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.
