About the role

Key responsibilities & impact
  • Deploy, validate, and support Ethernet fabrics used for AI and HPC cluster environments
  • 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

Requirements

What you’ll need
  • 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
