The ideal candidate must possess deep Mainframe testing and migration expertise and have prior experience leading testing efforts for Mainframe modernization, platform migration, or legacy transformation programs. A key responsibility of this role is establishing a risk-based testing strategy, ensuring testing effort is aligned to the scope and complexity of changes introduced by the migration rather than applying uniform testing across all components

  • Establish testing standards, quality gates, entry/exit criteria, and governance processes.
  • Develop a risk-based testing methodology aligned to migration waves and cutover milestones.

Test Planning & Design
  • Develop comprehensive testing plans covering:
    • System Testing
    • System Integration Testing (SIT)
    • End-to-End Business Process Testing
    • Regression Testing
    • Data Validation & Reconciliation Testing
    • Performance & Volume Testing

Mainframe & Migration Validation
  • Define testing coverage for:
    • COBOL applications
    • CICS transactions
    • JCL conversion and batch processing
    • VSAM, DB2, and IMS databases
    • File transfers and interfaces
    • Security configurations and access controls
    • Enterprise schedulers
    • Infrastructure and operational procedures
  • Validate functional equivalence and operational readiness of workloads migrated to z/OS.
  • Ensure proper reconciliation of converted data and migrated business processes.

Federated Test Leadership
  • Coordinate testing across:
    • Mainframe Teams
    • Application Teams
    • Infrastructure Teams
    • Security Teams
    • Database Teams
    • Business SMEs
  • Establish testing standards and reusable assets across workstreams.
  • Lead defect triage, prioritization, and remediation activities.
  • Drive issue resolution and dependency management across teams.

Cutover Readiness & Deployment Validation
  • Define cutover rehearsal and mock migration testing strategies.
  • Validate production deployment procedures and rollback capabilities.
  • Ensure all critical business processes are successfully executed during rehearsal events.
  • Provide Go/No-Go recommendations for migration releases.

  • Demonstrated experience leading testing for Mainframe modernization, platform upgrades, rehosting, or z/VSE-to-z/OS migration initiatives.

Risk-Based Testing Expertise
  • Proven experience implementing risk-based testing methodologies within complex transformation programs.
  • Strong ability to conduct migration impact assessments and translate findings into targeted testing strategies.
  • Experience identifying and prioritizing testing scope based on technical, business, operational, and compliance risks.
  • Ability to balance test coverage, quality, and program timelines through intelligent risk management.

Leadership & Communication
  • Experience leading large, cross-functional testing organizations.
