Twoday is looking for an experienced developer with strong Angular skills and experience with .NET to join one of our public-sector customers in Copenhagen.

The organisation is currently transitioning towards full-stack development teams. Angular remains a core technology and is an essential part of the role, while .NET is increasingly important as developers contribute across the technology stack. Looking ahead, the frontend technology landscape will also evolve, with a transition towards Blazor planned.

You will join an established development environment working on business-critical solutions used by professional users. Your initial focus will be frontend development, while contributing increasingly across the full stack.

• Translate complex business requirements into intuitive and accessible user experiences

• Develop and integrate REST APIs

• Write automated tests and ensure high code quality

• Participate in code reviews, technical discussions and solution design

• Collaborate closely with developers, testers and business stakeholders

• Contribute to CI/CD pipelines and continuous improvement of development practices

• Potentially contribute to the future transition towards Blazor

Your background

• Strong professional experience with Angular and TypeScript – Angular is a requirement

• Experience with C# and .NET

• Ideally, a frontend-first full-stack profile or a strong interest in working increasingly across the full stack

• Experience with REST APIs and automated testing

• Familiarity with Azure DevOps, Azure Pipelines and YAML

• Experience with OpenAPI and Dapper is an advantage

• Experience with Blazor is an advantage, but not a requirement

• Experience from complex enterprise or public-sector solutions is an advantage

• Fluent spoken and written Danish is a requirement

• Able to work full-time onsite in Copenhagen
