Join our mission, join Doctolib!
We are looking for a Senior AI Engineer to join the Patient Health Platform team in Paris.
The Patient domain is at the heart of Doctolib's mission to help everyone be in better health. Our teams build the Health Companion that millions of people rely on every day - a seamless, AI-powered experience that empowers patients to take an active role in their own health journey.
Find Your Practitioner (FYP) focuses on making access to care faster, easier, and smarter. From our practitioner directory and online booking to intelligent care search assistance, FYP ensures that every patient can find the right professional at the right time.
Preventive & Continuous Care Companion (P3C) goes beyond the consultation room. This stream builds the tools that help people prevent health issues before they arise, stay connected with their care team between appointments, and manage their health over time - through personalised health tracking, prevention campaigns, care plans, and AI-powered health guidance.
Together, these two streams shape a product that is not just a booking tool, but a true companion for health - recommended by practitioners and trusted by patients.
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.
