Staff Engineer Frontend - Paris (x/f/m)

🌍 About the Team

You will join the Healthcare Access stream within the Patient Domain at Doctolib. This stream sits at the very heart of our product: it owns the end-to-end journey patients take to access care, from discovering the right practitioner to booking their appointment and beyond.

Our teams are tackling some of the most exciting and high-impact challenges in digital health: optimizing search and discovery experiences to help patients find the right care faster, building seamless appointment booking funnels that work at massive scale, crafting a delightful and reliable patient app experience, and expanding access to healthcare for new users and new use cases across Europe.

As a Staff Engineer in this stream, your work will directly shape the interfaces and systems used by millions of patients every day. This is where web performance, frontend architecture, and user experience are not just engineering concerns - they are the foundation of how people access their health.

🎯 Your Impact

As a Staff Engineer, you will be a key technical driver for the Healthcare Access stream. With a strong frontend expertise, you will shape the technical vision of our patient-facing products, ensure architectural excellence, and have a lasting impact on the way we build and evolve our platform at scale.

In a stream where organic search and discoverability are key growth levers, you will also be a champion of web performance and search visibility, ensuring our patient-facing surfaces excel on Core Web Vitals, SEO, and emerging Generative Engine Optimization (GEO) practices.

You will work in close partnership with Engineering Managers, Principal Engineers, Product Managers, and Designers to deliver high-impact projects that simplify and improve how patients access healthcare.

• Embrace and champion AI-augmented engineering: leverage AI coding tools (GitHub Copilot, Claude Code...) to boost your own productivity and help the team adopt these practices effectively
• Drive efforts to reduce technical debt, improve system reliability, and proactively mitigate risks

Cross-Team Impact

• Define and build cross-functional programs delivering end-to-end solutions across multiple teams
• Connect teams across the stream by removing collaboration barriers and establishing knowledge-sharing rituals

Mentor and Scale

• Actively mentor and guide engineers across multiple teams through code reviews, pairing sessions, and technical guidance
• Contribute to hiring, knowledge-sharing, and building a culture of engineering excellence across the stream

User First

• Champion a user-centric approach and lead simplification initiatives that reduce complexity and improve the patient experience
• Drive SEO and GEO excellence: ensure our pages are discoverable by both traditional search engines and AI-powered assistants, leveraging structured data, semantic HTML, and content clarity at scale

• Frontend: React, TypeScript, React Native (mobile)
• Backend: Java/Spring Boot, Ruby on Rails
