Proton was founded in 2014 by scientists from CERN on the belief that privacy is a fundamental human right. Since then, Proton has built the world's largest encrypted email service and expanded into Proton VPN, Proton Drive, Proton Pass, and Proton Calendar, serving millions globally. Proton is profitable, independent, and hires selectively from the top ~1% of applicants. The team consists of 500+ members across 50+ countries, moving fast with a light hierarchy and prioritizing impact. Proton Drive is a secure, private cloud storage and collaborative editing suite with clients on Windows, Mac, iOS, Android, and Web. The Linux platform is missing, and you will build it from scratch in a greenfield project with high visibility inside Proton and across the open-source community.
Tasks
- Own the design and implementation of the Proton Drive Linux desktop client, built greenfield from the ground up.
- Ensure the codebase meets the standard expected of production open-source software, as it will be read and built upon by developers beyond Proton.
- Integrate deeply with Linux-specific system components, including the filesystem layer for the file synchronization engine.
- Contribute to the platform-agnostic SDK and CLI tooling to ensure Linux features are properly exposed for scripting and cross-client use.
- Build and maintain cross-client automated and end-to-end tests in collaboration with Windows and Mac engineers.
- Define and implement application telemetry to support performance analysis, debugging, and customer support.
- Own the build pipelines, packaging, and distribution across major Linux distros.
Requirements
- 5+ years of experience in software development of Linux-based desktop client software, both with and without a visible interface (GUI apps as well as CLI apps).
- Applied best practices in code quality paradigms.
- Experience with DevOps principles and practices (CI/CD, etc).
- Experience with source control flow through Git (code reviews, branching and merging, etc).
- Open-source Linux development, distribution, packaging and maintenance for multiple distros (e.g. on Debian or Fedora-based platforms).
- Handling the entire software development lifecycle, end to end.
- Nice to have: Experience in Linux desktop client development (in particular through the GTK+ framework, or alternatively Qt).
- Nice to have: Experience in Rust.
