The Job

Create performance test plans and test matrices for full/incremental backup, backup copy, full recovery, and relevant repository/storage scenarios.

Execute controlled baseline-versus-candidate comparisons; record duration, effective throughput, data volume, CPU, memory, network, and storage I/O metrics.

Build and maintain Python/Pytest automation and supporting scripts for test setup, job orchestration, metric collection, result comparison, reporting, and cleanup.

Validate test environment readiness (source workload, transporter, repository, network, capacity) before interpreting performance results.

Investigate performance regressions using logs and metrics; reproduce issues, identify likely bottlenecks, and partner with developers to validate fixes.

Run concurrency, scalability, and endurance studies; document resource saturation, limits, and performance trends.

Integrate automated checks into CI/CD and publish concise reports with build information, configurations, pass/fail criteria, and supporting evidence.

Apply AI-assisted techniques where beneficial, review generated code and findings, and maintain reliability, confidentiality, and test reproducibility.

Coordinate with manual QA, automation QA, development, and infrastructure teams; maintain test data and ensure reliable post-test cleanup
