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.

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.

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.
