Job Title Internship: Java Performance Optimization in Microservices Job Description Assignment type: Internship Start date: February 2027 Assignment duration: 6 months Location: Veghel Education level: Bachelor / Master Desired study: Computer science, Software engineering or related field Language: Dutch / English 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.
