Rapid Strategy is a premier cybersecurity and IT consulting firm that partners with federal, defense, and commercial clients to deliver mission‑critical cybersecurity, network modernization, and cloud infrastructure solutions. Our work supports national security, operational resilience, and technology innovation across complex enterprise environments.

We are seeking an experienced Senior Network Administrator to support Security Operations Center (SOC) and Network Operations Center (NOC) activities for a federal government client in Washington, D.C. This role requires an active TS/SCI clearance and is 100% onsite.

Position Overview

The Senior Network Administrator will play a key role in managing both on‑premises and cloud network infrastructure within a 24/7 SOC/NOC environment. This position is responsible for designing, implementing, monitoring, and maintaining secure, high‑availability networks that span traditional data centers and cloud environments.

The ideal candidate will have expertise in enterprise networking, cloud networking architectures (VPCs, VPNs, and interconnects), and SD‑WAN deployments. This role requires a balance of hands‑on technical proficiency, operational discipline, and a commitment to supporting mission‑critical systems that protect national interests.

Key Responsibilities

• Administer, configure, and maintain LAN/WAN, SD‑WAN, VPN, and cloud‑based network infrastructures (AWS/Azure VPCs, routing, and peering).
• Ensure secure, reliable connectivity between on‑premises networks and cloud environments.
• Support SOC/NOC operations to maintain network availability, optimize performance, and support incident response activities.
• Manage and secure network devices (firewalls, routers, switches) following DISA STIGs and DoD compliance standards.
• Integrate and maintain network monitoring tools for proactive performance and security visibility (e.g., SolarWinds, Splunk, or Nagios).
• Implement and maintain network segmentation, Zero Trust principles, and access control policies.
• Collaborate with systems, security, and cloud teams to ensure compliance and consistent configuration management.
• Conduct vulnerability assessments and coordinate remediation using ACAS, Tenable/Nessus, or equivalent DoD‑approved tools.
• Maintain detailed network diagrams, documentation, and configuration baselines for audits and continuity.
• Evaluate and deploy emerging network and cloud technologies to enhance performance, scalability, and resilience.

Required Qualifications

• Active TS/SCI clearance (mandatory)
• Bachelor’s degree in Information Technology, Computer Science, or a related field (or equivalent experience)
• 5+ years of experience in network administration or engineering supporting federal or DoD environments
• Strong expertise in TCP/IP, routing, switching, VLANs, firewalls, and VPNs
• Hands‑on experience with Cisco, Juniper, or Palo Alto network equipment
• Experience configuring and maintaining SD‑WAN environments
• Proficiency in cloud networking (AWS/Azure VPCs, route tables, NAT gateways, VPN tunnels, hybrid connectivity)
• Familiarity with network security tools and frameworks (ACAS, Tenable, DISA STIGs, RMF)
• Strong troubleshooting, documentation, and communication skills

Preferred Qualifications

• DoD 8570 IAT Level II/III certification (e.g., Security+, CCNA Security, CASP+)
• Certifications such as CCNA, CCNP, or AWS/Azure Network Specialty
• Experience with network automation and scripting (Python, PowerShell, Ansible)
• Familiarity with Zero Trust Architecture (ZTA) and software‑defined networking (SDN) concepts
• Prior experience supporting SOC/NOC operations or Defense Information Systems Agency (DISA) networks
