## Job description

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](https://proton.me/community/open-source).

Purpose of the role:

Storage is at the very center of everything we do. Whatever needs to be persisted eventually uses our Storage infrastructure. For this we run our infrastructure predominantly on-premise in multiple data centers. In this role you will join the Storage SRE team that is responsible to automate, scale, enhance and run our Storage infrastructure. The office locations we hire into for this role are Geneva/Switzerland or Paris/France.

What you will do:

- Design, build, and operate resilient Storage infrastructure for Proton’s most critical production services
- Develop and maintain automation tools to enhance deployment processes, configuration management, and service reliability
- Improve monitoring, alerting, and incident response to maintain high availability and rapid issue resolution
- Optimize and scale Proton’s infrastructure
- Collaborate with product and security teams to implement best practices for privacy and data protection at every layer of the stack
- Document and share knowledge to foster a culture of learning and continuous improvement within the team and beyond
- Work closely with a group of Back-End Engineers and Architects to build resilient, massively-scalable solutions for millions of people to rely on
- Document back-end capabilities and their proper use
- Join the oncall rotation to operate the Storage service

Job requirements:

- Experience building complex production systems
- Operational experience, demonstrating the ability to diagnose and troubleshoot complex problems for critical systems
- Experience with software development
- Solid understanding of security best practices
- High-level understanding of cryptography concepts

Bonus points for:

- Experience with storage systems (e.g. Ceph, Seaweed or Tape)

Even if you don’t meet all the requirements listed above, but feel you could still be a great fit, please apply.
