Added Apr 28AI Engineer
at ReWorked.ai
Paris, Île De France, FranceRemote
Responsibilities
- Own Windmill's agentic coding and tool/system-building pipeline end-to-end - from the AI backend (planning, tool use, retrieval, self-correction) to the UX and developer experience that wraps it.
Requirements
- Who we're looking for Strong CS fundamentals - algorithms, systems, distributed systems Solid programming skills (TypeScript, Rust a plus) Deep understanding of LLMs, agents, eval methodology - you've built and shipped LLM-based systems, not just played with APIs Rigorous, empirical mindset - you measure before you claim improvement 0–5 years of
- experience - we care more about what you've built than years on a resume Example projects in your first 3 months Redesign the agent's multi-step planning so it can scaffold a full CRUD app (frontend + flow + schema) from a single prompt Build a live feedback UI that lets users steer the agent mid-generation - accept, reject, or redirect individual steps Stand up an automated eval pipeline that catches regressions before they ship and benchmarks every prompt/model change Add a retrieval layer that pulls
Additional details
- The bar: an agent that reliably goes from a natural-language spec to a working, deployed workflow or app - and that developers actually enjoy using.
- Benchmarking : build and maintain the eval harness, task corpus, scoring, and regression tracking.
- Agent loop : design and improve planning, tool use, self-correction, retrieval, execution feedback, multi-file editing, test-driven iteration.
- Integration & DX : own the full surface - UI flows, editor integration, feedback loops, error states - so the
- experience is polished end-to-end, not just the model calls.
- Prompts & models : systematically optimize prompts; experiment with frontier models (Claude, GPT, Gemini, open-weights); fine-tuning / RL where it pays off.
- Ship to production : everything you build goes live and is used by thousands of developers.
