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.
Proton is a privacy-focused technology company known for its encrypted email service Proton Mail, along with Proton VPN, Proton Drive, Proton Calendar, and Proton Pass. Founded by scientists who met at CERN, the company is headquartered in Geneva, Switzerland, and operates as a non-profit foundation structure, with a mission to build an internet that respects privacy. Proton has grown to serve over 100 million users worldwide, making it a significant player in the privacy tech industry.
In Spain, Proton has established a growing engineering and product presence, particularly in Barcelona, where it hires for roles such as Senior Android and iOS engineers, engineering managers, and test automation engineers. The company's work culture emphasizes privacy, security, and open-source values, and it is known for its remote-friendly policies and international team. For international professionals, Proton offers the opportunity to work on products used by millions, with a strong focus on user privacy and a collaborative, mission-driven environment.
Proton's Design team shapes the visual and interaction layer across Mail, Drive, VPN, Pass, and Calendar - products used by millions of people, many of whom rely on them in high-stakes moments. We work at the intersection of security and simplicity: our products must inspire trust without feeling intimidating, and feel refined without sacrificing clarity. Designers are embedded within engineering teams and involved from the very beginning - problem framing, planning, implementation, and quality assurance - not brought in at the mockup stage. The team is organized as a guild: high autonomy, shared standards, and real influence over how design is practiced across Proton.
We hold a high craft bar. Typography, layout, spacing, color, iconography, motion - the details most companies treat as polish, we treat as the product. If your best work is the work itself - pixels you're proud to sign - you'll be in good company here.
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.
