Original job description

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.

Responsibilities

Own the z/OS patch strategy and maintenance calendar, assess and prioritize IBM and ISV updates, and oversee patch installation, testing, and validation across the mainframe estate. Coordinate production approvals and change windows, track compliance and vulnerabilities, and lead escalations and root cause analysis for patch-related incidents.

Requirements

The role calls for strong IBM z/OS and mainframe subsystem maintenance expertise, including MQ and RACF, along with experience managing SMP/E maintenance and security or integrity patches. It also requires technical oversight of an offshore operations team, patch testing and rollback review, change coordination, compliance reporting, and incident escalation.
