Founded in 2019, Swift supports Civilian, Defense, and Intelligence Community customers across the country and around the globe.
About the role
We’re looking for a highly experienced Network Engineer to join our growing team. The ideal candidate is a well-rounded network professional who brings deep technical expertise across the full spectrum of enterprise networking — from core routing and switching to modern cloud-integrated, AI-ready infrastructure. This role demands someone who can architect, operate, and evolve complex networks in support of mission-critical government and intelligence community environments.
We have opportunities in Network Engineering in Herndon, VA; McLean; VA; and Chantilly; VA.
Responsibilities:
•
Network Architecture & Design: Design, implement, and manage enterprise and service-provider scale networks spanning LAN, WAN, data center, and cloud environments, ensuring reliability, scalability, and security at every layer.
•
Routing & Switching: Configure and optimize dynamic routing protocols (BGP, OSPF, EIGRP, IS-IS) and advanced switching technologies (STP, LACP, VTP, 802.1Q) across complex multi-site topologies.
•
Cloud & AI Infrastructure: Architect and operate Cisco Cloud & AI Infrastructure (CAI) solutions, including data center fabric, AI/ML networking, and high-performance compute connectivity; support integration of AI workload infrastructure into enterprise and hybrid cloud environments.
•
MPLS & Transport Services: Design and deliver MPLS/BGP transport services; manage integrations between service provider and customer environments.
•
Network Security: Enforce security controls including next-generation firewalls, VPNs (IPsec/SSL), ACLs, network segmentation, and Zero Trust architecture; collaborate closely with Cybersecurity teams on policy and compliance.
•
Cloud & Hybrid Networking: Architect and manage SD-WAN, SDN, and NFV solutions; design and support hybrid cloud networking across AWS, Azure, and/or GCP, including connectivity, routing, and security policy enforcement.
•
Automation & Infrastructure-as-Code: Automate network provisioning, configuration management, and validation using Ansible, Python, Terraform, and similar tools; integrate with CI/CD pipelines and infrastructure-as-code workflows.
•
Network Access Control: Deploy and manage NAC technologies (e.g., Cisco ISE) to enforce endpoint compliance and control access to sensitive network segments.
•
Network Management & Assurance: Administer enterprise network management platforms; leverage AI/ML-driven analytics, telemetry, and assurance tooling to proactively monitor performance, identify anomalies, and drive rapid issue resolution.
•
Operations & Incident Response: Serve as the Tier 3/4 escalation point for complex network incidents; conduct root cause analysis, capacity planning, lifecycle management, and performance tuning.
•
Documentation & Stakeholder Communication: Produce and maintain network designs, architecture diagrams, implementation plans, and change management documentation; deliver technical briefings to both technical and non-technical audiences.
•
Mentorship & Standards Development: Mentor junior engineers and contribute to organizational standards, engineering playbooks, and best practices.
