You will be a valued member of the Cloud Infrastructure and Security team and work collaboratively with the Senior Manager.
In this role, you will

Support z/OS version upgrades and core platform components, including Parallel Sysplex, JES2, LPARs, system parameters, Parmlib, and z/OSMF.
Monitor, analyze, and improve z/OS performance and capacity using RMF, SMF, WLM, and related reporting tools.
Perform IMS Version 15 system programming activities, including software installation, upgrades, maintenance, fixes, IMSGEN, and SYSGEN.
Administer and maintain IMS environments, including backup, recovery, reorganization, space management, data integrity, and restoration of corrupted data.
Support IMS database administration activities, including database objects, IMS and DB2 commands, IBM IMS utilities, SQL performance tuning, and database housekeeping.
Investigate and resolve incidents, problems, deadlocks, timeouts, and other performance or availability issues across z/OS, IMS, and related products.
Support security, change, and problem-management processes while contributing to technical documentation, proof-of-concept work, and continuous platform improvements.
Communicate technical risks, recommendations, and long-term improvement opportunities to technical leaders and stakeholders.

Proven ability to perform IMS Version 15 system programming activities, including IMSGEN, SYSGEN, software installation, upgrades, and maintenance.
Experience with IMS backup, recovery, reorganization, data integrity, space management, and IBM IMS utilities such as Backup, Reorg, Recovery, Load, Unload, and Pointer Checker.
Working knowledge of RDBMS concepts, IMS or DB2 commands, SQL, SQL performance tuning, and database monitoring.
