• Define federated test strategy, standards, and governance.
• Design and deliver the testing platform, including test frameworks, test data services, and observability tools.
• Provide SDKs and templates for consistent test authoring.
• Partner with teams to bootstrap test coverage and establish shift-left practices.
• Deliver synthetic data generation, environment orchestration, and dependency virtualization.
• Centralize test results and provide traceability for stakeholders.
