Responsibilities
- Design and execute system- and solution-level validation plans and test cases from product requirements, architectures, and specifications.
- Validate functional, performance, resiliency, interoperability, and end-to-end scenarios across rack-scale networking and compute deployments.
- Test RoCE and lossless-fabric behavior under congestion, including PFC, ECN, link-level retransmission, and retransmits.
- Track link health across test runs and releases using error counters, link flaps, FEC, and CRC trends.
- Build and improve Python, SpyTest, and AI-agent automation to increase execution efficiency, CI/CD speed, and test coverage.
- Analyze logs, telemetry, packet captures, and system behavior to identify root causes, resolve complex issues, and close field escapes.
Requirements
- Experience with system testing and end-to-end validation of AI, data center, and enterprise networking solutions at multidimensional scale.
- Strong knowledge of VXLAN-EVPN, MLAG, EVPN-MH, ECMP, VRF, BGP, OSPF, IS-IS, SRv6, BFD, VLAN, LACP, LLDP, STP, multicast, DHCP, DNS, NTP, LDAP, RADIUS, TACACS+, and 802.1X.
- Experience with AI-fabric performance, including RoCE, QoS, DCB, PFC, ECN, lossless Ethernet, link-level retransmission, latency, resiliency, and GPU-cluster collective-communication traffic.
- Strong Python and test-automation skills, including automation frameworks, CI/CD pipelines, telemetry, northbound interfaces, packet analysis, and traffic-generator testing such as IXIA.
- Bachelor’s or master’s degree in Engineering in CSE, ECE, EEE, IT, Computer Networks, Cloud Computing, or an equivalent field.
- Hands-on SpyTest and network-test automation experience is desirable.
- Familiarity with server and storage environments, SDD/TDD, SQL, pandas, and trend and escape analysis is desirable.
- Experience with AI agents and AI-assisted workflows using tools such as Claude, Devin, and GitHub Copilot is desirable.
- Exposure to UALink and Ultra Ethernet is desirable.
