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. 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. In some
situations, Proton has literally helped save lives!
We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Our 500+ team members across
50+ countries come from leading organizations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritize
impact over optics. If you want to do meaningful work with exceptionally high-caliber people, this is it. Join us and do work you
can truly be proud of. Check our open-source projects here!
The Proton Drive Desktop Team
Proton Drive is our secure, private cloud storage and collaborative editing suite, with clients on Windows, Mac, iOS, Android, and
Web. One platform is missing: Linux. You will build it from scratch. 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.

Veo is a global leader in AI-based sports camera technology. Our innovative, fully automatic camera solution enables sports teams to record matches and training sessions without a camera operator. We’re democratizing the world of sports by granting video analysis for teams on all levels—a privilege that used to be only for the few. More than 40,000 clubs in 90+ countries record their games every week. But what truly sets us apart? Our people. We’re a diverse group of innovative thinkers, creators, and problem-solvers who believe in delivering an incredible product—and having fun while doing it. The Opportunity At the heart of our technology is an embedded Linux–based camera system that records sports matches using multiple sensors. Using our advanced video processing algorithms, these streams are stitched together to present one continuous playfield. Our AI and cloud teams then process the video using proprietary models that lead the industry in our field, enabling players and coaches to access detailed statistics such as goals, ball possession, passes, and more. While dedicated teams own most of the video processing and AI development, you will interface closely with both worlds and have the opportunity to gain exposure across these domains. Most work in this role focuses on Rust- and Python-based user-space Linux applications, Linux platform engineering, and firmware architecture, rather than low-level hardware or driver development. Our firmware stack primarily uses Rust, Python, and C, and fluency in at least two of these languages is preferred.
