This role requires deep expertise in mainframe and AS/400 (IBM i) environments to lead and deliver the patch management program across complex legacy and hybrid infrastructure estates, develop automation solutions that reduce manual effort and risk, and serve as a trusted technical advisor to enterprise clients - working closely with client stakeholders, project managers, and cross-functional delivery teams to plan, schedule, and execute patch cycles while ensuring compliance, stability, and security across mission-critical platforms.

• Own the creation and execution of a technical execution plan for your domain - maintaining delivery commitments and proactively surfacing risks
• Provide hands-on technical design guidance to unblock infrastructure automation engineering: architecture decisions, integration patterns, implementation approaches
• Lead detailed design and drive execution of infrastructure test harnesses, infrastructure automation engineering, and deployment capabilities within your domain
• Lead technical decisions within your domain, ensuring solutions are standardized and production-scalable
• Drive PI planning, backlog prioritization, and sprint-level adjustments with engineering throughput as the primary success metric
• Coordinate with the Testing Platform team on infrastructure onboarding, test suite migration, and CI/CD pipeline integration
• Manage cross-domain dependencies and represent your domain's delivery status to program leadership and client stakeholders
• Develop junior team members through direct coaching, design reviews, and structured feedback

Patch Delivery - Mainframe & AS/400 Infrastructure

• Understand patch windows across development, QA, and production environments
• Maintain patch compliance dashboards and KPIs

Automation Engineering - Mainframe Environments

• Coordinate automation frameworks to streamline patch identification, scheduling, and deployment on z/OS and IBM i systems
• Design automation pipelines with enterprise tooling (e.g., IBM Tivoli, CA7, TWS/OPC, ServiceNow, SDSF) to reduce manual touchpoints
• Design automated compliance checks, health monitoring, and alert frameworks for patch-related activities
• Coordinate with DevOps teams to incorporate mainframe automation into CI/CD pipelines where applicable

Client-Facing Consulting

• Serve as a primary technical point of contact for client stakeholders across mainframe leadership, infrastructure, and security teams
• Lead requirements-gathering workshops and translate business objectives into infrastructure delivery roadmaps
