As a Senior Mendix Developer, you play a key role in shaping the digital experience of more than 50,000 Jumbo colleagues. You will design, build, and continuously improve a large and complex Mendix landscape running on top of our new SAP S/4HANA platform. The applications you develop support critical store processes every day and make the work of thousands of colleagues easier and more efficient.
You take the lead in technical decision-making, safeguard the quality of our solutions, and ensure that applications remain reliable, scalable, and future-proof. You work according to the principle: You build it, you run it, you own it. From design and development to maintenance and support, you are responsible for the entire lifecycle of your solutions.
Within the Store Employee Experience team, you collaborate closely with Mendix Developers, testers, UX/UI designers, and business analysts. You also work with SAP specialists, AWS experts, and colleagues from other Mendix teams to deliver smart, integrated solutions that create real business value.
