Senior PowerBuilder Developer

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.

Responsibilities: resolve complex PowerBuilder issues and share production maintenance duties; analyse application components and dependencies (Pbls, Powerscript, Pfc, Datawindows, Datastores); identify business rules, edge cases and redundant behaviour; decouple business logic from GUI controls and database access (Embedded SQL, dynamic SQL, stored procedures); work with analysts and business specialists to translate existing behaviour into functional and technical specifications; collaborate with Java/Angular developers on REST API contracts and validate regression coverage; build shared technical documentation, mentor colleagues and use static analysis and AI-assisted tools.

Requirements: at least 5 years of hands-on PowerBuilder development (PowerBuilder 8-2022 / Appeon), advanced Powerscript and Pfc knowledge, strong relational database and SQL skills (transactional SQL, PL/SQL, query optimisation), understanding of stateless REST APIs, MicroServices, Spring Boot, Angular and JSON DTOs, practical Java/Spring Boot and/or Angular experience or strong aptitude, analytical approach and clear documentation, French or Dutch plus professional English.

Why consider this role: a hands-on technical lead opportunity combining production continuity, knowledge sharing and modernisation. Oliver James is a global recruitment partner established in 2002.
