A long-established software business is hiring a Senior COBOL Developer to maintain and support its core platform during a 4-5 years migration project. You will work on a substantial estate of mission‑critical COBOL applications running the business day to day, alongside an active programme of enhancements, regulatory updates and performance work.

* Owning batch JCL and online CICS transactions, including BMS maps and copybooks
* Code archaeology and data analysis across legacy modules
* Supporting release management and code promotion across environments
* Mentoring junior team members and helping shape technical standards
Your experience will ideally include:
* Multiple years of Enterprise COBOL or VS COBOL II on a real production estate
* Strong CICS, DB2 and JCL, with hands‑on VSAM
* Comfortable with copybooks, BMS maps and embedded SQL on z/OS
* Code management with Endevor, ChangeMan, SCLM or similar
* Pragmatic approach to legacy code, with the patience to read it carefully before changing it
