About the Challenge

Being passionate about technology, you’d like to actively contribute to Belfius’s cloud transformation. You understand like no other that to deny the importance of cloud computing in this day and age, is to have one’s head in the clouds. You’re passionate about innovation, technology and disruption, and an experienced Java Developer, looking for your next challenge.

The IT landscape at Belfius is undergoing a metamorphosis. The mission of our Technology department is to manage all technological evolutions and to realise important projects from a cloud perspective. For instance, building a new technology platform, a future-proof data platform, and developing ground-breaking mobile apps. To support the realisation of these projects, we’re looking for experienced Java developers.

As a Software Engineer, you’ll be actively contributing to developing solutions and implementing components, processes and services. You will translate the functional requirements into future-proof solutions according to the agile methodology.


Your skills

These will be your tasks:

  • Analyse, develop, integrate and test new applications and frameworks
  • Manage, maintain and evaluate applications and suggest optimisations
  • Participate in setting the standard for API development in the cloud
  • Act as a coach for fellow software engineers with different backgrounds; support users where needed
  • Rely on your experience with DevOps to quickly understand the nature of operational issues and provide solutions using new processes and tools
  • Keep up to date with the latest evolutions in the field and share your knowledge with co-workers
  • Ensure the stability of the production environment

To convince us you’re up to the task, we expect you to:

  • Hold a Bachelor’s or Master’s degree (preferably in Informatics, Engineering, Sciences, or Business Engineering)
  • Have at least 4 years’ experience as a Java Software Engineer
  • Demonstrate extensive knowledge of the Spring Boot framework, REST API design, clean code, unit testing, code reviews, technical documentation, and best practices in distributed systems such as monitoring/alerting, performance, service level agreement, and API metrics
  • Have experience with cloud environments (Azure) – with our 9-week paid traineeship you’re off to a good start!
  • Have experience with containerised applications (Docker, Kubernetes) and Infrastructure-as-Code (Azure DevOps pipelines)
  • Communicate easily with both technical and non-technical profiles
  • Speak English fluently, as well as Dutch or French

In return, we provide a myriad of new projects to ensure that you can optimally develop and use your skills and talents. We respect your work-life balance because that’s the only way you like to keep working. You choose how you fill your day, when you start or how long your lunch break is. You combine working from home with coming to the office near the Brussels-North train station. There, you’ll find a fitness room, a restaurant and cosy meeting places for a chat with colleagues.
