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 Role

As VP Design, you will own and lead the design function across both Product Design (user experience, interface, service design) and Brand / Marketing Design (visual identity, campaign creative, brand experience). You’ll partner closely with the CEO, VP Marketing and Heads of Product, helping shape strategy, drive design excellence, and ensure that design becomes a core differentiator for Proton. You will build, mentor and scale a high-performing, multi-disciplinary design organisation, embedding design thinking across the company.

What you will do
• Define and execute the strategic vision for design at Proton, bridging product and brand to deliver a unified and differentiated experience globally.

• Excellent stakeholder management skills, with the ability to work at executive level and influence across product, marketing, engineering and operations.
• Deep user-centred design mindset; strong portfolio showing end-to-end work (research → strategy → UX → UI → brand visuals).
• Skilled in designing for global audiences, with sensitivity to cultural differences and brand consistency across markets.
• Expertise in building and scaling design systems, establishing best practices and operational processes in fast-growing environments.
• Excellent leadership and people development skills: mentoring senior designers, creating high-performing teams, promoting a culture of craftsmanship and innovation.
• Comfortable working in a dynamic, high-growth company with a mission-driven ethos and a global, diverse team.
• Strong communicator with polished presentation and storytelling skills; fluent in English (other languages a plus).

What We Offer

• Work that Matters: Millions of people trust Proton with their privacy. We answer only to our users — not advertisers, not investors with conflicting agendas, not governments.

• Technology: The right hardware and software to do your best work.
• Learning & Development: We invest in your growth. Proton is one of the fastest ways to accelerate your career — real challenges, real ownership, from day one.
• Employee Benefits: Strong health coverage, solid retirement options, generous leave, and wellness support.
• Stock Options: From day one, you have a real stake in what we're building. When Proton wins, you win.
• In-Person Collaboration: Offices across Geneva, Zürich, Barcelona, London, and more. You'll spend most of your time collaborating face-to-face.
• Food: Lunch and snacks on us every day in the office.
• Transport: We cover public transport, bike allowances, or parking — whichever works for you.
• Flexible Working: You own your schedule. Outcomes matter more than clock-in times.

Our Commitment to Diversity and Inclusion

At Proton, we believe diversity drives innovation and strengthens our mission to provide privacy as a default for all. We are committed to fostering an inclusive environment where all individuals — regardless of race, ethnicity, gender, age, sexual orientation, physical ability, or socio-economic background — feel valued and empowered.
