Lead LLM Engineer @Startup IA

What you will own You will be responsible for one thing: Make our AI outputs reliable, fast, and indispensable in real workflows. Concretely: • Design and evolve our LLM / agent architecture

• Own output quality across key use cases (emails, document analysis, etc.)

• Build evaluation systems (datasets, metrics, regression detection)

• Drive fast iteration loops from production data

• Improve retrieval, reasoning, and tool usage

• Ensure production reliability (latency, failure modes, fallback)

• Work directly with product + founders on what to build and why

What this role is really about Most teams fail because: • they don’t know what “good output” means

• they don’t have evals

• they iterate randomly

• they overuse agents

Your job is to fix that. You will turn: • vague user problems

• → into structured AI systems

• → with measurable performance

• → that improve every week
