What we do

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 Design System & Accessibility Team and help us become the #1 digital and secure medical companion for patients.

We are part of the Platform domain, whose mission is to build and maintain the common building blocks of our system with a "Platform as a Product" mindset. We abstract and simplify the use of these complex, critical components, enabling product teams to focus on their core mission: building products faster for healthcare professionals and patients.

Why this role matters: With 80% of Doctolib's traffic coming from mobile, we're on a mission to bridge the gap between our Web and Mobile Design Systems. You'll be a key player in unifying the user experience across platforms.

As a Frontend Platform team, we support and empower all other Doctolib Tech and Product teams to create Accessible and best-in-class user experience frontend applications. We achieve our mission by providing a web and mobile design system, by writing supporting tooling around it and the Accessibility topic, and guidance as Accessibility experts.

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

• Design, build, and maintain a scalable Web and mobile Design System built with React and React Native, ensuring a consistent, accessible, and high-performance user experience across Doctolib's web and mobile applications.
• Drive the convergence of Web and Mobile Design Systems, ensuring visual and functional consistency across React and React Native components.
• Develop and maintain React Native components, enabling seamless cross-platform experiences.
• Upskill and mentor team members on React Native best practices, fostering a culture of mobile-first thinking within the Design System team.
• Work hand-in-hand with Product Designers to translate Figma designs into robust, reusable UI components, ensuring visual and functional parity between design and code.
• Champion accessibility (A11y) by embedding inclusive design principles into our Design System, developing accessible components, and providing guidance and tooling to help product teams build compliant and user-friendly experiences.
• Drive adoption and quality of the Design System by supporting teams, improving documentation, establishing usage guidelines, and gathering feedback to inform ongoing improvements.
• Leverage AI technologies to amplify the Design System's adoption and developer experience (DevX), applying prompting and context engineering to create intelligent assistants, automation, and migration tools that help developers build user interfaces more efficiently.
• Occasionally extend your impact beyond the frontend, improving scripts, build processes, or CI workflows that support efficient delivery of the Design System.

Who you are

If you don't meet all the requirements below but believe this opportunity matches your expectations and experience, we still encourage you to apply!

You could be our next team mate if you:

• Have 5+ years of experience in Engineering;
• Have strong hands-on experience with React Native, with a proven track record of building and shipping mobile applications;
• Have a strong understanding of Design System architecture, component-driven development, and the collaboration between design and engineering;
• Have solid experience with React and TypeScript, understanding the nuances between React Web and React Native development;
• Have experience applying or promoting Accessibility (A11y) best practices (WCAG, ARIA, semantic HTML, assistive technology testing);
• Are passionate about knowledge sharing and mentoring, with the ability to upskill colleagues on mobile development;
• Understand the value of testing and code quality as foundations for scalable and robust interfaces;
• Have the ability to adapt and choose the most efficient technologies to solve complex UX and engineering challenges;
• Have proven experiences developing efficient, maintainable and secure products;
• Are comfortable speaking English in your day by day with the team;

Now, it would be fantastic if you:

• Have experience building unified component libraries across Web and Mobile platforms;
• Have a great understanding of JS/TS building and packaging processes;
• Have a great understanding of web and mobile application performance tuning;
• Have native iOS or Android development experience alongside React Native;
