About This Role

As a Sr Java Fullstack Developer, you will own and drive the design and development of complex, enterprise-scale Java applications, leading technical direction for modules while remaining hands-on. Your work will directly support modernization initiatives, migrating legacy systems to modern architectures, and you will mentor engineers across teams, shaping the technical future of Eurofins' digital solutions.

💡 A Day in the Life

Your day starts with a stand-up with your team, discussing progress on migrating a legacy module to microservices. You'll spend the morning coding a new REST API in Spring Boot and reviewing a colleague's Angular component. After lunch, you mentor a junior engineer on design patterns, then profile a performance bottleneck using JProfiler. The day ends with a design session for the next sprint's architecture.
