How to Apply for Principal Java Developer (Angular/React)

at Eurofins

🏢 About Eurofins

Eurofins is a global leader in analytical testing services, operating in over 900 laboratories across 62 countries. The company's mission to promote safer, healthier, and more sustainable environments through scientific testing offers meaningful work with real-world impact. Working at Eurofins means contributing to critical testing services that affect food safety, pharmaceutical development, and environmental protection worldwide.

About This Role

As a Principal Java Developer at Eurofins, you'll lead the design and development of complex enterprise-scale Java applications while driving modernization initiatives from legacy systems to modern architectures. This role combines hands-on technical implementation with leadership responsibilities, requiring you to own technical direction for modules/subsystems while actively mentoring engineers across teams. Your work will directly support the company's digital transformation and global analytical testing operations.

💡 A Day in the Life

A typical day involves collaborating with global teams to design and implement Java-based solutions for analytical testing systems, balancing hands-on coding with architectural discussions. You might spend the morning reviewing pull requests and mentoring engineers on best practices, then transition to designing RESTful APIs or modernizing legacy components, followed by planning sessions for system migrations. The role requires constant context-switching between deep technical implementation and broader technical leadership responsibilities.
