• Support critical banking systems in a high-availability environment
• Contribute to both BAU support and project-based initiatives

  • z/OS Systems Programming
  • System Automation (OPS/MVS, IBM SA)
  • CICS Transaction Server
  • DB2 for z/OS
  • IBM Z Storage (DFSMS, DASD)
• Solid understanding of core tooling such as JCL, TSO/ISPF, SMP/E
• Experience supporting production systems in enterprise environments
