Experienced Backend Developer at IST

IST develops software for the education sector across Scandinavia. In Denmark, our system Studie+ handles student administration for vocational colleges, upper secondary schools, AMU, FGU and VUC. It’s a business-critical platform where data quality matters every single day.

We’re now looking for a senior backend developer to take ownership of development and data quality in Studie+. You’ll work in Java Spring Boot and PostgreSQL, act as the team’s database expert, and play a key role in migrating data from other systems into our platform. Like the rest of the team, you’ll use AI tools as a natural part of your day, for coding, reviews and documentation. We don’t expect you to be an expert, just curious and willing to make the most of them.

Your responsibilities

• Developing REST services in Java Spring Boot, deployed on Tomcat
• Designing and maintaining data structures in PostgreSQL, acting as the development team's go-to database expert
• Critically reviewing SQL and migration scripts
• Contributing to data migration projects from external sources
• Contributing to the CI/CD pipeline and the containerisation of services

What we expect from you

• Solid, proven experience with Java Spring Boot and REST services
• Strong PostgreSQL/SQL skills, including experience in quality-assuring other developers' SQL and migrations
• Experience designing and maintaining data structures in a production environment
• Familiarity with Tomcat as an application server
• A security-first mindset built into your solutions

Nice to have

• Experience with Docker
• Experience with TeamCity (CI/CD)
• Experience with Gradle
• Experience with SOAP integrations

Educational background

A Professional Bachelor's degree in Software Development, a Bachelor of Engineering, or an MSc in Engineering or Computer Science. As this is a senior position, however, we place greater weight on proven hands-on experience with Java, PostgreSQL and data migration than on any specific degree.

Experience

We are looking for a senior, experienced profile, typically with 5+ years of relevant experience.

Location

Our office in Central Funen (Midtfyn), Denmark. For the right profile, working from one of our other offices may also be an option.

What we offer

This is a full-time, permanent position. At IST, we apply an office-first policy, meaning we primarily work from the office as we believe physical presence fosters collaboration, innovation, and a strong team spirit. At the same time, we understand the importance of flexibility, if you live farther away, working from the office three days a week with the remaining time remote may be possible.
