Job DescriptionRole SummaryOperates, administers, programs, or migrates data on IBM Z/OS mainframe systems and adjacent legacy technologies (CICS, IMS, DB2, ADABAS). Covers the full spectrum from production job operations to senior systems programming/DBA work to legacy data conversion for modernization projects. This talent pool is shrinking industry-wide - treat as a standing sourcing priority, not a reactive one.
Core Responsibilities- Start, stop, and monitor mainframe system tasks and subsystems (transaction processing, database systems, OS)
- Perform orderly shutdown/startup ('restart operations') of production workloads
- Plan, install, configure, and upgrade Z/OS systems and core system software products
- Administer and tune hierarchical (IMS), relational (DB2), and file-based (ADABAS) databases
- Develop, debug, and maintain mainframe application code (COBOL, NATURAL, Assembler, REXX)
- Support data mapping, crosswalk analysis, and validation during legacy-to-modern data conversion
- Manage production job scheduling and troubleshooting (Control-M, JCL, Endevor)
- Maintain detailed documentation and ticketing records for audits and knowledge continuity
- Facilitate knowledge transfer/training to build succession depth on an aging skill set
RequirementsSkills Required- Z/OS, CICS, IMS, DB2, ADABAS, ACF2, ENTIREX, SMP/E
- COBOL, NATURAL/SuperNatural, Assembler, REXX
- JCL, Control-M, CA Spool, TSO/ISPF, Endevor
- VTAM, TCP/IP, NetView, Tivoli
- Data conversion/ETL between legacy and relational/modern platforms
- Ticketing and production-control tooling (Cherwell or similar)
Experience Required- 5-7 years of experience in mainframe operations, systems programming, or application programming (role-dependent)
- For senior/lead roles: 3-5 years in a lead capacity
- 2-3 years working with legacy and relational data technologies (DB2, FOCUS, Oracle, SQL Server) for conversion-focused roles
- 1-2 years of automation of system monitoring/maintenance procedures for operator-tier roles
Education / Training- Bachelor's degree in an IT-related field or equivalent mainframe-operations experience
- Additional qualifying experience may substitute for education on a year-for-year basis
