Position Overview

We are reinforcing the network team that underpins a multi-tenant, multi-region GPU cloud at 10,000+ GPU scale. You will design and operate tenant network isolation and high-performance GPU interconnect, ensuring low-latency, lossless fabrics for distributed AI training alongside secure multi-tenancy.

Key Responsibilities

• Design, operate, and troubleshoot multi-tenant SDN: tenant isolation, VPC / overlay networking, and east-west / north-south traffic.
• Build and tune high-performance GPU interconnect fabrics (InfiniBand / RoCE) for distributed training, including lossless config and congestion control (PFC / ECN).
• Plan and operate cross-region interconnect and routing.
• Lead network change management and fast fault localization to minimize tenant impact.
• Partner with Compute and Control Plane teams on network-provisioning automation.
• Define network architecture standards, security boundaries, and observability.

Job Requirement

• 6+ years in datacenter / cloud networking or SDN.
• Deep expertise in multi-tenant isolation, overlays (VXLAN / EVPN), and L2 / L3 design.
• Hands-on with high-performance fabrics: InfiniBand and / or RoCE, RDMA — strongly preferred for GPU / HPC clusters.
• Experience with SDN controllers and network automation.
• Strong troubleshooting / fault-localization under production load.
• Multi-region network design experience a plus.
