Job description
Doctolib is growing, and we are hiring a Senior Fullstack Software Engineer in Nantes to join the Business Performance team.
Your mission will be to help Doctolib reinforce its position as a leading healthcare technology platform by building high-quality products that improve the daily lives of healthcare professionals and patients. You will work in feature teams developing solutions that directly impact millions of people across Europe.
Working in the tech team at Doctolib means building innovative products and features to improve the daily lives of care teams and patients.
Your responsibilities include but are not limited to:
- Collaborate with product managers, designers, and engineers to build features that deliver value to healthcare professionals and patients
- Design and implement technical solutions ensuring performance, security, and usability across our fullstack applications (React, Ruby on Rails, JVM ecosystem)
- Strong design and architecture skills: you contribute to technical decisions, not just implementation
- A track record of balancing delivery speed, reliability, and maintainability under real constraints
- Comfortable with AI‑assisted development workflows, and able to help your team raise their own proficiency
- Share your expertise and collaborate across teams to evolve Doctolib's architecture and technical standards
- In BP, the scope is broad, and the topics are diverse. Teams are small, and decision-making is close to the action. And if you want to understand how a tech scale‑up generates (and protects) its growth, you’ll have a front‑row seat.
- Our solutions are built on a single fully cloud‑native platform that supports web and mobile app interfaces, multiple languages, and is adapted to country and healthcare specialty requirements.
- Our stack is composed of Rails, TypeScript, Java, Python, Kotlin, Swift, and React Native.
- We leverage AI ethically across our products to empower patients and health professionals. Discover our AI vision here.
