Platform Engineering Director - Paris Doctolib - Paris - Plein temps (> 32 heures)

As our Platform Engineering Director, 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. Reporting to our VP of Security & Platform, 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 hundreds of engineers and the care journey of millions of patients and professionals. Why this is an extraordinary challenge - Modernization in progress: We are transitioning from a large Ruby on Rails monolith (~2.1M LoC) to a multi-service architecture. This brings new complexity in dependency management, observability, cost control, and operational processes. - Platform as a Product: We are pivoting from a platform as a support' to a platform as a product' model. Our goal: empower every engineering team to self-serve, deploy, and operate independently - while delivering fast, securely, and cost-effectively. - Autonomy at Scale: We want true team autonomy, but many critical platform capabilities (e.g., secure, on-demand database provisioning, CI/CD, observability, service discovery, self-service infra) remain to be built or matured. - Change Management: This transformation requires a deep mindset shift - your leadership in change management and culture-building will be crucial. Your key missions & expected impact Accelerate Modularization of Doctolib - Lead and accelerate the modularization of Doctolib's technical stack to enable product velocity and international scale. - Drive the architectural and technical enablers (e.g., clear boundaries, robust platform services) that allow other teams to extract and independently evolve Patient and Pro user journeys, as well as country/specialty-specific features. - Ensure at least 25% of frontend code is migrated out of the monolith this year, and empower rapid internationalization through modularity - not by directly owning all extractions, but by making them possible. Build a Product-Grade Developer Platform - Inspire and lead your teams to deliver world-class platform products (infra provisioning, database on demand, ephemeral environments, CI/CD, observability) as self-service, productized experiences. - Promote operational excellence by establishing clear processes, robust documentation, and measurable objectives (NPS, team operational load, monolith master red ratio, etc.). - Drive platform adoption as the path of least resistance, fostering a culture of autonomy and high standards. - Accelerate development cycles so new countries, clusters, and product verticals can be delivered faster, with higher quality and reliability. Deliver a Major Uplift in Quality and Reliability - Transform the quality bar: Lead a major transformation to drastically reduce incidents and raise reliability across all platform and infrastructure domains. - Ensure robust, scalable, and secure database provisioning. - Build an industry-leading incident response function and automate security controls, aiming for world-class reliability and security for all platform products. Your team The Platform domain is divided into three main activities, and you will be responsible for two of them (Infrastructure and Automation Platform): - Application Platform (not in scope for the role): Provides reusable, easy-to-consume products for engineering teams (e.g., identity providers, asynchronous communication engines). - Infrastructure which focuses on: - Database optimization: Management of large AWS-hosted transactional databases, aiming to provide easy database provisioning, smooth migration from monolith to modular systems, and observability tooling. - SRI Teams: - Observability (monitoring, logging, adapting to a modular world) - Core Infrastructure (EKS, load balancers, proxies, patching, etc) - Automation Platform which focuses on: - CICD environments for fast feedback loops and developer productivity. - AI-augmented development (tools like Copilot, Cursor). - "Dev Duty": Ensuring production incidents are quickly handled.

We are looking for a Senior Database Reliability Engineer to join the Doctolib Database Optimization team in the Platform team. The team which you will join ensures the reliability and performance of our datastores while fostering a platform mindset in our transition to the you build it, you run it paradigm. It is a multidisciplinary team made of both Site Reliability Engineers and Software Engineers, which enables us to have a complete view of the problems we need to solve and of the alternative solutions we might implement to solve them. As a Database Reliability Engineer (DBRE), you will play a critical role in our mission for our main datastores: PostgreSQL / AWS Aurora, Kafka, Couchbase and OpenSearch. Your responsibilities include but are not limited to: - Reliability Engineering: Ensure high availability of our datastores and our own operational efficiency through observability, automation, tooling, backup strategies, disaster recovery planning and process improvement, - Database maintenance: Handle database infrastructure maintenance including upgrades, performance optimization, cost optimization and capacity planning, - Incident mitigation: Participate in incident response for datastore-related issues in production during business hours, when the issue cannot be fixed by the responsible feature team, - Database-as-a-service: Empower feature teams with database tooling, guidelines, training and support to manage and use their databases efficiently, - Datastore expertise sharing: Stay up-to-date with datastore technology evolution and share knowledge with the team on new features, best practices, and industry trends. About our tech environment - Our solutions are built on a single fully cloud-native platform that supports web and mobile app interfaces, multiple languages, and is adapted to the country and healthcare specialty requirements. To address these challenges, we are modularizing our platform run in a distributed architecture through reusable components. - Our stack is composed of Rails, TypeScript, Java, Python, Kotlin, Swift and React Native. - We leverage AI in an ethical manner across our products to empower patients and health professionals.
