RPG Developer - Banking
Excellent opportunity to join a major UK bank, working on a critical core platform running on IBM i. This is a hands-on role for a genuinely strong RPG/IBMi engineer who can go beyond coding into system-level understanding, performance, and security.
You'll be working on a live, business-critical environment, owning development, enhancement, and support of key applications, with real visibility across both technology and business stakeholders.
* Design and develop high-quality RPG solutions (fixed and free format)
* Translate business requirements into technical design and user stories
* Work closely with architecture and business teams on new functionality
* Troubleshoot and resolve complex production issues using joblogs, journals, and OS-level tooling
* Evaluate and improve existing applications (performance, structure, maintainability)
* Contribute to Agile ceremonies (Show & Tell, sprint delivery, etc.)
* Produce technical documentation and user guidance
* Support critical systems, including occasional out-of-hours work
Strong, hands-on experience with:
* RPG development on IBM i
* Deep understanding of IBMi internals (not just coding)
* SQL (standalone and Embedded) with performance tuning capability
* Debugging and forensic analysis across joblogs, journals, and system logs
* Modern RPG techniques (modules, service programs, activation groups)
You should also have exposure to:
* System security concepts (authorities, user profiles, access control)
* Journalling, recovery, and audit mechanisms
* Performance tuning and system-level optimisation
* Agile delivery environments
Nice to have:
* Experience supporting critical, high-availability systems
* Exposure to Citrix or infrastructure-level considerations
