Design and ship AI agent workflows
Get an overview of our ongoing initiatives, challenge and improve them
Design and deploy background AI agents that autonomously handle specific engineering work: bug triage, diagnostics, patch suggestions, and code review
Define prescriptive agent workflows and skills that teams can adopt and extend
Improve our AI review pipeline
Own the specs-to-production pipeline
Implement automated workflows from design/spec to merge-ready code
Build faster feedback loops through better test generation and AI-assisted validation
Consolidate individual and team-level AI practices into a pragmatic, enforced approach: move from an artisanal one (Cursor + Claude Code per engineer) to a systematic one
Co-own the AI toolchain roadmap
Work directly with our Staff Engineers and CTO to define what gets built, in what order, and why
Join feature teams on a regular basis to keep the roadmap grounded in real constraints

Founder or early-stage operator background: you have built and shipped an AI product, talked directly to users, and dealt with real constraints.
Product mindset with technical depth: before shipping a feature, you ask who uses this and why.
Hands-on AI/LLM experience: you have developed with AI agents, LLM APIs (Claude, OpenAI, etc.), or agentic frameworks in production.
5+ years of technical experience, Python environments (our stack is Python + Django, TypeScript, Rust).
Influence without authority: you move people through ideas, prototypes, and clear thinking.
Structured, autonomous execution: you can research a problem space, propose an opinionated solution, document it clearly, and drive it to completion with minimal oversight.
Fluency in English, written and spoken.
Background in platform engineering or developer tooling (not required).
Familiarity with CI/CD optimization (not required).
Basic knowledge of DORA metrics or DX Framework (not required).
Fluency in French (not required).
