At Umain, we build digital products that millions of people use.
Our motto is Shape, Ship, Scale: we work out what to build, ship it, and help it grow. Now, we are looking for a senior web
developer to join us in Gothenburg.
We like being in the same room, so this role is mostly on-site, with flexibility when you need it.
The work
You will build web products for Swedish and international clients, end to end. Most of our work is in JavaScript and TypeScript,
often with Next.js, React or Node.js, and we pick the tools that fit each project rather than forcing one stack onto everything.
You own systems end to end and work closely with product, design, analysis and testing rather than in a silo.
What we are looking for
You are an experienced web developer, roughly five years or more building and running things in production, who is comfortable
owning an application from start to finish. You are strong in TypeScript and happy to pick up other languages as projects demand.
You make good technical calls in a team: weighing tradeoffs, reviewing code, mentoring colleagues. And you think past the ticket
in front of you to maintainability and long-term health.
In consulting the next project rarely looks like the last one. If that sounds like a feature rather than a risk, you will fit in
well.
If you do not tick every box, apply anyway. We care more about how you think and what you can do than about a perfect match on
paper.
How we work
well you negotiate. You build your development plan together with your coach.
outside work as normal, not as something to manage around.
Practical
Umain conducts a background check for final candidates in accordance with our internal policies. The check is carried out only
with your consent and is ordered by our CISO through our approved screening partner. The scope of the check depends on the role
level. This step is performed late in the recruitment process and is used solely to support a secure and fact-based hiring
decision.
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 Senior Developer to join our Relay Software Team at Mullvad. This team is responsible for all custom software solutions used on our VPN relays. You'll play a key role in advancing server support for technologies such as Quantum-secure tunnels, traffic-analysis protection and protocol obfuscation. Who Are You You're someone who enjoys working in a team, contributes ideas proactively, and has a strong interest in security, networks and low-level software development. You value quality, maintainability, and thoughtful software design. You are curious and eager to learn, and you understand the importance of digital privacy. Responsibilities Work on new and exciting technologies and greenfield projects. Using Go, design and implement robust server software for running on Linux. Author clean solutions that balance performance and resource usage. Perform measurements, testing and troubleshooting. Coordinate with stakeholders and developers in other departments. Qualifications Excellent written and spoken English and Swedish. Highly developed understanding of software design and all aspects of software implementation. Experience with building server software. Excellent understanding of networking fundamentals. Strong knowledge in at least one of C/Go/Rust. 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 bunch of diversified peeps: from vegans to marathon runners, audiophiles to farmers and coffee brewers. So, what unites us? Our commitment to living and breathing our mission, to make mass surveillance and censorship impractical. 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.
