Director, Site Reliability Engineering- Paris (x/f/m)

Why this role As our Director of Site Reliability Engineering , reporting to our VP of Platform Engineering, you'll own the core infrastructure layers that everything at Doctolib runs on: cloud infrastructure, database operations, network infrastructure, and observability . You will also lead the Doctolib Operations Center (DOC) and drive a decisive shift from reactive operations to a proactive, world-class reliability culture. This is a rare opportunity to shape the infrastructure backbone of Europe's leading healthtech company, at a moment when Doctolib is actively expanding multi-cloud capabilities, scaling to new countries , and building the reliability culture that will define the next decade of healthcare innovation. Why this is an extraordinary challenge Real stakes, every day. When Doctolib is down, consultations don't happen, diagnoses are delayed, care journeys are interrupted. The infrastructure you build is a direct lever on patient outcomes — in a world where 8 of the top 10 causes of death in Europe are preventable. A once-in-a-generation platform transition. Multi-cloud, monolith modularisation, international expansion — all happening simultaneously. You won't inherit a finished platform. You'll define what it becomes. Reliability as the competitive moat. As we scale AI health companions, automate clinical workflows, and launch across Europe, the speed and resilience of the platform directly determines how fast 700+ engineers can ship innovations that change healthcare. A cultural build, not just a technical one. The incident response culture, observability standards, and operational ownership model you establish here will shape how Doctolib engineers work for years to come.
