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 700+ 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. Check our open-source projects here.
The Localization team makes sure Proton works, and sells, in every market we serve. We own how products, launches, and growth content reach users in their own language and culture. That covers in-app strings, pricing pages, CRM email and app store listings. Some products in the portfolio are mature and others are launching now, so several workstreams run at once against fixed release dates. Beyond delivery, we're building the practice that proves localization's commercial impact through data and experimentation. You'll do well here if you want to own outcomes end-to-end and can handle a vendor escalation and a funnel analysis on the same day.
At Proton, we believe diversity drives innovation and strengthens our mission to provide privacy as a default for all. We are committed to fostering an inclusive environment where all individuals - regardless of race, ethnicity, gender, age, sexual orientation, physical ability, or socio-economic background - feel valued and empowered.
