As a Senior Network Engineer supporting the Next Generation Environment (NGE) on the Integrated Research and Development for Enterprise Solutions (IRES) contract, you will serve as a senior technical contributor responsible for engineering, configuring, implementing, and securing the high-speed data center fabrics and software‑defined network enclaves underpinning the Missile Defense Agency’s (MDA) unified digital environment.

In this role, you will turn high-level architectural designs into resilient, automated network solutions by configuring Cisco Nexus Spine-Leaf EVPN‑VxLAN fabrics, VMware NSX software‑defined networks, Versa SD‑WAN edge transport, F5 BIG‑IP application delivery controllers, and Infoblox enterprise DDI services. You will collaborate across engineering, systems architecture, systems security, multi‑contractor consortium performers, and Government stakeholder teams to deliver cohesive hybrid cloud and on‑premises network transport.

You will play a key role in standardizing infrastructure automation, resolving complex tier‑3/4 routing issues, enforcing Zero Trust boundaries, and ensuring continuous network compliance with DoD, DISA, and MDA security requirements.

• Configure, deploy, and administer Cisco Nexus (NX‑OS) switches operating in high‑performance Spine‑Leaf topologies.
• Build, maintain, and optimize EVPN‑VxLAN virtual overlay networks, Multi‑Site fabrics, vPC domains, and complex underlay routing baselines.

• Deploy, configure, and manage VMware NSX components including NSX Edge nodes, Tier-0 and Tier-1 logical gateways, and distributed firewalls.
• Implement policy‑driven micro‑segmentation rules within virtualized compute environments (vSphere/VCF) to isolate mission workloads and support multi‑tenant enclaves.

• Deploy, configure, and maintain F5 BIG‑IP physical and virtual appliances, specifically Local Traffic Managers (LTM) and Global Traffic Managers (GTM).
• Author and troubleshoot custom F5 iRules, and configure virtual servers, load‑balancing pools, health monitors, and secure SSL/TLS decryption profiles.

• Provision, deploy, and maintain Versa SD‑WAN edge appliances (including Director, Analytics, and VOS) to establish secure transport across disparate WAN paths.
• Configure secure tunneling, dynamic traffic steering rules, QoS queue policies, and security boundaries for remote sites and tactical test networks.

• Administer enterprise‑wide IP Address Management (IPAM), authoritative internal DNS zones, and DHCP scopes utilizing Infoblox Grid Manager.
• Support the automation of DNS records and IP allocation using Infoblox APIs integrated with Infrastructure‑as‑Code pipelines.

• Implement identity‑aware access controls, 802.1X network access control (NAC), and FIPS‑compliant cryptography tunnels (IPsec/MACsec).
• Harden all network assets in accordance with DISA STIGs, Risk Management Framework (RMF) guidelines, and MDA cybersecurity requirements to support continuous ATO (cATO).

• Coordinate and collaborate directly with external contractor performers and systems administrators across the program consortium during joint integration events, lab setups, and production cutovers.
