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.

The Team

Proton VPN gives millions of people a private connection to the internet, including people in countries where the internet is censored.



It runs on thousands of bare-metal servers. We choose the hardware, the datacenters, and the networks ourselves, and we operate all of them.

The VPN Site Reliability Engineering team builds and runs this fleet. It has eight engineers: six site reliability engineers and two engineers who look after day-to-day fleet health. The fleet runs Debian, is automated with Ansible and Python, and is monitored with Prometheus, VictoriaMetrics, and Grafana. The team has kept the service stable through several years of fast growth.

The role:

We are hiring an engineering manager to lead this team. You will report to the VPN Engineering Director and work from our Geneva or Barcelona office.

The fleet keeps growing as more people use Proton VPN. To stay ahead of that growth, the team is investing in two areas, and you will lead both.

1. Automation. Engineers still do much of the provisioning, deployment,
