• Partner with backup/recovery teams on policy, FlashCopy/Snap, DR readiness, and test execution.
• 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.
