Backend Developer (Java/Kotlin)

What are you going to do?

Ready to work on software that operates at serious scale and directly impacts how global retailers run their stores every day? At Nedap Retail, we build backend systems that make life easier for thousands of store employees worldwide—and we’re looking for a Backend Developer (Java/Kotlin) to help us push this even further.

At Nedap Retail, you’ll work with international brands such as Hugo Boss, lululemon, and Under Armour on a platform that provides retailers with real-time visibility into their inventory. Millions of items are continuously scanned and processed, resulting in billions of database operations each year. All core processes — from receiving and counting stock to moving and selling products — run through our backend systems. That’s why we build fast, scalable, and reliable systems. If you enjoy solving complex problems and working on high-throughput systems with a strong focus on performance, data consistency, and resilience, this role will feel right at home for you.

As a Backend Developer (Java/Kotlin), you’ll play a key role in building and evolving the core platforms behind our products. From day one, you’ll work on meaningful, production-critical systems, designing and implementing robust backend architectures, developing APIs and services, and improving existing platforms that operate at scale.
