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.
