Senior Systems & Reliability Engineer (VPN)

Barcelona; Geneva

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 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.

At ProtonVPN, we're on a mission to provide secure, private internet access to everyone—even in the most restrictive environments. Our infrastructure spans thousands of servers worldwide, operating on a distributed architecture that connects our suite of applications across platforms.

As a Systems and Reliability Engineer on the VPN Infrastructure team, you’ll help design, implement, and maintain the robust systems that keep our users connected when they need privacy and security most.
