About the role

Senior Network Engineer with 12 to 20 years of experience to architect, deploy, and operate high-performance backend networks for large-scale AMD Instinct GPU clusters, focusing on RoCEv2/Ethernet, leaf-spine data center architectures, and related observability and automation.

Responsibilities

  • Architect, deploy, operate, and continuously improve high-performance backend networks for large-scale AMD Instinct GPU clusters.
  • Design network fabrics capable of supporting AI and HPC environments from racks to clusters containing 10,000+ GPUs.
  • Own the backend network architecture from the GPU server and NIC through the leaf-spine fabric.
  • Design and optimize high-speed Ethernet fabrics using RoCEv2 and 100/200/400 GbE.
  • Develop scalable network topologies (leaf-spine, Clos, fat-tree, rail-optimized, multi-plane, non-blocking).
  • Perform topology modeling, oversubscription analysis, traffic-flow analysis, bandwidth and port-capacity planning, and growth forecasting.
  • Configure, tune, validate, and troubleshoot RoCEv2 environments (PFC, ECN, DCQCN, QoS, ECMP, switch buffering, DSCP mappings).
  • Design and operate routing/switching (BGP, ECMP, VLAN, VRF, EVPN, VXLAN).
  • Optimize end-to-end communication across GPUs, NICs, switches, CPUs, PCIe devices, storage, and Linux networking.
  • Lead production incident response, root-cause analysis, corrective actions, and preventive engineering improvements for GPU cluster networks.
  • Plan and execute network expansions, scale-outs, fabric migrations, and capacity upgrades.

Qualifications

  • Bachelor’s or Master’s degree in Computer Engineering or related field, or equivalent practical experience.
  • CCIE Data Center or equivalent certification
