Join Proton and build a better internet where privacy is the default.

At Proton, we believe that privacy is a fundamental human right and the cornerstone of democracy. Since our inception in 2014, founded by a team of scientists from CERN, we have dedicated ourselves to providing free and open-source technology to millions worldwide, ensuring access to privacy, security and freedom online.

Our journey began with Proton Mail, the largest secure email service globally, and has since expanded to include Proton VPN, Proton Calendar, Proton Drive and Proton Pass. These tools empower individuals and organisations to take control of their personal data, break away from Big Tech’s invasive practices and defeat censorship. Our work impacts hundreds of millions of lives, from activists on the front lines defending freedom to leaders in governments protecting sensitive information.

Proton is a profitable company that does not rely upon VC funding, supporting over 100 million user accounts with a growing team of over 500 people from over 50 different countries. We value intelligence, learning potential and ambition in our hiring process. Adaptability is key as we navigate uncharted territories and redefine how business is conducted online.

• Experience in leading cross-functional projects, coordinating across multiple teams to deliver complex solutions.
• Strong product engineering mindset, focusing on designing back-end systems that drive excellent user experience.
• Experience building scalable solutions, especially for systems that serve a wide variety of clients.
• Fluency in OOP and SOLID.
• Solid understanding of SQL (MySQL preferred) and data modelling.
• Good knowledge of unit and functional testing.
• Strong understanding of security best practices.
• Understanding of HTTP / REST, including both developing and consuming web-based APIs.
• Operational experience, such as SRE or on-call, demonstrating ability to diagnose and troubleshoot complex problems for critical systems.
• Experience with Docker or similar containerisation technologies.
• Experience with CI / CD (Gitlab, Jenkins, etc.).
• Experience with back-end web frameworks (Symfony, Spring, .NET).
• Experience with modern PHP, Rust and Python.
• High-level understanding of cryptography concepts such as key exchange and the difference between symmetric and asymmetric encryption.
• Experience with DDD (Domain-Driven Design) and other enterprise patterns.
• Experience with metrics graphing / analysis toolkits such as Grafana and OpenTelemetry.
• Solid understanding of Redis or other caching technologies.
• Experience with OpenAPI specs or other API documentation frameworks.
