Network Implementation & Validation: Configure, deploy, test, and validate enterprise network infrastructure and security services across IPv4/IPv6, LAN/WAN, campus, branch, data center, and cloud environments, including routing, switching, VLANs, VRFs, BGP, OSPF, SDN, SD-WAN, DNS, DHCP, NAT, load balancing, firewalls and ACL policy enforcement, network segmentation, SASE, network orchestration, policy-as-code, and Zero Trust architecture. Experience should include high-bandwidth, low-latency network design for large-scale east-west traffic patterns, fabric architectures such as leaf-spine, and technologies such as high-speed Ethernet and/or InfiniBand, RDMA/RoCE, network segmentation, load balancing, resiliency, and performance testing to support AI/ML training and inference workloads.
