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.\nIn 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\nDepartment description\nThis 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.\nWES 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.\nTasks/responsibilities\nAnalyze memory consumption of Java microservices running on Kubernetes \nProfile Spring Boot services to locate high memory usage \nExplore optimizations like JVM tuning, cache reduction, and GraalVM \nBuild proof-of-concept implementations to test improvements \nMeasure performance and savings before and after optimizations \nPresent results, practical recommendations, and expected cost benefits \nYour profile\nBackground in Computer Science or Software Engineering \nGood knowledge of Java and microservice concepts \nInterest in performance tuning, profiling, and optimization \nBasic experience with Linux, Spring Boot, or containers \nAn analytical mindset and strong communication skills \n*Mandatory enrolment to a Dutch Education System & resident of The Netherlands \nWhat we offer\nA monthly internship allowance (based on a 40-hour work week): \nBachelor: €500 per month \nMaster: €550 per month \nFull commuting allowance, including public transport, depending on whether you have access to free public transport or not \nOn-site health center with gym \nActive employee communities and initiatives \nExcellent company restaurant and barista coffee bar \nContact\nDo you recognize yourself in this challenging profile?
