Senior Product Manager (Inbox) - B2B

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 .

Mail & Calendar are Proton's largest product surface and the entry point for most of our millions of users. The team runs 50+ engineers and is in the middle of a significant push into B2B - building the features, admin infrastructure, and organizational workflows that businesses need, without compromising the privacy guarantees that brought them to Proton in the first place. The PM challenge here is real: you're building for both individual users and the organizations that manage them, under privacy constraints that rule out the instrumentation most B2B products rely on. If that sounds like an interesting problem, keep reading.
