Network Engineer with Security Clearance

Summary
The Network Engineer serves as a senior technical leader responsible for the design, implementation, and optimization of secure enterprise network infrastructure across large-scale Department of Defense (DoD) environments. This role bridges architectural design and hands-on engineering by translating high-level network strategies into deployable solutions while actively building, securing, and troubleshooting complex networks.
The position focuses heavily on Zero Trust architecture, including endpoint compliance (Comply to Connect / C2C), network access control (NAC), and application micro-segmentation using tools such as Cisco Secure Workload. The engineer will play a key role in enforcing secure, policy-driven access, improving application visibility, and protecting data flows across globally distributed and hybrid cloud environments. Key Responsibilities • Translate architectural designs into engineering plans, configurations, and deployment strategies • Design, deploy, configure, and maintain enterprise network infrastructure, including routers, switches, firewalls, and load balancers • Implement and maintain Zero Trust security frameworks, including: ○ Endpoint compliance and device authentication (C2C) ○ Network access control (NAC) ○ Micro-segmentation and workload protection (Cisco Secure Workload) • Engineer and support Software-Defined Networking (SDN) solutions, including Cisco ACI • Develop and enforce secure application data flows across data centers and multi-cloud environments • Perform advanced troubleshooting across network layers, including routing protocols such as BGP and OSPF • Ensure all configurations meet DoD STIG and RMF compliance standards • Collaborate with cybersecurity, systems engineering, and cloud teams to ensure secure integration across environments • Develop and maintain comprehensive documentation, including architecture diagrams, data flows, and SOPs • Evaluate and test new technologies, firmware, and security updates prior to deployment Required Qualifications • Active TS/SCI clearance • DoD 8570 IAT II certification • CCNA or CCNP certification (CCNP preferred for senior candidates) • Minimum years of experience based on education: ○ 12 years (HS), 10 (Associate), 8 (Bachelor’s), 6 (Master’s), 3 (PhD) • Strong experience with: ○ Enterprise Cisco networking (routing, switching, firewalls) ○ Network security and Zero Trust concepts ○ Troubleshooting complex network environments • Experience working in DoD or government network environments Desired Qualifications • DoD 8140 compliance (Work Role Code 441 – Network Operations Specialist) • CCNP or CCIE certification • Experience with Cisco ACI (SDN) or SD-WAN technologies • Experience with Cisco Secure Workload or similar micro-segmentation tools • Hands-on experience with Comply to Connect (C2C) or NAC solutions • Background in network automation (Python, Ansible, REST APIs)
