Over deze functie

**Senior PowerBuilder Developer**

Technical leadership and application modernisation

Brussels \* Hybrid \* 3 days on site per week

Contract options: permanent, fixed-term or freelance | Start: as soon as possible

About the role

Help shape the next chapter of a **business-critical application**. You will combine **hands-on PowerBuilder** development and production support **with technical leadership**, preparing an established client/server platform for a progressive **transition to Java and Angular.**

The role connects existing application knowledge with future development: understanding how the system works, making its business rules explicit and helping developers carry them into the new platform.

Your responsibilities

* Resolve complex PowerBuilder issues and share production maintenance duties, following agreed support and documentation practices.
* Analyse application components and dependencies, including PBLs, PowerScript, PFC, DataWindows and DataStores.
* Identify business rules, edge cases and redundant behaviour; separate functional requirements from interface logic and historical workarounds.
* Decouple business logic from GUI controls and database access, including embedded SQL, dynamic SQL and stored procedures.
* Work with analysts and business specialists to translate existing behaviour into clear functional and technical specifications.
* Collaborate with Java/Angular developers on REST API contracts and validate regression coverage through characterisation and Golden Master tests.
* Build shared technical documentation, mentor colleagues and use static analysis and AI-assisted tools to maintain traceability between code and specifications.
