Role Description
- High-Level Strategy & Governance
End-to-End Environment Orchestration: Manage complex test regions (CICS regions, DB2 subsystems) and coordinate with Systems Programmers to ensure environment stability.
Risk-Based Testing (RBT): Lead impact analysis for massive code drops, identifying critical paths in the Job Entry Subsystem (JES) to prioritize testing where failures would be most catastrophic.
Defect Governance: Lead defect triage meetings between development, business analysts, and stakeholders. Provide technical evidence (e.g., dump analysis, trace logs) to expedite fixes.
- Expert Technical Validation
The candidate must demonstrate "Power User" status in the z/OS environment.
Complex Batch Validation: Expert in JCL override procedures, cataloging/uncataloging datasets, and using GDGs (Generation Data Groups) for regression testing.
DB2 & Data Integrity: Beyond simple SELECT statements; they must understand DB2 referential integrity, perform data loads/unloads, and validate complex stored procedures.
Utilities Mastery: Advanced use of File-Aid, IBM File Manager, or BMC Mainview to manipulate VSAM files and verify data at the byte level (Hexadecimal/EBCDIC).
- Modernization & Automation (The "Bridge" Skills)
As Mainframe teams adopt DevOps, the Senior Tester must lead the transition.
Automated Regression: Experience using tools like IBM Rational Test Workbench or writing REXX/CLIST scripts to automate repetitive validation tasks.
API & Integration Testing: Validating the integration between the Mainframe core and distributed front-ends (Java/Mobile) via MQ Series or RESTful APIs.
Shift-Left Strategy: Implementing unit testing and code quality gates earlier in the cycle using tools like Zowe or SonarQube for Mainframe.
