Join a team of passionate and hardworking entrepreneurs to transform healthcare!

Working in the tech team at Doctolib involves building innovative products and features to improve the daily lives of care teams and patients. We work in feature teams in an agile environment, while collaborating with engineering, design, and business teams.

What you'll do

We are looking for a Senior Software Engineer to join our Core Front team and help us become the #1 digital and secure medical companion for patients.

More specifically, you'll join a team of engineers and accessibility specialists working on advanced frontend development topics.

The Core Front Team serves as Doctolib’s frontend platform team, focused on delivering high-performance, accessible foundations for all our web applications. Its mission is to empower product teams to create exceptional user experiences at scale through standardized tools, frameworks, and best practices.

As a Senior Software Engineer, your responsibilities will include, but are not limited to:

• Lead the design, development, and delivery of core frontend services such as Internationalization (i18n), Client Storage, HTTP Client, and more, empowering all Doctolib product teams to build high-quality, user-centric applications.
• Enhance productivity and scalability through frontend tooling initiatives, using Vite and Rspack to accelerate builds, streamline CI/CD, and improve the frontend developer experience.
• Champion a User First mindset by embracing our Design System (Oxygen), delivering accessible, robust, and reusable components that enhance user experience and reliability across all our products.
• Take ownership of complex technical challenges, including large-scale migrations, architectural evolution, and distributed frontend systems using technologies like Module Federation.
• Establish and maintain best practices (“golden paths”) for frontend development, covering areas such as performance, automation, testing, and CI, in partnership with Staff Engineers.
• Mentor and support fellow engineers, sharing knowledge, reviewing code, and advocating for high standards in code quality, accessibility, and developer experience.
• Maintain a continuous learning mindset, proactively researching and evaluating new technologies, processes, and tools to keep Doctolib at the forefront of frontend engineering excellence.

About our tech environment

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.
