- Monitor DB2-related batch processes, investigate data issues, and support database-related job execution and recovery activities.
- Perform job scheduling, restart, rerun, recovery, and dependency management for failed or delayed batch jobs.
- Work with enterprise job scheduling tools such as Control-M, CA7, Zeke, or similar platforms.
- Investigate batch abends, job failures, performance issues, data discrepancies, file-processing issues, and application failures.
- Coordinate with application development, database administration, infrastructure, scheduling, and business operations teams to restore service and resolve production issues.
- Identify recurring production issues, perform root cause analysis, and recommend permanent corrective actions to improve platform stability.
- Support on-call and off-hours production activities, as needed, for critical incidents and batch-processing cycles.
- Provide enhanced support and monitoring for month-end, quarter-end, year-end, and other high-volume processing periods.
- Create and maintain production runbooks, job schedules, escalation procedures, known-error documentation, and issue-resolution guides.
- Participate in change-management, release-management, and production-readiness activities for application and batch-processing changes.
- Ensure all production changes, incident actions, job reruns, and recovery activities are documented in accordance with client procedures.
- Collaborate with teams supporting hybrid mainframe and modernized applications, including Java-based integrations where applicable.

- Experience with incident management, production troubleshooting, root cause analysis, and permanent corrective-action planning.
- Ability to diagnose and resolve COBOL application issues, DB2 data issues, JCL errors, batch abends, and job-performance concerns.
- Experience supporting critical processing windows, including overnight, weekend, month-end, quarter-end, or year-end batch cycles.
