Job description

the company | Senior Full-Stack AI Engineer (CTO track) | Antwerp, Belgium | HYBRID | Full-time | Belgium-based only

the company builds OneView, a legal AI platform that legal teams use in production for contract review, risk and compliance. We recently joined the Anchr software group and are scaling from proven MVP to production-grade platform.

You join as the third person in the team, next to the two founders, and take technical ownership of OneView: retrieval (PostgreSQL/pgvector), LangGraph pipelines, FastAPI backend, React/TypeScript frontend, plus the CI/CD and observability that let a small team ship with confidence. As the team grows, the role grows into CTO.

We care more about AI-native workflows you have shipped to real users than about ticking every box on a stack list. Real R&D backed by a Flemish innovation grant (VLAIO).

Stack: Python/FastAPI, React/TypeScript, PostgreSQL + pgvector, LangGraph, Azure.
