Key Responsibilities

1. Platform Ownership & Optimization

- Own the design, optimization, and lifecycle management of the mainframe infrastructure.
- 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.
- Solid 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.
