- Validate network device behavior, including forwarding performance, buffering characteristics, and deterministic operation.
- Evaluate and compare technologies from multiple vendors through objective testing and analysis.
- Build Python-based automation frameworks and analyze large data sets generated by test scenarios.
- Perform packet-level investigations and root-cause analysis of performance-related issues.
- Produce clear technical reports and management summaries, and contribute to network design discussions with data-driven recommendations.
- Solid understanding of networking fundamentals, including the OSI model, switching, routing, TCP/IP, and common protocols (TCP, UDP, BGP, multicast).
- Strong grasp of latency concepts (propagation delay, serialization delay, queuing delay, jitter) and physical layer technologies.
- Strong Python skills for test automation, data collection, statistical analysis, and visualization (e.g., Pandas, NumPy, Plotly).
- Experience creating and executing structured test plans, with the ability to perform precise measurements and interpret results.
- Proficiency in Linux environments and familiarity with Git and software development workflows.
