Arbetsbeskrivning

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.

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.

• 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

• 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

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.
