• Model workloads, profile end-to-end performance, analyze bottlenecks, and produce benchmark reports.

• Validate Cisco network-switch, multi-plane, ToR, compute, storage, and software integrations.

• Drive defect triage, evidence collection, release qualification, RA certification, and acceptance-report packaging.

• Bachelors + 7 years of related experience, or Masters + 4 years of related experience, or PHD +1 year of related experience, or equivalent related work experience.

• Experience building and executing end-to-end validation for GPU or distributed AI systems.

• Experience with test strategy, automation, Python, Linux, performance analysis, and defect-triage skills.

• Prior experience translating system requirements into measurable tests, acceptance criteria, and release gates.

• Experience with technical writing and cross-functional communication.
