Join Proton and build a better internet where privacy is the default

Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right.

Join Proton and build a better internet where privacy is the default

At Proton, we believe that privacy is a fundamental human right and the cornerstone of democracy. Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security, and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive, and Proton Pass. These tools empower individuals and organizations to take control of their personal data, break away from Big Tech’s invasive practices, and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information. In some cases, Proton’s services have even been instrumental in saving lives by enabling secure and private communications in high-risk situations.

Proton is a profitable company that does not rely upon VC funding, supporting over 100 million user accounts with a growing team of over 500 people from over 50 different countries, from the world's top companies and universities. We value intelligence, learning potential, and ambition in our hiring process. Adaptability is key as we navigate uncharted territories and redefine how business is conducted online.

Hiring at Proton is highly selective, with less than 1% of candidates hired. We believe smaller teams of exceptional talent will always prevail over larger teams with lower talent density. You will have the opportunity to work with many of the world's top minds in their fields, ranging from former international math and science olympiad winners to chess champions.

We have a global mindset and big ambitions but remain a start-up at heart. We value empowerment and flexibility and keep our structure flat to keep moving fast and avoid unnecessary politics.

The Account Team

The Account team owns the capabilities across the full user lifecycle - from acquisition and account creation, through protection, recovery, and user management, to retention and end-of-life. Account is one of the key functions that are positioned centrally and contribute to all of Proton's products.

Tech Stack and Tools:

• Our web client is based on React/Typescript, our mobile code is based on Kotlin (on Android) and on Swift (on iOS), with a growing shared codebase in Rust.
• All our client-code is open-source and GPL3.
• We are migrating our infrastructure to Kubernetes.
• Everything runs on premise in Proton's data-centers.
• To organize our work we use classic tools such as Jira and Confluence.

Future plans:

With the increasing number of Proton product releases, we have ambitions to accelerate this process by unifying the Account experience across all devices, clients, and audiences.
The accounts team is growing fast, which creates future opportunities to lead and take ownership of significant areas of the system.

What you will do:

We believe in small empowered teams that focus on delivering large impact. This requires strong engineers with product engineering mindset who can collaborate well, take ownership, and do whatever is needed to achieve our ambitious goals.

Proton was founded in 2014 by scientists from CERN on a simple truth: privacy is a fundamental human right.

This particular team requires someone who is a strong generalist, who thrives with ambiguity.

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;

• Have the ability to adapt and choose the most efficient technologies to solve complex UX and engineering challenges;
