Job Description/ Responsibilities

Own the IBM z/OS patch management strategy, including SMP/E maintenance (PTFs, APARs, RSU/CSI management) and subsystem patching (CICS, DB2, IMS, MQ, RACF, and related products).
Define the rolling patch and maintenance calendar in alignment with IBM service delivery cycles, security advisories, and enterprise change freeze windows.
Assess incoming IBM and ISV maintenance for applicability, risk, and priority; triage HIPER, security, and integrity PTFs for expedited handling.
Set technical direction for, and provide hands-on oversight of, an offshore mainframe operations team executing patch installs, regression testing, and validation across the z/OS estate.
Establish and enforce patching standards, runbooks, and quality checkpoints so offshore-executed work meets the same bar as work performed directly.
Review and approve patch testing results, rollback plans, and go/no-go decisions before production implementation, including for changes executed by the offshore team.
Coordinate with systems programmers, security, and application teams to plan patch windows and manage changes through the CAB process.
Track patch compliance across the mainframe estate; report on outstanding vulnerabilities, aging maintenance, and remediation timelines to management.
Serve as the primary escalation point for patch-related incidents, including issues surfaced by the offshore team during off-hours windows; lead root cause analysis and remediation.

We are an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex (including pregnancy, sexual orientation, or gender identity), national origin, citizenship status, age, disability, genetic information, protected veteran status, or any other characteristic protected by applicable law https://www.e-verify.gov/sites/default/files/everify/posters/IER_RighttoWorkPoster.pdf
