Contribute to our TypeScript services where needed

Contribute to architecture, code quality, technical standards, and continuous improvement of our backend stack

Requirements

Experience with AI automation — building systems that integrate, govern, or orchestrate LLM-driven workflows, not just calling an API

Nice-to-have

TypeScript/Node.js experience, e.g. with frameworks such as NestJS

Experience with data pipelines handling heterogeneous/unstructured input

Familiarity with vector search / embedding stores
