Software Engineer (Linux)

Job requirements

• 5+ years of experience in software development of Linux-based desktop client software, both with and without a visible interface (i.e., 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)
• Overall, handling the entire SDLC, end to end
• Proton is an office-first company. We expect you to spend most of your time in the office, and while we do offer some flexibility to work from home, we believe in-person collaboration helps us build the best products.

Nice to have

• Experience in Linux desktop client development (in particular through the GTK+ framework, or alternatively QT)
• Experience in Rust
