  • Mature in the full software life cycle (product discovery, CI/CD pipelines, observability, configuration management, compliance etc)
  • Experience with Azure DevOps pipelines is a plus

Who you will work with

You are going to be part of a small team composed by two experienced software engineers and a Product owner. On Monday you will work at the office in The Hague and on Wednesday you will work from our Rotterdam office.

By the nature of the centralized solutions we create for NN Bank, you will interact with many other colleagues in different departments. Specially with other engineers and architects. As all our tech departments are international with English being the main language.
