The role emphasizes hands‑on configuration, monitoring, troubleshooting, and documentation to ensure network performance, resilience, and compliance in a regulated federal IT environment.

Key Responsibilities

• Configure and manage routers, switches, and virtual network components, including VLANs, VPNs, and subnetting, to support secure connectivity across on‑premises and cloud environments.
• Implement and support routing protocols such as OSPF and BGP, applying traffic optimization techniques to improve performance, resilience, and availability for critical applications.
• Assist with the deployment and operation of software‑defined networking (SDN) solutions and network automation using scripting tools such as Python or Ansible to streamline provisioning and configuration management.
• Implement foundational network security controls including firewalls, access control lists, and segmentation, ensuring configurations align to enterprise and government security baselines.
• Monitor network performance using standard tools, perform log analysis and packet capture, and troubleshoot incidents to restore services and reduce recurrence of issues.
• Support cloud networking constructs such as VPCs, load balancers, and hybrid connectivity, working with senior engineers and cloud teams to maintain consistent security and performance.
• Develop and maintain documentation of network architectures, configurations, standards, and operating procedures to support continuity, audits, and compliance activities.
• Participate in capacity planning and disaster recovery activities, providing data and observations that inform improvements to network reliability and scalability.

Required Qualifications

• Bachelor’s degree (or equivalent experience) in IT, Cybersecurity, Computer Science, Information Systems, Data Science, Software Engineering, or a related field.
• Approximately 1–3 years of experience supporting enterprise or cloud‑based network environments, including hands‑on work with routing, switching, and network security.
• Foundational knowledge of routing protocols, IP addressing, subnetting, and common network services, with exposure to SDN and network automation concepts.
• Experience implementing or supporting network security controls such as firewalls, ACLs, and segmentation in regulated or compliance‑driven environments.
• Ability to obtain and maintain an active Secret clearance; must be eligible under applicable DoD 8140 requirements as defined for the role.
• U.S. citizenship required.
• Strong written and verbal communication skills, with the ability to clearly document configurations and procedures and collaborate with cross‑functional IT teams.

Preferred Qualifications

• Experience working within DoD or federal network compliance frameworks and associated security baselines.
• Industry certifications such as CompTIA Network+, Cisco CCNA, or equivalent vendor‑neutral or vendor‑specific network certifications.
• Exposure to infrastructure‑as‑code practices and automated network provisioning tools integrated into modern DevOps or cloud environments.
• Familiarity with major cloud service providers and their native networking features (e.g., VPCs, peering, VPN gateways, load balancers).
