Join our mission, join Doctolib!
We are looking for a Senior AI Engineer to join the Patient team in Paris.
The Patient domain sits at the heart of Doctolib's mission: ensuring everyone has better access to the care they need, receives better care from health professionals, and can actively prevent health problems to improve their wellbeing.
You’ll design the search and recommendation engines behind our health companion, helping 100M patients across Europe instantly navigate to the exact care they need while delivering trusted, curated insights at every step. The retrieval and recommendation architecture you own will directly shape how relevant, fast, and trustworthy that experience is for every one of them.
Your responsibilities include but are not limited to:
Design and build the production search & recommendation architecture: full retrieval, ranking, reranking pipeline with standard and off-the-shelf components (vector search, semantic retrieval, LLM/managed rerankers).
Establish strong baselines first (prompts, RAG, model selection) before reaching for custom ML.
Build evaluation and observability into every stage, with offline and online evaluation.
