Description du poste

What youll do

As our Platform Engineering Director you will be a key driver of Doctolibs technical transformation. Youll 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 Doctolibs 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.
