•                         Evaluate and optimize mainframe capacity (MSU) and LPAR workloads, ensuring balance between performance and cost.

•                         Oversee datacenter operations, monitoring strategies, middleware (MQ, File Transfer like CFT), firewall/security clearance, and release management.

•                         Ensure full documentation of designs, optimizations, and lifecycle activities for audit and compliance.

2. Cross-Stakeholder Collaboration

•                         Work closely with stakeholders across locations and India, aligning infrastructure with business and IT objectives.

•                         Collaborate with application owners, operations teams, and project leaders to provide ongoing technical support.

•                         Act as the primary liaison with Vendors, IBM and other solution providers, driving technical synergies.

•                         Lead joint technical discussions with Vendors, ensuring solution alignment with transformation and exit strategies.

3. Technical Transformation & Insourcing

•                         Lead the transition of mainframe responsibilities from other locations to India, ensuring smooth handover and knowledge transfer.

•                         Build and mentor an India-based managed services team, progressively taking over steady-state operations.

•                         Develop a structured roadmap for insourcing and governance alignment, balancing compliance, cost, and performance.

•                         Provide regular technical assistance to project teams, ensuring infrastructure readiness and support.

4. KPI Ownership & Reporting

•                         Define, monitor, and report technical KPIs (capacity, performance, availability, incident management, and cost optimization).

•                         Deliver regular KPI dashboards and reports to senior management.

•                         Enforce KPI adherence across both internal teams and external vendors, driving corrective actions where required.

5. Decommissioning & Dismantling

•                         Lead the end-to-end decommissioning of mainframe components across software, middleware, and hardware.

•                         Manage license offboarding and termination (e.g., IDMS, CA/Broadcom), ensuring no residual dependencies remain.

•                         Oversee datacenter hardware dismantling and disposal, ensuring compliance with security and regulatory requirements.

•                         Collaborate with security and governance teams to revoke access, certificates, and data securely.

•                         Create detailed decommissioning playbooks, closure documentation, and audit-ready reports.

6. Housekeeping & Lifecycle Management

•                         Own and manage all housekeeping activities end-to-end (storage cleanup, archival, job scheduling, patching, log retention, etc.).

•                         Standardize housekeeping routines into clear runbooks, automating where possible.

•                         Ensure lifecycle management of mainframe systems, from capacity planning to decommissioning.

•                         Report housekeeping outcomes and ensure alignment with compliance and audit needs.

7. Knowledge Continuity & Documentation

•                         Take full ownership of knowledge transfer from existing responsible teams, leaving no knowledge gaps.

•                         Establish a structured knowledge base capturing infrastructure, decommissioning, and housekeeping processes.

•                         Regularly update documentation to reflect system changes, exit milestones, and best practices.

Skills & Competencies

•                         Deep expertise in mainframe optimization (MSU, LPAR), datacenter operations, and middleware integration.

•                         Hands-on experience in mainframe decommissioning, dismantling, and license termination.

•                         Strong understanding of housekeeping routines and lifecycle management in mainframe environments.

•                         Proven ability to lead cross-country transitions (Other locations to India) and multi-vendor ecosystems.

•                         Strong vendor and partner collaboration skills.

•                         Strategic mindset to balance stability, compliance, cost optimization, and modernization.

•                         Excellent communication, documentation, and executive reporting capabilities.

•                         Leadership in building, mentoring, and scaling technical teams in a managed services model.
