Do you want to work with advanced backend development in a product company where technical decisions are made close to the developers? At Silobreaker, you will become part of an experienced team building a world-class platform for cyber and environmental analysis – used by some of the world's largest companies and organizations.

About the role

As a backend developer, you will work with the core of Silobreaker's platform. Together with an experienced development team, you will develop and improve the backend services that handle large amounts of data and drive the product around the clock.

At Silobreaker, you will get to help solve technically challenging problems while having significant influence over how the solutions are designed. They work closely together and believe in knowledge sharing through, among other things, code reviews, pair programming, and technical discussions.

You will, among other things, work with:

  • Backend development in C#/.NET
  • Design and further development of scalable backend solutions
  • Code review, testing, and continuous improvements
  • Agile development work with sprint planning, demos, and retrospectives
  • Close collaboration with other developers and the product team

  • An academic degree in computer science, information systems, engineering physics, or similar
  • Good problem-solving skills and a genuine interest in technology

  • Like to collaborate and share knowledge
  • Are curious and like to learn new technologies
  • Take responsibility for the quality of what you build
