Design and execute high‑scale traffic and protocol emulation using Ixia (IxNetwork)
Validate throughput, latency, jitter, loss, microbursts, and convergence at scale
Test QoS behaviors (classification, queuing, shaping, policing, congestion handling)
Validate RoCE lossless fabrics (PFC, ECN, congestion behavior, latency sensitivity)
Automate test execution and reporting using Python/REST APIs
Produce clear test plans, results, and defect reports
Required Skills
6–8+ Years in network testing/validation or performance engineering
Strong hands‑on expertise with VxLAN/EVPN and MPLS
