Network Architect SME

We are seeking a Subject Matter Expert (SME) Network Architect to join our team supporting a large-scale federal modernization program. This role owns enterprise and solution-level network architecture, designing secure, resilient network environments that support mission-critical systems and shared services across both cloud and on-premises boundaries, and driving the standards, target-state direction, and modernization roadmap that keep the network ready to scale.

This is a hands-on architecture role. You’ll be expected to produce real technical designs and see them through implementation, not just set direction from a distance.

This is a hybrid role based out of Washington, DC. Candidates must be U.S. citizens., 1. Network Architecture & Design

• Develop, review, and implement secure, resilient enterprise network architectures supporting mission systems and shared services.
• Produce and assess physical/logical diagrams, routing/segmentation, interfaces, connectivity, capacity, availability, and monitoring requirements.
• Design hybrid connectivity architecture spanning on-premises and cloud environments.

1. Standards & Target-State Direction * Define and maintain network architecture standards, reference patterns, and technical decisions. * Set target-state network direction and modernization roadmap, balancing scale, security, resilience, and performance. * Align network architecture with enterprise architecture governance and repository requirements.

2. Technical Reviews & Governance * Support technical reviews, architecture compliance reviews, phase gates, and implementation-readiness reviews. * Evaluate proposed deviations and provide recommendations grounded in risk and architectural impact.

3. Gap Analysis & Modernization * Analyze current-state network gaps, technical debt, lifecycle risk, single points of failure, and performance bottlenecks. * Provide recommendations for modernization, standardization, and optimization, including cost/performance tradeoffs.

4. Cross-Domain Coordination * Coordinate with cloud/platform, cybersecurity, identity, endpoint/mobility, applications, data, and ITSM teams, as well as external carriers and providers. * Resolve complex cross-domain design conflicts under fixed milestones.

5. Documentation & Operational Handoff * Maintain standards, reference patterns, technical decisions, configurations, risks, and dependencies in approved repositories. * Support implementation, testing, migration, and stabilization, and troubleshoot complex cross-domain problems, communicating root cause, options, and corrective actions.

• 12+ years of experience in network engineering, including significant architecture responsibility at enterprise scale.
• Strong fundamentals in TCP/IP, routing, switching, segmentation, DNS/DHCP/IPAM, load balancing, resiliency, performance, monitoring, and security.
• Demonstrated experience producing technical network designs and supporting implementation, testing, troubleshooting, and operational transition.
• Ability to work across cloud and on-premises boundaries and through formal security/architecture review processes.
• Strong documentation and communication skills, with experience presenting designs and tradeoffs to both engineers and leadership.
• U.S. Citizenship Required.

Nice to Have

• Direct federal, government, or large distributed enterprise network experience.
• Relevant Cisco, Juniper, cloud networking, SD-WAN, wireless, security, or architecture certifications.
• Experience with network automation, infrastructure as code, software-defined networking, zero trust, SASE/SSE, and observability.
• Experience with enterprise architecture repositories and technology standards/roadmaps.
