at Eurofins

🏢 About Eurofins

Eurofins is a global leader in analytical testing services, dedicated to promoting safer, healthier, and more sustainable environments. With a vast network of laboratories and a commitment to innovation, it offers a unique opportunity to contribute to impactful projects that directly affect public health and environmental quality.

About This Role

As a Senior Java Developer at Eurofins, you will design and maintain enterprise-scale Java applications, lead technical direction for key subsystems, and drive modernization initiatives from legacy to cloud-native architectures. Your work will directly support Eurofins' mission by enabling robust, scalable solutions for analytical testing data management.

💡 A Day in the Life

Your day might start with a stand-up meeting with your product and QA teams to align on sprint goals, then dive into designing a new REST API for a laboratory data ingestion module. After lunch, you could review a pull request from a junior developer, provide feedback, and later troubleshoot a performance issue in a legacy system, collaborating with the DevOps team to optimize cloud resources on Azure.
