Hi,
I would like to share an excellent opening Full time Mainframe Test Architect with migration expertise with do go through the details and kindly send me the updated resume.
Location : Remote
Type of Hire : Contract
Mode of interview : WebEx / Teams
We are seeking an experienced Test Architect to lead the end-to-end testing strategy, planning, governance, and execution for a large-scale z/VSE to z/OS migration program. This role will be responsible for defining the testing approach, ensuring comprehensive coverage across applications, infrastructure, data, security, and operational processes, while providing overall quality and release readiness governance.
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

- Code modifications
- JCL conversion impacts
- Data migration changes
- CICS transaction changes
- Interface dependencies
- Security changes

- Identify migration-specific risks and ensure mitigation plans are incorporated into testing activities.
Test Planning & Design
- Develop comprehensive testing plans covering:
- System Testing
- System Integration Testing (SIT)
- End-to-End Business Process Testing
- Regression Testing

- 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.
