## About the Role

Ethernet, Artificial Intelligence (AI), Identify Issues, Network Architecture/Engineering, Network Operations Center, Artificial Intelligence (AI), GPU (Graphics Processing Unit), Ethernet, BGP, VLAN (Virtual Local Area Network), * 7+ years in large-scale data center networking, including high-bandwidth Ethernet fabrics.

 * Strong experience with spine-leaf design, routing, switching, and production troubleshooting.
 * Hands-on skill with BGP, EVPN/VXLAN, MLAG, ECMP, QoS, PFC, RoCE considerations, and telemetry interpretation.
 * Experience validating optics, breakout configurations, cable plant integrity, and port-level consistency.
 * Proven ability to troubleshoot distributed application impact caused by network behavior.
 * Comfort using switch CLI, automation tooling, and packet/counter analysis workflows.
 * Strong documentation habits for topology, incident timelines, and remediation plans.

PREFERRED EXPERIENCE

 * Direct experience with AI fabrics carrying large-scale GPU collective traffic.
 * Familiarity with SONiC, Cumulus Linux, or vendor NOS platforms used in AI data centers.
 * Experience with streaming telemetry, Prometheus/Grafana, and network SRE operating models

## Description

* Troubleshoot L1 through L4 issues involving optics, transceivers, cabling, link bring-up, VLANs, MLAG, ECMP, BGP, underlay/overlay reachability, congestion, and packet loss.
 * Validate network readiness for distributed training and large east-west traffic patterns.
 * Diagnose performance issues related to buffer pressure, microbursts, PFC behavior, QoS policy, MTU mismatch, routing instability, and oversubscription.
 * Work closely with Linux, storage, and cluster deployment teams to isolate host-versus-network fault domains.
 * Review and execute change plans for switch provisioning, firmware upgrades, topology expansion, and maintenance events.
 * Capture packet-level and counter-based evidence to drive root cause analysis.
 * Build operational standards for cable mapping, port policy consistency, and fabric health validation.
