About The Position

DESE is seeking a Network Engineer in Huntsville, AL. 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.

Requirements

Bachelor's Degree in network engineering, Computer Science, or a related technical field.
Enterprise/Data Center networking with a focus on spine-leaf architectures.
Must possess (or be able to obtain) a DoD Top Secret Clearance with SCI eligibility including successful completion of a Counterintelligence (CI) Polygraph and willingness to meet Special Access Program (SAP) eligibility requirements.
Must possess an active CompTIA Security+ CE, ISC2 SSCP, or equivalent baseline certification.
Proficiency with high-density switching platforms (e.g., Cisco Nexus, Arista, or NVIDIA).

Nice To Haves

Enterprise/Data Center networking with a focus on spine-leaf architectures.
Active DoD Top Secret Clearance with SCI and a Counterintelligence (CI) Polygraph with willingness to meet Special Access Program (SAP) eligibility requirements.
CCNA Routing & Switching or higher, Nivida Networking, etc.
Demonstrated experience with HPC Clusters.
Knowledge of NVMe over Fabrics (NVMe-oF) and Fiber Channel over Ethernet (FCoE).
Ability to manage network state using Ansible, Terraform, or Python (Netmiko/NAPALM).

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).
