Production Control & Scheduling

• Manage workload automation and batch scheduling with tools such as Control-M, CA-7, ESP/Autosys, or equivalent; ensure batch SLAs and critical path adherence.
• Troubleshoot JCL, dataset management, procs, condition codes, and abends; perform restart/recovery and reruns.
• Improve job streams for efficiency and reliability (dependency modeling, calendars, alerts, event-driven triggers).

Storage Management

• Administer DFSMS (ACS routines, storage groups/classes), DFSMShsm (HSM policies, space management, migration/recall), and Catalog/ICF management (IDCAMS).
• Manage DASD and tape subsystems (e.g., DS8000, TS7700), volumes, VTOCs, data sets, and replication.
• Partner with backup/recovery teams on policy, FlashCopy/Snap, DR readiness, and test execution.

Reliability, Security & Compliance

• Implement and maintain RACF/ACF2/Top Secret security controls; support audits and compliance (SOX, PCI, ISO, etc.).
• Participate in BCP/DR planning, testing, and documentation.
• Apply SRE/operational excellence practices: error budgets, toil reduction, problem elimination, and automation-first mindset.

ITSM & Change Management

• Drive incident, problem, and change processes (e.g., in ServiceNow): root cause analysis, post-incident reviews, and controlled deployments.
• Author and maintain runbooks, SOPs, architecture diagrams, and knowledge articles.
