Proton is one of Europe’s fastest growing scale-ups, serving more than 100 million users around the world.

Our mission is to build a more ethical and responsible alternative to Big Tech services, with a focus on end-to-end encryption, privacy, open-source and ease-of-use. Our user-first approach has helped Proton grow organically to serve millions of consumers and businesses around the world, with users from organisations including The Guardian, The New York Times and the UN.

We're headquartered in Geneva, Switzerland, with additional offices in Zurich, London, Paris, Barcelona, Taipei, Skopje, Vilnius and Prague.
As one of Europe's fastest-growing companies, we offer the chance to tackle complex challenges, influence millions and shape a more equitable internet.
