You are the craftsman behind our most robust backend applications! Within our passionate technical teams, your mission is to design and develop custom, high-performance, and scalable solutions based on the Java ecosystem. On a daily basis, you will:
Design and develop high-performance web applications and backend microservices using Java and the Spring Boot framework.
Create and integrate secure RESTful APIs to seamlessly connect our various platforms and services.
Guarantee code quality by writing unit and integration tests, and actively participating in peer Code Reviews.
Optimize application performance and handle complex modeling and queries for databases (SQL and/or NoSQL).
Deploy solutions following DevOps and CI/CD best practices (Docker, GitLab CI).
Participate actively in Agile ceremonies (Scrum) and collaborate closely with architects, Product Owners, and front-end developers.
Holding a degree in IT or computer science, you have at least 3 years of successful experience in Java backend development, ideally within a digital agency or IT services environment.
You have a perfect mastery of Java (recent versions) and its flagship ecosystem, particularly the Spring framework (Spring Boot, Spring Security, Spring Data).
You are comfortable with modern software architecture principles (microservices, event-driven architectures) and version control with Git.
You have a strong Clean Code culture, rigorously apply SOLID principles, and are convinced of the absolute importance of automated testing.
Endowed with a true team spirit, you enjoy sharing your technical knowledge, mentoring junior developers, and learning from the community.
Your technological curiosity, autonomy, and desire to push the boundaries of open source make you the ideal candidate. Fluency in English (French or Dutch is a great asset in Brussels) is essential to collaborate effectively.
