As a Domain Tech Lead on the AI & Engineering Hybrid Cloud Infrastructure team, you will own end-to-end technical delivery within a specific infrastructure domain on a large-scale infrastructure engineering engagement, with a focus on automating the patching lifecycle of multiple infrastructure areas. This is an engineering execution role - you are responsible for delivery outcomes within your domain, not just coordination across them.

Our practitioners work collaboratively within integrated, cross-functional teams. You will provide hands-on technical design guidance to your engineering team, drive sprint-level delivery, and coordinate with adjacent infrastructure and engineering domains. You will be expected to solve architecture and integration problems that your engineers bring to you, and to surface domain-level risk before it becomes a program-level issue. Domain openings are available across:
Database (Oracle, SQL, MongoDB, Redis, Postgres), Middleware, Cloud (AWS/Azure), Network, End User Compute, and Mainframe.

• 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

• Design, plan, and execute end-to-end patch delivery program for IBM z/OS mainframe and IBM i (AS/400) environments
• Manage the patch lifecycle end to end: identification, testing, scheduling, application, and post-implementation validation
• Understand patch windows across development, QA, and production environments
• Maintain patch compliance dashboards and KPIs

• 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, Service Now, SDSF) to reduce manual touchpoints
• Design automated compliance checks, health monitoring, and alert frameworks for patch-related activities
• Coordinate with Dev Ops teams to incorporate mainframe automation into CI/CD pipelines where applicable

• Serve as a primary technical point of contact for client…
