Résumé du poste

Doctolib is seeking a Senior AI Engineer to join the Patient team in Paris. You will design and deploy production-grade search and recommendation systems, leveraging embeddings, vector search, and LLM-based rerankers to guide 100M patients to the care they need.

You will own the retrieval architecture, establish strong baselines, and build observability and feedback loops for online/offline evaluation. Join a mission-driven team building trusted health insights.

Qualifications

• Experience shipping search or recommendation systems to production.
• Experience deploying algorithms to production (ECS-based service on AWS).
• Hands-on experience building end-to-end retrieval: ranking, reranking pipelines; familiar with nDCG, MAP, Recall@k, MRR.
• AI-engineering proficiency: embeddings & vector search, semantic retrieval, RAG, LLM-based or managed rerankers.

Responsabilités

• 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.
• Set up the data/event feedback loops that drive iteration and feed deeper ML later.
• Improve search relevance and ranking on Patient facing products, raising result quality.
• Own production quality: latency reliability, monitoring, and maintainability.
• Partner with ML Engineers and collaborate closely with PMs and SWEs to define, build, and ship AI-powered features that deliver measurable value to users and the business.
