The Role

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.

Who You Are

• 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.

• Employee Benefits: your wellbeing isn't an afterthought. We offer strong health coverage, solid retirement options, generous leave, and wellness support so you can bring your best self to work every day
• In-Person Collaboration: Amazing things happen when passionate, smart, and purposeful people get together in the same room. With offices across Geneva, Zürich, Barcelona, London and more, you'll spend most of your time collaborating face-to-face with people who genuinely care about what they're building
• Food: Lunch and snacks are on us every day in our offices so you can focus on the work and not on what's for lunch.
• Transport: getting to the office shouldn't cost you. We cover public transport, bike allowances, or parking, whichever works for you.
• Flexible Working: you own your schedule. Set hours that work for you and your team — because outcomes matter more than when the clock says you started.
