Senior Ethernet AI Network

• 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.
