About The Position

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.

Requirements

High-performance data center network architecture, deployment, and optimization experience.
Experience bridging traditional enterprise networking and specialized High-Performance Computing (HPC) environments.
Management of physical and logical pathways supporting low-latency fabrics, large-scale virtualization clusters, and high-density AI/ML and compute workloads.
Experience maintaining highly reliable, lossless network performance across multi-vendor leaf-spine topologies and high-throughput data pipelines.
Experience with Cisco ACI environments, including Multi-Pod and Multi-Site configurations.
Experience with high-density routing and switching platforms.
Experience engineering and tuning InfiniBand and RoCEv2 fabrics.
Experience configuring, auditing, and troubleshooting BGP, OSPF, and EVPN overlay deployments.
Experience with multi-vendor infrastructure, including Cisco Nexus, Arista, and NVIDIA/Mellanox.
Experience optimizing Quality of Service (QoS), Priority Flow Control (PFC), and Explicit Congestion Notification (ECN).
Experience integrating network fabrics with virtualization platforms, including VMware NSX, KVM, and Nutanix.
Experience with high-speed storage networks such as NVMe-oF.
Experience analyzing network telemetry for bandwidth demand forecasting.
Experience with network automation tools, including Python and Ansible.
Knowledge of DoD security baselines, DISA STIGs, and operational security standards for classified processing environments.

Responsibilities

Design, deploy, and maintain Cisco ACI environments, including Multi-Pod and Multi-Site configurations, across high-density routing and switching platforms.
Engineer and tune InfiniBand and RoCEv2 fabrics to support ultra-low-latency requirements for data-intensive mission workloads.
Configure, audit, and troubleshoot complex BGP, OSPF, and EVPN overlay deployments across multi-vendor infrastructure, including Cisco Nexus, Arista, and NVIDIA/Mellanox.
Optimize Quality of Service (QoS), Priority Flow Control (PFC), and Explicit Congestion Notification (ECN) to support lossless traffic flow and consistent network performance.
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.
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.
Ensure network architectures adhere to DoD security baselines, DISA STIGs, and operational security standards required for classified processing environments.
