Role Overview

The Mainframe WebSphere MQ & z/OS Systems Programmer is responsible for supporting, maintaining, and upgrading enterprise‑scale mainframe environments across high‑availability, 24x7 operations. This role ensures stability, security, and performance of WebSphere MQ on z/OS, while also contributing to broader mainframe systems programming activities including RACF security, automation, storage, monitoring, and subsystem upgrades. The ideal candidate brings deep hands‑on experience in complex, multi‑LPAR environments and has supported major financial institutions and large enterprise clients.

Key Responsibilities

  • WebSphere MQ Administration (z/OS)
    • Support, maintain, and troubleshoot WebSphere MQ on z/OS.
    • Plan and execute MQ upgrades (e.g., WMQ V7.0.1 V7.1.0).
    • Design and implement MQ health‑check tools (Rexx, CLIST).
    • Integrate MQ with automation tools such as CA‑OPS/MVS and SA z/OS.
    • Configure MQ security using RACF, ACF2, or Top Secret.
  • Mainframe Systems Programming (z/OS)
    • Install, customize, and upgrade z/OS and related subsystems.
    • Perform SMP/E maintenance, rebuild SMP environments, and manage toleration maintenance.
    • Configure and support CICS, IMS, VTAM, TCP/IP, and other core subsystems.
    • Manage DASD, tape systems, DFSMS, DFSMShsm, and storage utilities.
  • Security & Compliance
    • Review and enhance RACF/ACF2/TSS profiles.
    • Implement mainframe security frameworks for regulated industries (banking, insurance).
    • Conduct audits and produce security reports for compliance (OCC, regulatory bodies).
  • Automation & Monitoring
    • Implement and customize automation environments (SA z/OS, CA‑OPS/MVS).
    • Install and configure monitoring tools (OMEGAMON, TMON, MainView).
    • Develop automation exits and scripts to improve system reliability.
  • Programming & Tooling
    • Develop Rexx, Assembler, CLIST, PL/I, COBOL utilities for system automation and reporting.
    • Create JCL for backups, migrations, and maintenance tasks.
    • Build custom tools for performance tuning, forecasting, and operational reporting.
  • Client Support & Delivery
    • Work directly with enterprise clients (banking, telecom, insurance).
    • Provide technical leadership, knowledge transfer, and hands‑on demos.
    • Support multi‑national environments with high‑volume transaction workloads.
