Senior Java Developer – Create Innovative Sales Solutions

Imagine yourself

• Working back-end on solutions that ease the buying experience for our customers
• Developing 'talk of the town' solutions such as the digital Rejsekort and 'Check ind' on DSB app
• Utilizing modern technology and methodologies such as Azure, Kubernetes, domain-driven design, and much more

We are looking for a Java Developer to join our quest.

We have recently introduced a tech lead role within our teams. For the right candidate, such a position could be relevant.

"By contributing to the enhancement of the Check Ind solution, I feel that I am making a difference to the public.

In the early stage, only a few customers used it. We have identified development areas, and now, more and more people use it because it's much more convenient, and in the future, we will add even more functionalities,' says Yao, Java Developer.

Join IT Sales Solutions
In IT Sales Solutions we are approximately 30 people: developers, testers, scrum masters, and external consultants, working in six different teams. You will join one of these teams.

We are a diverse group of engineers, IT specialists, and computer scientists, with all levels of experience ranging from new graduates to those having developed systems for decades.

Back-end systems are our main area: supporting the DSB app, dsb.dk, and our ticket vending machines.

'What I like best about the team is that we truly work and finish things together. We code, review, exchange opinions, communicate, share knowledge, learn, and improve ourselves and each other,' as Yao puts it.

A typical day for a Java developer in IT Sales Solutions
If you favour coming in early, you might start the day by coding in the morning. Sometime after 9 a.m., we have a short stand-up meeting, 15-30 minutes where we share updates on our current tasks, problems, findings, and time estimates.

The workday proceeds with e.g., reviewing pull requests, and providing or receiving feedback on our colleagues' work.

We put a lot of emphasis on cooperation and communication within and with other teams.

Many of us often work 1-2 days a week from home. But you're welcome to work from the office daily if you prefer.

Yao started in IT Sales Solutions in December 2023, straight out of university, she gives her perspective on the job,

'I get to use theory, algorithms, knowledge, and various coding styles, and apply them to solve real-world problems. It's super nice!'
