Senior Software Developer – build and improve features for our growing library solution

Are you an experienced software developer who has a keen eye for feature development? Do you like taking responsibility and contributing to solutions used daily across libraries and schools? Then this could be the right next step for you.

Take ownership and contribute to important feature development
As our new Senior Software Developer, you will play a key role in driving the development of new features for Cicero – a comprehensive library solution used in every Danish municipality as well as in Sweden, Norway and Germany.

You will be involved in designing, discussing and implementing new features that directly support library workers in their daily tasks and which help to ensure a coherent national and international library infrastructure.

In short, your key responsibilities include:

• driving the design and implementation of new features and improvements
• ensuring high code quality through reviews and inspections
• acting as a role model in coding practices and agile ways of working
• knowledge sharing and sparring with other developers

Join a growing team working on building library solutions for the Nordics and Germany
You will become part of an expanding department and join our team in Copenhagen. In cooperation with our committed and highly skilled group of 45+ colleagues – comprising domain experts and developers located in Aarhus, Copenhagen and Bucharest – you will accelerate the development and improvement of our library and learning solutions.

 
Bring your experience into play

We envisage that you have a relevant bachelor’s or master’s degree in computer science, software engineering or similar and several years of professional experience in a software company.

You bring a strong technical foundation and experience with:

• Java
• Jakarta EE
• SQL (MS SQLServer or PostgreSQL)
• IntelliJ
• Using AI tools in your daily work

Experience with any of the following is a plus, but not a requirement:

• Docker & Kubernetes
• Angular

• TeamCity

Beyond your technical skills, you enjoy collaboration, take ownership and naturally contribute to a positive team culture.
