Description

• Lead z/OS platform modernization and upgrade engineering across multiple concurrent legacy and current z/OS versions, managing interoperability and incremental upgrade paths.
• Provide deep system-level engineering expertise across the core IBM Z stack, including DB2 for z/OS configuration, CICS TS workload tuning, IMS platform interaction, and IBM MQ Queue Manager architecture.
• Perform dependency validation across the full stack, pre-upgrade technical assessments, and post-upgrade stabilization/tuning.
• Provide engineering insight into mainframe storage behavior, layout, recovery, and networking protocols (including SNA, VTAM, and TCP/IP interactions) around z/VM virtualized environments.
• Review and engineer security profiles across RACF and ACF2 platforms to maintain access controls, compliance enforcement, and data-in-transit encryption.
• Leverage SMF, RMF, and operational metrics to analyze system performance, identify bottlenecks, tune system parameters, and support capacity planning.
