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 organisations and elite academic backgrounds. We move fast, keep hierarchy light, and prioritise 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 Role
We’re looking for an iOS Developer Intern to help build and launch a brand-new iOS application from the ground up. You’ll work closely with senior iOS engineers, a product manager, and a designer to develop and iterate on core features using SwiftUI and The Composable Architecture (TCA). This internship offers real ownership of well-scoped features, hands-on experience preparing an app for public release, and exposure to best practices for shipping production-ready iOS apps. You’ll contribute to a product tackling meaningful privacy challenges, particularly in areas impacting women’s digital privacy with the potential to reach 100+ million users.
