Om jobbet

About Us

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.
