About Proton

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. Join us and do work you can truly be proud of. Check our open-source projects here!

The Team:
The internal IT team is what makes Proton possible: it supports everything, from all the internal computer systems, from laptops to the internal documentation solution and videoconferencing. The team collaborates with the security team to provide a safe environment for Proton staff to communicate and develop the products and business.

Current Projects:

Tech Stack and Tools:

The internal IT team sits at the intersection of multiple business functions: engineering, finance, customer support, and more. An exceptional leader in this role will develop connections with the rest of the business, propose changes to streamline processes, evaluate their business impact and ROI, and implement new tools and processes.

What you will do:

What we are looking for:
A seasoned IT professional with hands-on experience in system administration on multiple platforms and successful management experience. A creative mindset trying to tackle challenges rapidly and with limited resources using creativity.

We strive to create equal opportunities, promote open dialogue, and support continuous learning to ensure every voice is heard and respected.

If you need any extra support or reasonable adjustments during the hiring process, please let your talent partner know.
