Easily commutable from Birmingham, Coventry & London

£55k – £65k + Corporate benefits

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.

Responsibilities:

  • Writing new Enterprise COBOL programs and enhancing existing ones, including embedded SQL against DB2
  • 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
