Network Engineer (MSIC)
COLSA, Huntsville, AL, United States
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).
At COLSA, people are our most valuable resource and centered at our core value. We invite you to unite your talents with opportunity and be a part of our “Family of Professionals”! Learn about our employee‑centric culture and benefits here.
