Network Test​/Validation Engineer

The Network Test / Validation Engineer will perform solution-level and high-scale network testing and validation across VxLAN/EVPN, MPLS overlays, QoS, and RoCE/RoCEv2 environments. The role requires strong hands-on expertise with Ixia (IxNetwork) or Spirent to design and execute large-scale performance, convergence, stress, and traffic validation tests. The engineer will validate network behavior and performance at scale while leveraging Python and REST APIs for test automation and reporting.

• Perform solution-level and scale testing for VxLAN/EVPN, MPLS overlays, QoS, and RoCE/RoCEv
  2.
• Design and execute high-scale traffic and protocol emulation using Ixia (IxNetwork) or Spirent.
• Validate throughput, latency, jitter, packet loss, microbursts, and convergence at scale.
• Test QoS behaviors, including classification, queuing, shaping, policing, and congestion handling.
• Validate RoCE lossless fabric behavior, including PFC, ECN, congestion behavior, and latency sensitivity.
• Automate test execution and reporting using Python and REST APIs.
• Develop clear test plans and document test results.
• Identify, troubleshoot, and document defects discovered during network testing and validation.

• Experience in network testing, network validation, or performance engineering.
• Strong hands-on experience with VxLAN/EVPN and MPLS.
• Solid understanding of QoS design and validation.
• Experience testing RoCE/RoCEv2 environments.
• Very strong hands-on experience with Ixia (IxNetwork) or Spirent, preferably in high-scale testing environments.
• Experience with Python-based test automation.
• Strong understanding of BGP, including EVPN.
• Strong understanding of OSPF and/or IS-IS.
• Strong understanding of ECMP.
• Experience designing and executing large-scale performance, convergence, and stress tests.
