Senior Mendix Developer

As a Senior Mendix Developer, you build and improve applications used daily by thousands of Jumbo colleagues. You translate business requirements into smart solutions, take initiative in improvements, and ensure that applications remain stable, secure, and future-proof. In doing so, you look beyond technology alone and actively contribute to the development of the Mendix platform.

You build and manage Mendix applications that support important store processes. In this role, you work closely with developers, business analysts, UX/UI designers, testers, and stakeholders. You investigate issues, think along about the best solution, and translate ideas into working applications.

In addition to new developments, you continuously improve existing solutions. You identify opportunities to design processes more smartly, increase the quality of applications, and ensure stable performance. You also realize integrations with SAP, AWS, and other systems within the Jumbo landscape.
