About
Join and build a better internet where privacy is the default
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 ( Mail) and expanded into VPN, Drive, Pass, and Calendar—tools used by millions globally to protect their freedom, fight censorship, and keep their data safe. In some situations, 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.

Our business unit, Inbox, is a cross-functional team of about 60 engineers, product managers, designers, and data analysts driving the development of Mail, the company's flagship product, and Calendar. Our mission is to create an end-to-end encrypted solution with a better user experience than any other productivity product on the market. It is not always an easy journey, but it is one that offers the chance to create meaningful impact and drive lasting change.
The Platform team is a subteam of Inbox, responsible for the core components reused across Mail and Calendar. Rather than owning a single feature, the team builds the shared foundations, the tooling and systems other Inbox teams build on top of, so that Mail and Calendar can scale reliably. Over the next year, the team's priority is efficiency and cost reduction.
The Platform team is partnering with the product team on new systems, such as how client apps receive updates from the server (e.g. new email and calendar event delivery), while also improving the performance of systems already in production. Quality and performance are treated as first-class concerns in everything the team ships, not an afterthought.
