Description du poste

About Corilus

Corilus is the leading provider of digital solutions for healthcare professionals in Belgium, with over 30 years of experience building software for doctors, pharmacists, nurses, and care coordinators. Today, we serve more than 70,000 healthcare professionals.

We are now at an inflection point. Following the acquisition of Sofia Dévelopement in France and backed by PSG and Rivean Capital, we are consolidating our portfolio into a unified, AI-native platform that will redefine clinical software across Belgium and France.

We are looking for builders — people who see the gap between what healthcare software is today and what it could be, and who want to close it.

About the Role

At Corilus, we believe technology only creates real value when it is combined with strong collaboration and a relentless focus on quality. Building great software is not just about writing code, it is about working closely with others, understanding real user needs, and delivering solutions that truly make a difference.

As a Senior Software Engineer Java / Spring Boot, you play a key role in a complex, challenging, and people-focused environment. You contribute to the development of impactful solutions used by healthcare professionals, working alongside product owners, analysts, and fellow engineers. You take ownership of your work, actively contribute to technical discussions, and help shape scalable, secure, and reliable systems.
