Description

COLSA Corporation is seeking a Network Engineer to support the Missile and Space Intelligence Center (MSIC) in Huntsville, AL. This position supports high-performance data center network architecture, deployment, and optimization, bridging traditional enterprise networking and specialized High-Performance Computing (HPC) environments. The role manages the physical and logical pathways that support low-latency fabrics, large-scale virtualization clusters, and high-density AI/ML and compute workloads.

The Network Engineer is responsible for maintaining highly reliable, lossless network performance across multi-vendor leaf-spine topologies and high-throughput data pipelines.

  • Fabric Architecture & SDN: Design, deploy, and maintain Cisco ACI environments, including Multi-Pod and Multi-Site configurations, across high-density routing and switching platforms.
  • Low-Latency & HPC Connectivity: Engineer and tune InfiniBand and RoCEv2 fabrics to support ultra-low-latency requirements for data-intensive mission workloads.
  • Protocol & Routing Management: Configure, audit, and troubleshoot complex BGP, OSPF, and EVPN overlay deployments across multi-vendor infrastructure, including Cisco Nexus, Arista, and NVIDIA/Mellanox.
  • Lossless Performance Tuning: Optimize Quality of Service (QoS), Priority Flow Control (PFC), and Explicit Congestion Notification (ECN) to support lossless traffic flow and consistent network performance.
  • Hypervisor & Storage Integration: Integrate network fabrics with virtualization platforms, including VMware NSX, KVM, and Nutanix, and high-speed storage networks such as NVMe-oF to support high-throughput East-West traffic.
  • Capacity Planning & Automation: Analyze network telemetry to forecast bandwidth demands for large-scale data ingestion and leverage network automation tools, including Python and Ansible, to enforce configuration consistency and state control.
  • Security & Compliance: Ensure network architectures adhere to DoD security baselines, DISA STIGs, and operational security standards required for classified processing environments.
