Java Developer – Payroll Systems

Brugge (West Flanders) | Hybrid

I'm partnering with Liantis, a key player in HR & payroll services in Belgium, who are looking to strengthen their Gemini team with 2 experienced Java Developers.

This team supports a large, complex payroll landscape made up of multiple Java applications — some modern, some legacy, all business critical. This is not a greenfield role, but a chance to build deep expertise, bring stability, and make a real impact in systems used daily by thousands of people.

If you enjoy understanding how systems really work under the hood — this one's for you.

What You'll Do

• Maintain and enhance Java-based payroll applications
• Analyse and improve legacy Java code with limited documentation
• Build new features within existing platforms (no greenfield pressure)
• Troubleshoot production and functional issues
• Share knowledge and collaborate within a close-knit Agile team
• Gradually improve code quality, stability, and maintainability

Tech Stack

• Java 8+
• Spring Framework (Boot, Data, Web Flow)
• Hibernate / JDBC
• SQL
• JSF / PrimeFaces
• GitHub

Nice-to-haves: Docker, RabbitMQ, Azure, Maven, JUnit / Mockito

Why Liantis?

• Work on mission-critical payroll systems that truly matter
• Long-term role with ownership, depth, and stability
• Strong team culture focused on knowledge sharing
• Pragmatic Agile way of working
• Hybrid setup with regular in-person collaboration

Who This Is For

Developers who prefer meaningful systems over endless greenfield churn, enjoy solving complex problems, and want to become a trusted technical reference in a stable, long-term environment.
