Mullvad VPN is a Swedish VPN company dedicated to fighting mass surveillance and censorship. We do this primarily through our VPN service and our privacy-focused web browser. Over the years, we have been pioneers when it comes to VPN technology and we intend to remain trailblazers. Everything we do is built with our users' security and privacy first - with the ambition of making mass surveillance and censorship impractical.
The Job
We're looking for a CI/CD engineer to join our app team at Mullvad. This team is responsible for developing and maintaining the apps for Android, iOS, Windows, macOS and Linux.
In this role, you will design, maintain, and secure the systems that build, sign, test, and deliver our products in cross-platform, and containerized environments. Our app and everything our team works on is open source and available on GitHub.
What you will do
Work at the intersection of automation, systems engineering, and software supply-chain security
Develop and maintain build scripts and workflows across multiple operating systems and toolchains
Manage code signing processes, signing keys, and secure build architectures
Set up and manage virtual machines, simulators, and environments for automated testing
Monitor, optimize, and troubleshoot CI/CD performance, reliability, and scalability
Who you are
Strong experience with at least one CI system (e.g. GitLab CI, GitHub Actions, Jenkins, Azure Pipelines)
Deep understanding of Linux systems; experience with Nix or NixOS is a strong plus
Hands-on experience with Docker and containerized build environments
Solid understanding of software signing processes, certificate/key management, and supply-chain security
Good communication skills in English
Humble and team-oriented mindset
Autonomous and self-starter
Now it would be ideal if you have experience with
Reproducible builds and deterministic toolchains
Android and iOS build tooling and emulators/simulators
Infrastructure-as-code tools (Terraform, Ansible, Nix flakes/modules, etc.)
Maintaining cross-platform toolchains for C/C++, Rust, Go, or similar languages
Why Mullvad?
We value quality over quantity and believe in good solutions rather than quick fixes. Our apps are open source, our teams are curious and collaborative, and we care deeply about removing bloat rather than adding it.
We are a group of different people: vegans and marathon runners, audiophiles, farmers, and coffee brewers. What brings us together is simple: we want to build technology that fights mass surveillance and censorship.
If you want to build products that make an impact, enjoy generous benefits, and work for a purpose you can stand behind, welcome to Mullvad.
