Occupation

Mainframe Developer

A Mainframe Developer designs, writes, and maintains legacy enterprise applications that run on IBM mainframe systems, commonly supporting large-scale batch processing for banking, insurance, and government organizations. The role centers on writing and debugging code in COBOL, managing batch job execution through JCL, and working with DB2 databases and CICS transaction processing systems. These developers often also perform Mainframe Systems Administration tasks and tend to be experienced IT professionals, since mainframe expertise is a specialized and increasingly scarce skill set.
