• Proficiency with monitoring and performance analysis (RMF/SMF, OMEGAMON, or similar).
• Familiarity with RACF/ACF2/Top Secret concepts, access models, and audit support.
• Solid understanding of ITIL processes and experience using an ITSM tool (preferably ServiceNow) for incident/problem/change.

• Exposure to z/OSMF, Ansible for z/OS, Zowe, or API-driven automation.
• Knowledge of networking on z/OS (TCP/IP stacks, VTAM/SNA, Enterprise Extender).
• Scripting/programming: REXX, Assembler basics, COBOL reading, Python on USS.
• Experience with capacity planning and cost optimization (MSUs, WLM policies).
• Background in regulated/enterprise environments (financial services, government, healthcare, retail).

• Platform & Infrastructure Operations Operate, maintain, and optimize z/OS LPARs, Sysplex, WLM, JES2/JES3, USS/OMVS, TSO/ISPF, SDSF. Install, configure, and maintain mainframe software using SMP/E and vendor best practices. Monitor and tune system performance using RMF, SMF, OMEGAMON (or equivalent), addressing CPU, memory, I/O, and throughput.
• Subsystem & Product Support (MF Application-Adjacent) Support and administer DB2 for z/OS, CICS TS, IMS (DB/TM), and IBM MQ: configuration, health checks, upgrades/maintenance, performance tuning, and high availability. Work with application teams for deployment validation, capacity estimates, SQL/CICS/IMS tuning, MQ channel/queue configuration, and resolving production incidents.
• 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.
