• Develop and maintain Sitecore-based solutions
• Contribute to broader backend development in C# and .NET

• Contribute to technical design and modernisation initiatives
• Write automated tests and participate in code reviews
• Work with CI/CD pipelines and deployment processes
• Collaborate closely with developers, testers and business stakeholders

Your background

• Solid professional experience with Sitecore development
• Strong hands-on skills in C# and .NET
• Motivation to work with both Sitecore and other .NET-based solutions
• Experience with integrations, REST APIs and relational databases
• Familiarity with automated testing and CI/CD
• Experience with Azure and Azure DevOps is an advantage
• Experience from complex enterprise or public-sector solutions is an advantage
• Fluent spoken and written Danish
• Able to work full-time onsite in Copenhagen

What we offer

At Twoday, you will join a strong professional environment focused on collaboration, knowledge sharing and technical quality. You will work with a varied system portfolio and have the opportunity to broaden your skills beyond Sitecore while contributing to meaningful digital solutions.

The position is a permanent role at Twoday, working full-time onsite with one of our public-sector customers in Copenhagen.

If you are the candidate we are looking for, you will play a central role with exciting opportunities to grow within an international and innovative group, working on cutting-edge technology and software solutions. You will also have the flexibility to occasionally work from one of our main offices in Oslo, Stockholm, Copenhagen, Helsinki or Vilnius.
