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.

О роли

We are profitable and independent with no VC control. Our 500+ 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.

Чем предстоит заниматься

As an engineer on our small Windows VPN team, you will be responsible for designing, building, maintaining, and evolving Proton’s applications on Windows.

You will collaborate closely with product managers and engineers across the company to deliver privacy‑preserving products used by millions of people worldwide
Our codebase is primarily written in .NET and WinUI (C#/XAML), and we are building and integrating cross‑platform logical core libraries written in Rust
Software quality is central to this role. You will help define, maintain, and improve our testing stack, which includes unit tests, integration tests, and automated GUI tests (using FlaUI)

Наши требования

Strong experience in C# and .NET development
Strong experience building and maintaining Windows desktop applications using frameworks such as WinUI, WPF, or similar
Solid understanding of MVVM architecture, dependency injection, asynchronous programming (async/await), and event‑based messaging patterns
Proven ability to write maintainable, well‑tested, and scalable codebases
Demonstrated experience driving change within an organization and leading complex technical projects
A strong understanding of software architecture and engineering best practices
An appreciation for user experience and design quality
Rust experience is not required but is a significant plus
Working knowledge of networking fundamentals (TCP/IP, DNS, routing concepts) and an interest in VPN technologies and protocols
Experience with code debugging, profiling, and performance optimization on Windows
Familiarity with Git-based workflows, CI/CD pipelines (GitLab) and modern collaborative development practices
Experience with gradual rollout, and observability tooling (telemetry, metrics, monitoring and alerting)
Even if you don’t meet every requirement listed above, if you’re passionate about privacy and believe you could be a great fit, we encourage you to apply
