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

Why this role

As the Director of Site Reliability Engineering, reporting to our VP of Platform Engineering, you will 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.

What you’ll do

• Build and run a world‑class SRE org of 25+ engineers across Cloud Infrastructure, Database Storage, Network Infrastructure, Observability Tooling, and the Doctolib Operations Center.
• Own the infrastructure strategy and roadmap—cloud, database, network, observability—and deliver against company OKRs.
• Lead the Doctolib Operations Center: set incident response standards, drive MTTR reduction, embed blameless post‑mortem culture across engineering.
• Architect and execute our multi‑cloud strategy—reducing vendor lock‑in, cutting migration costs, and enabling international expansion.
• Own network infrastructure at scale: load balancing, CDN/WAF, VPCs, peering, zero‑trust networking across a high‑traffic, multi‑country platform.
• Drive observability as a product—give 700+ engineers true visibility into system health and turn observability maturity into an operational excellence lever.
• Lead from the front as a senior technical voice in the Platform org and broader Tech leadership team.

Who you are

• 12+ years in software engineering, including 5+ years leading managers and running infrastructure or SRE organizations at scale.
• Track record of taking SRE practices from reactive to proactive—measurable reductions in incidents and MTTR.
• Strong multi‑cloud and network infrastructure experience: load balancing, CDN/WAF, VPCs, peering at high‑traffic scale.
• Deep database operations background: large‑scale transactional systems (PostgreSQL, Aurora), streaming/CDC (Kafka), data layer FinOps.
• Experience building observability platforms that give teams genuine visibility—metrics, logs, traces, alerting.
• Sharp process thinking: SLOs, error budgets, incident management, blameless post‑mortems.
• Outcome‑driven: track reliability, cost efficiency, and engineering velocity as business metrics, not just technical ones.
• Strong communicator and influencer at executive level—credible with senior engineers and business stakeholders.
• Builder of high‑performing, people‑first engineering cultures.
• Fluent in English; comfortable in fast‑paced, international environments.

Bonus Points If You Have…

• Experience in healthcare, regulated, or high‑compliance industries (HDS, ISO 27001, SOC2, GDPR, data sovereignty).
• Familiarity with our stack: Ruby on Rails, Node.js, Go, Python, React, AWS, GCP, Kubernetes, PostgreSQL, Datadog, GitHub Actions.
• French language proficiency.
• Experience with AI‑augmented infrastructure tooling or ML platform operations.
• Data‑acquisition or post‑acquisition infrastructure integration experience.
