection of architecture, AI and professional workflow design — backed by principals with serious pedigree in global architecture and design.

The platform's AI/LLM integration is already production-grade (multi-provider, with automatic fallback). The real gap is full-stack execution: you'll turn UI/UX specs into shipped product, own the database and security layer, and mature an existing test suite into a real QA process.

You're able to bring:

· 5+ years full-stack experience, including real AI/ML integration work (multi-provider LLM orchestration, RAG, agentic workflows) — not just model training

· Strong React front-end craft; genuine comfort turning specs into shipped, polished UI

· Solid SQL/database management and data security/access-control experience

· Comfort formalizing QA — extending an existing test suite with integration/E2E coverage, not building from zero
