## Description

Sr Ethernet AI Network Engineer to provide senior network engineering services for Ethernet based AI data center fabrics supporting GPU compute clusters, storage connectivity, and management plane services. This role requires strong operational judgment, advanced troubleshooting capabilities, and the ability to resolve complex network issues within large scale production environments.
This is a 12 month remote contract opportunity within the United States.

Responsibilities:

 * Deploy, validate, and support Ethernet fabrics used for AI and HPC cluster environments.
 * Troubleshoot Layer 1 through Layer 4 issues involving optics, transceivers, cabling, link bring up, VLANs, MLAG, ECMP, BGP, underlay and overlay reachability, congestion, and packet loss.
 * Validate network readiness for distributed training workloads and large east west traffic patterns.
 * Diagnose performance issues related to buffer pressure, microbursts, PFC behavior, Quality of Service policy, MTU mismatches, routing instability, and oversubscription.
 * Partner 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 activities.
 * Capture packet level and counter based evidence to support root cause analysis.
 * Develop operational standards for cable mapping, port policy consistency, and fabric health validation.
