Permanent position at Twoday | CopenhagenSitecore Developer (.NET)

Are you an experienced Sitecore developer who enjoys being close to the code and turning business needs into reliable digital solutions? Twoday is looking for a hands-on developer for a business-critical assignment with a large Danish public-sector organisation.

You will be permanently employed by Twoday, with your first assignment carried out full-time on-site at the client’s offices in Copenhagen.

The role

You will join a development team responsible for maintaining, improving and further developing the client’s Sitecore-based solutions. Your focus will be practical software delivery: writing code, troubleshooting, implementing integrations and ensuring that solutions perform reliably in production.

You may contribute to technical decisions and solution design, but this is primarily a hands-on development role rather than a pure architecture position.

Your responsibilities will include:

• Developing and maintaining solutions in Sitecore and C#/.NET

• Implementing new functionality and improving existing solutions

• Building and maintaining integrations and APIs

• Troubleshooting defects and resolving technical issues

• Contributing to testing, code quality, documentation and deployment

• Collaborating closely with developers, testers and business stakeholders

Your background

We expect you to have:

• Solid professional experience with Sitecore development

• Strong hands-on skills in C# and .NET

• Experience with integrations, APIs and web-based solutions

• The ability to understand and work confidently in an existing solution landscape

• A structured approach to quality, maintainability and documentation

• The confidence to take responsibility for tasks from clarification through to implementation

• An open and pragmatic approach to using AI-assisted development tools where relevant

Experience with Sitecore upgrades, deployment, performance optimisation or complex public-sector solutions would be an advantage.

Fluency in spoken and written Danish is essential, as daily collaboration and documentation take place in Danish. You must also be able and willing to work full-time on-site in Copenhagen.What we offer

At Twoday, you will become part of a strong professional environment where knowledge sharing, collaboration and technical quality are central. You will work on meaningful digital solutions while developing your skills alongside experienced colleagues.

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

Interested? We look forward to receiving your application.
