The Opportunity:
A well-designed network is critical to move data and enable the Department of Defense (DoD) to achieve their missions, but how can an organization make sure their network will fit their evolving needs? Crafting the right network, with the right equipment and software, requires a combination of technical skill and careful planning. That’s why we need a seasoned Network Engineer like you who knows how to develop the exact network the DoD needs.
As a Network Engineer on our team, you’ll use your experience in network design and architecture, system interoperability, OSI model, network transport layers, multi-protocol label switching, gateway protocol, and virtual routing and forwarding to support the nation’s defense and respond to evolving adversaries. You’ll develop enterprise-wide infrastructure design, troubleshoot and resolve complex network issues, analyze current working infrastructures, and increase security, reliability, and availability for critical network systems. You’ll apply your expertise in routing and switching, network design and architecture, system interoperability, IP engineering, network transport layers, multi-protocol label switching, gateway protocol, and virtual routing and forwarding as you guide our team of problem-solvers to help the DoD evolve and deploy new capabilities and technologies. Your knowledge of enterprise-level network protocols, equipment, emerging technology, and configurations will come in handy as you optimize client operations and modernization. Using your experience in software and hardware firewalls, Cisco hardware, Palo Alto firewalls, Juniper hardware, and optical infrastructure networking, you’ll serve as a trusted advisor to clients on critical projects. Using your technical curiosity and knowledge of industry standards, you’ll make an impact on national security-related missions.
