Director, Site Reliability Engineering

About the role

As Director of Site Reliability Engineering, you'll own the core infrastructure layers that everything at Doctolib runs on: cloud infrastructure, database operations, network infrastructure, and observability. You will lead the Doctolib Operations Center and drive a shift from reactive operations to a proactive, world-class reliability culture.

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 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 as a senior technical voice in the Platform org and broader Tech leadership team

What you'll need

• 12+ years in software engineering, including 5+ years leading managers and running infrastructure or SRE organisations at scale
• Track record of taking SRE practices from reactive to proactive — with 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
• Fluent in English; comfortable in fast-paced, international environments

Nice to have

• Experience in healthcare, regulated, or high-compliance industries (HDS, ISO 27001, SOC2, GDPR, data sovereignty)
• Familiarity with Ruby on Rails, Node.js, Go, Python, React, AWS, GCP, Kubernetes, PostgreSQL, Datadog, GitHub Actions
• French language proficiency

What they offer

• Deutschlandticket (Germany-wide public transport pass) fully paid
• 28 vacation days plus 1 additional day for each full calendar year (up to 30 days)
• Work from abroad up to 10 days per year
• Company health insurance with supplementary benefits through Allianz
• Company pension scheme (bAV) with 40% employer subsidy
• DoctoGrowth employee value sharing plan
