- 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.

- 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.
