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.
The Performance Marketing Team
Proton for Business serves organizations that genuinely can't afford data leaks — from journalists and activists to government bodies and enterprise security teams.



The Performance Marketing team owns paid acquisition across all of Proton's products, with B2B now a strategic growth priority. You'll work directly with the Performance Marketing Lead, running campaigns end-to-end across Google, LinkedIn, and beyond — while managing an external agency and partnering with the Ad Tech, Brand, and B2B product teams. This role suits someone who's equally comfortable in the campaign manager interface and a budget spreadsheet, and who pushes back on funnels that don't convert.
What You'll Do
Own end-to-end paid B2B campaigns across Google, LinkedIn, and Meta — from brief to creative to budget to optimization — with full accountability for CPL, ROAS, and CAC
Manage and performance-manage an external performance marketing agency: set briefs, oversee execution, evaluate results, and hold them to the same bar you hold yourself
Implement and maintain privacy-first t
