Primary responsibilities include designing and executing tests, developing automation, and collaborating with cross-functional teams to qualify switch platforms.

• Define test strategies and develop corresponding test plans and cases for L1–L4 switch features.
• Execute functional, integration, regression, and performance tests; document results and coverage.
• Develop and maintain test automation using Python (e.g., Pytest, Robot Framework).
• Integrate automated tests into CI/CD pipelines and monitor continuous quality metrics.
• Create test scripts for firmware validation on simulation platforms and support firmware-level testing.
• Use traffic-generation tools for packet verification and performance validation.
• Report and track defects with thorough documentation, logs, and traces.
• Participate in peer code reviews, test plan reviews, and cross-team validation activities.

Requirements

Must-have skills are listed first; nice-to-have items follow.
