Why this role

As our Director of Infrastructure platform, you will be a key driver of Doctolib’s technical transformation. You’ll lead our move from a monolithic architecture to a modular, multi-service environment, enabling both product velocity and operational excellence at scale.

You will own our platform as a product mindset, fostering team autonomy while ensuring cost-efficiency, reliability, and security. Overseeing a team of 30+ engineers (Infrastructure & Automation), your leadership will directly impact the daily experience of 120+ feature teams, +700 engineers, and the care journey of millions of patients and healthcare professionals. This is a rare chance to shape the platform for Europe's healthcare future. You'll work with talented engineers, solve complex distributed systems problems, and make technology decisions that directly improve healthcare for millions.

Why this is an extraordinary challenge

Engineering the foundation for 5x growth: We're transforming Europe's leading healthcare platform - serving 420,000+ HCPs and 90M patients - from monolith to modular architecture. This isn't just technical refactoring; it's enabling Doctolib to scale to new countries, multiple medical specialties, and new product verticals while maintaining mission-critical reliability for millions of care journeys daily.

Velocity as a competitive advantage: Our 2026 ambition is to innovate 50% faster while drastically reducing incidents and driving healthcare professional satisfaction.To get there, we must transform platform capabilities from bottleneck to accelerator - enabling 100+ feature teams to ship independently, safely, and at pace. The business impact is direct: faster innovation cycles translate to better patient access, higher practitioner satisfaction, and competitive differentiation in a rapidly evolving market.

Building true platform-as-a-product: We're pivoting from "platform-as-support" to "platform-as-product" to unlock team autonomy at scale. Your
