Description du poste

A better internet, where privacy is the default, is possible. Building this better internet might seem daunting or even unthinkable, but at Proton, this is what we do every day.

Proton was founded in 2014 by a group of scientists who met at the European Organization for Nuclear Research (CERN). Our first product, Proton Mail, is now the world’s largest encrypted email service. Subsequent Proton products, such as Proton VPN, Proton Calendar, Proton Drive, and Proton Pass give our users full control over how and with whom their data is shared.

Today, Proton makes privacy universally accessible. Journalists from outlets like The Guardian and The New York Times, some of the world’s largest organizations, and people in more than 180 countries have signed up for over 100 million accounts. Our diverse and dynamic team is made up of more than 400 members representing over 40 different nationalities. While we are based in Geneva, Switzerland, we have offices in Zurich, Prague, London, Vilnius, Skopje, Taipei, Barcelona, Paris and many more employees working remotely around the world.

Join one of Europe’s fastest-growing companies to help us solve challenging problems and build new products that will reach hundreds of millions of people. We want to create more than just one of the world’s most impactful tech companies; we want to create a new internet that serves the interests of all people. We need you, your voice, your ideas, and your ambition to make it happen.

What you will do:

• Architect and develop shared libraries: Lead the design and development of Rust libraries that will be shared across web and mobile applications.
• Code review and optimization: Conduct code reviews and provide constructive feedback to ensure code quality, maintainability, and performance optimization.
• Collaboration: Work with frontend and mobile developers to integrate libraries seamlessly into Proton's applications.
• Testing: Develop and implement comprehensive testing strategies, including unit tests and integration tests.
• Documentation: Create and maintain thorough library documentation to assist other developers in understanding and utilizing the components.

Job requirements:

• Experience: 3+ years of professional software development experience, with a focus on Rust programming language.
• Rust proficiency: Strong expertise in Rust language features, concurrency, and ownership model.
• Web and/or mobile development: Experience in developing libraries for both web and mobile applications.
• Collaborative skills: Proven ability to work collaboratively in a team environment and excellent communication skills.
• Problem-solving: Strong problem-solving skills and the ability to troubleshoot issues efficiently.
• Bachelor's or Master's degree: In Computer Science, Software Engineering, or a related field.

Bonus points for:

• Experience with DDD (Domain-Driven Design) and other enterprise patterns.
• Experience with web-assembly.
• High-level understanding of cryptography concepts such as key exchange and the difference between symmetric and asymmetric encryption.
• Experience with Docker or similar containerization technologies.
