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 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.

Drive Foundation
Drive Foundation is the backbone of Proton Drive. We ensure that cross-client initiatives are executed consistently and efficiently. Whether it’s aligning multiple clients, maintaining documentation or the RFC process, or building robust SDKs, our team lays the groundwork that makes the entire Drive experience work seamlessly.
We’re currently focused on developing SDKs that encapsulate the core functionality of Proton Drive. The SDK comes with two implementations, one in C# for desktop and mobile clients and second in TypeScript for web client. Our SDKs primarily serve internal clients today, but our long-term vision includes integrating them across the Proton ecosystem—and even enabling third-party applications to interface with Drive.
As a Drive Foundation Engineer, you will play a crucial role in designing, implementing, and maintaining the foundational components that power Proton Drive applications. You will work collaboratively with Drive teams, including backend, web, mobile, or desktop developers, to ensure seamless integration and optimal performance across various client applications.
