Design, build, and operate the network fabric that interconnects our GPU fleet, including spine-leaf architectures, RDMA/RoCEv2 networks for distributed inference, and overlay networks for tenant isolation.
Own L2/L3 network design across bare-metal and cloud environments, including BGP peering, ECMP, VXLAN/EVPN, and high-bandwidth interconnects between data centers.
Develop and maintain network automation using Ansible, Terraform, and custom tooling to provision, configure, and validate switches, routers, DPUs, and SmartNICs at scale.

Requirements:

8+ years of experience building and operating large-scale networks, ideally in GPU cloud, HPC, or hyperscale environments.
Deep expertise in Linux networking internals: kernel networking stack, iptables/nftables, tc, eBPF, network namespaces, bonding/teaming, and SR-IOV.
Strong command of routing and switching protocols: BGP, OSPF, ECMP, VXLAN, EVPN, MPLS, and segment routing.
