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. We are profitable, independent (no VC control), and selectively hire from the top ~1% of applicants. Check our open-source projects here !
The DevOps Platform team builds, maintains and scales the developer tooling platform and infrastructure that hundreds of engineers at Proton rely on daily, across both on-premises and cloud environments. Security isn't an afterthought — it's a core constraint we design around.
Own and scale CI/CD infrastructure handling tens of thousands of jobs daily and growing — that means capacity planning, runner architecture, and making the platform reliable as load patterns shift in ways that don't follow simple rules
Troubleshoot hard infrastructure problems across network, application, and system layers — the kind where the answer isn't obvious and requires pulling on multiple threads at once
Strong Kubernetes experience, including tuning and troubleshooting on-prem Linux systems under real load
Hands-on CI/CD background — GitLab CI specifically is a plus
Software development skills in Python,



Golang or Rust — enough to build and maintain the tooling around your infrastructure, not just configure it
Configuration management experience with Ansible and/or Terraform
