Site Reliability Engineer - Storage

About the role

<h3>Join Proton and build a better internet where privacy is the default</h3> <p>Proton was founded in 2014 by scientists from CERN on a simple truth: <strong>privacy is a fundamental human right</strong>. 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.</p> <p>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.
