Executive Assistant

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 500+ 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!

This is Proton’s first Executive Assistant hire. You will work directly with the CEO, keeping his schedule, logistics, and day-to-day running smoothly so he can focus on what matters most. The role starts at a minimum of 50% and is designed to grow: as trust builds, so will your responsibilities.

We are looking for someone at the start of their career, or someone who values flexibility and wants to build something from scratch alongside a fast-moving executive team. What matters most is not years of experience. It is reliability, discretion, good judgment, and a genuine willingness to do whatever it takes, for this role, no task is too small.

What You’ll Do

• Manage the CEO’s calendar: schedule and reschedule meetings, protect focused work time, and make sure the right things happen at the right time.
• Know the CEO’s schedule well enough to coordinate on his behalf — which days he doesn’t take meetings, when he’s traveling, what’s happening before or after a commitment so time doesn’t get booked incorrectly.
• Book meetings and coordinate with internal and external stakeholders directly, representing the CEO’s preferences clearly and professionally.
• Coordinate executive team meetings, management reviews, and board meetings, including logistics and follow-up.
• Handle travel planning end-to-end: flights, hotels, ground transport, itineraries, and any changes along the way.
• Take care of personal tasks and errands as needed — this is a role where no task is beneath you and being helpful is the job.
• Support ad hoc projects as they come up, with minimal direction and good follow-through.

• Reliable above all else: when you say you’ll do something, it gets done. No reminders needed.
• Discreet: you will be close to sensitive information, and you treat that with the seriousness it deserves.
• A quick learner: you pick things up fast, ask good questions, and don’t make the same mistake twice.
• Calm and organized under pressure: when plans change — and they will — you adapt without drama.
•  A clear communicator in English, written and verbal; additional languages (especially German or French) are a real plus.
• Genuinely helpful by nature: you think in terms of what needs to get done.
