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

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 mission is to build the developer platform that makes self-service the path of least resistance - dramatically improving developer experience while reducing platform operational load. This is about creating leverage: every platform improvement multiplies across the entire engineering organization.

•
Quality transformation under growth pressure: We must simultaneously deliver world-class reliability (99.99% availability) while supporting aggressive expansion - new countries, AI-powered products, and the most comprehensive healthcare platform in Europe. This requires architecting for modularity, security, and cost-efficiency from day one, plus building an industry-leading incident management culture. The stakes are real: every minute of downtime affects thousands of appointments and the continuity of care.

What you'll do

•
Lead and scale a high-performing infrastructure organization of 30+ engineers across Infrastructure, Automation, SRE, and Database teams, while maintaining strong engagement and fostering a culture of excellence and ownership

•
Own the infrastructure platform strategy and roadmap that enables Doctolib's modularization journey, delivers on company OKRs, and ensures predictable execution across all infrastructure and automation initiatives

•
Champion platform-as-a-product by building self-service capabilities (infrastructure provisioning, CI/CD, observability, database management) that transform developer experience and unlock team autonomy across the engineering organization

•
Be the guardian of quality and reliability by establishing world-class incident management, driving measurable improvements in availability and performance, and ensuring infrastructure components operate at the highest standards of security and resilience.

•
Accelerate engineering velocity by reducing platform friction, enabling faster modularization, and leveraging AI-augmented development tools to multiply productivity across feature teams

•
Drive the infrastructure transformation from monolith-supporting infrastructure to a modular, multi-service platform architecture - enabling international expansion, product velocity, and operational excellence at scale

•
Act as a senior technical leader within the Platform organization and broader Tech leadership team, bringing strong technical opinions and challenging architectural decisions while clearly articulating how infrastructure investments contribute to company strategy and business outcomes
