Full Stack Developer
NorthStar Systems builds software that handles and structures large volumes of data for law enforcement and national security organisations worldwide. These are not typical web applications — they are complex, data-driven platforms where reliability, performance, and traceability are non-negotiable.

We're looking for a developer who is comfortable across the stack but naturally leans toward the backend. You'll join a small, experienced team in Aarhus where ownership is the norm, responsibilities are shared, and problems are yours to solve from idea to implementation.

Role

Most of your work will live in the backend — ingesting, processing, and exposing data through APIs across a distributed, streaming architecture. Services are containerised and deployed via Docker and Kubernetes, with observability handled through Prometheus, Grafana, and ELK.

Tech environment

• Java, Spring Boot
• Kafka (data streaming)
• MongoDB
• Docker, Kubernetes
• Prometheus, Grafana, ELK (observability)

You'll occasionally take on frontend work to carry features across the finish line, and interact directly with international technical partners who build on top of the platform. There are no heavy processes or lengthy handover chains — decisions are made close to the code.

What makes this role worth your attention

Ownership is real here. You're not implementing predefined solutions — you're helping shape them. This is not a standard CRUD setup — it's a distributed platform with continuous data flows, multiple services, and real-world constraints that keep the work engaging. The team values pragmatic thinking over chasing trends, with room to explore new technology when it actually solves a problem.

What we're looking for

A solid backend background, ideally in Java or a comparable ecosystem, with experience in systems more complex than standard applications. Equally important: you don't define yourself too narrowly. You're willing to step outside your primary area, take responsibility for complete solutions, and collaborate closely to get things done.

Interested?

If you want to work on meaningful systems, take real ownership, and be part of a small, highly capable team - we'd like to hear from you. The hiring process is straightforward and designed to respect your time.
