We are seeking a CICS System Programmer to administer, support, and optimize enterprise IBM CICS environments. This role focuses on CICS platform stability, availability, performance, configuration, and system-level troubleshooting, rather than application development.
Roles and Responsibilities
* Ensure CICS production and test regions are stable, available, and operating efficiently.
* Monitor system health, performance, and capacity, and proactively address availability risks.
* Install, configure, maintain, upgrade, and patch CICS Transaction Server (CICS TS) environments.
* Manage CICS regions, startup parameters (DFHSIT), resource definitions (RDO), and system configuration settings.
* Perform CICS version migrations, upgrades, and PTF maintenance.
* Monitor transaction performance, CPU utilization, storage usage, and system metrics.
* Troubleshoot performance issues, abends, dumps, logs, and traces to identify root causes and implement fixes.
* Provide production support and resolve complex CICS system-level incidents.
* Work with security teams to manage secure access to CICS resources using RACF.
* Support CICS integration with DB2, MQ, IMS, TCP/IP, and web services.
* Support CICS environments operating across Sysplex and distributed environments.
* Maintain accurate system documentation, configuration records, and operational procedures.
* Follow established ITIL and change-management processes for system changes and production support.
Required Qualifications
* 5+ years of experience working in IBM z/OS mainframe environments.
* Strong hands-on experience with CICS Transaction Server (CICS TS).
* Experience installing, configuring, maintaining, upgrading, and patching CICS.
* Experience managing CICS regions, DFHSIT parameters, RDO resource definitions, and startup configurations.
* Strong troubleshooting skills involving system dumps, logs, traces, abends, and performance issues.
* Experience with CICS performance monitoring and tuning tools.
* Strong understanding of mainframe system operations and infrastructure.
Preferred Qualifications
* Experience supporting Sysplex environments.
* Familiarity with monitoring tools such as OMEGAMON, MainView, or TMON.
* Experience integrating CICS with DB2, MQ, IMS, TCP/IP, and distributed systems.
* Knowledge of mainframe security and RACF.
* Automation or scripting experience using REXX, Python, or Shell.
* Experience supporting large-scale enterprise or financial services environments.
