JOB DESCRIPTION

This Network Engineer is responsible for the architecture, deployment, and optimization of high-performance data center networks. This role bridges the gap between traditional enterprise networking and innovative High-Performance Computing (HPC) environments. You will be the primary authority on low-latency fabrics, managing the physical and logical pathways that power large-scale virtualization clusters and AI/ML workloads.

The ideal candidate treats the network as a high-speed highway, ensuring zero-packet-loss delivery for data-intensive applications.

RESPONSIBILITIES

* Design and maintain Cisco ACI (Application Centric Infrastructure) environments, including Multi-Pod and Multi-Site connectivity.

* Deploy and tune InfiniBand (Subnet Managers, Leaf/Spine topology) and RoCEv2 (RDMA over Converged Ethernet) to support low-latency requirements.

* Configure and troubleshoot complex BGP, OSPF, and EVPN-VXLAN deployments across a multi-vendor landscape.

* Optimize Quality of Service (QoS) and Priority Flow Control (PFC) to prevent congestion in RDMA-heavy environments.

* Collaborate with systems teams to integrate networking with VMware NSX, KVM, or Hyper-V, ensuring seamless East-West traffic flow.

* Analyze telemetry data to forecast bandwidth needs for massive data ingest and high-speed storage arrays (NVMe-oF).
