Senior Full-Stack Developer

Salary Competitive


Do you like working on accessibility? Then come join the Accessibility team as a Senior Full-Stack Engineer.

We collaborate, we learn, we challenge each other, we have fun, and we deliver. We are proud of our engineering culture and community spirit. We're in the middle of Copenhagen and we are from all over the world.

But there's more!

What you will be doing

You will be collaborating closely with the rest of your team, which includes all roles involved in bringing our products to our customers (e.g. UX, QA, PO, and engineers). As a developer we expect you to take responsibility for our engineering work along with the others on the team. You can be driving technical refinements and code reviews, continuously planning improvements of our code stack and tooling, mentoring more junior engineers, and so on. You are also encouraged to participate in cross-team collaborations helping us move forward as a department.

Product teams own both the front-end which our users interact and the back-end systems producing the data presented to our users, so experience in both front-end and back-end systems is a plus although not a necessity.

Our department is a mix of back-end, front-end, and full-stack developers, and we make sure the skillsets in each team complement each other well. On a product team, you will spend most of your time working on either new or existing user-facing features, so we also expect you to care about users and the problems we want to solve for them.

  • Write code for our accessibility rules engine in Typescript

  • Collaborate closely with the rest of the team on new product features using scrum methodology
