Application process
- This is a greenfield project with high visibility inside Proton and across the open-source community — our entire client codebase is published under an open-source license, and this will be the first public example of how to build a native application on top of the Proton Drive SDK.
- You will work closely with our Windows and Mac engineers to ensure feature parity, and you will contribute to our platform-agnostic SDK and CLI tooling as the Linux surface area demands it.
- If building something that the Linux community has been waiting for, and doing it in the open, is the kind of work that gets you out of bed — this role is for you. Tech Stack and Tools

- Linux packaging and distribution (Debian, Fedora-based) What You'll Do
- Own the design and implementation of the Proton Drive Linux desktop client, built greenfield from the ground up.
- Ensure the codebase meets the standard expected of production open-source software — it will be read and built upon by developers beyond Proton.
- Integrate deeply with Linux-specific system components, including the filesystem layer for our file synchronization engine.
Contacts
- Since then, we’ve built the world’s largest encrypted email service (Proton Mail) and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe.
