Description of assignment 

Ready to tackle a high-impact software challenge? Our warehouse automation platform relies on dozens of Java and Spring Boot microservices on Kubernetes, where many services consume 600 MB to 900 MB per pod. High memory usage increases infrastructure costs, reduces cluster density, and limits scalability across development, testing, and production.  

In this project, you will investigate, measure, and optimize memory consumption across Spring Boot, Hibernate, JVM structures, thread pools, and caches without sacrificing performance or reliability. You will explore smart reduction strategies, answer how to minimize the platform's footprint, and deliver proof-of-concept optimizations with proven cost and resource savings 

Department description 

This assignment takes place within Warehouse Execution Systems (WES), the software development organization responsible for a key part of the Warehouse Platform. Our multidisciplinary teams develop and maintain different software modules in close collaboration. You will join an experienced and supportive environment where colleagues actively share their knowledge and help junior team members grow.  

WES offers a dynamic yet structured workplace where teams solve real-world challenges and continuously create and improve solutions. As an intern, you will work closely with a dedicated supervisor while collaborating with experienced software professionals who will support your learning and development throughout the assignment.
