Job Description Job Description 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. Key Responsibilities 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. 2. 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. 3. 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. 4. 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. 5. 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. 6. 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. Requirements 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.

Job Description Job Description We are seeking a Senior Network Security Engineer for an operations-first role supporting enterprise network security infrastructure across on-premises, remote-access, hybrid-cloud, and cloud-connected environments. This is not primarily an architecture/design role. The priority is a hands-on engineer who can administer, configure, maintain, troubleshoot, patch, upgrade, back up, validate, document, and operate production security platforms with minimal ramp-up. Firewall operations: hands-on Cisco and Palo Alto firewall administration, rule changes, NAT, troubleshooting, policy cleanup, upgrades, backups, logging, and production support. VPN / remote access: support for remote-access VPN, site-to-site VPN, user connectivity issues, certificates, authentication flows, and after-hours troubleshooting. RSA / MFA administration: RSA SecurID or equivalent MFA operations, token support, server administration, user troubleshooting, VPN integration, certificates, patching, backups, logs, and monitoring. Day-to-day operations: ticket resolution, monitoring alerts, health checks, change requests, incident support, maintenance windows, operational reporting, and customer support. Configuration and administration: installing, configuring, maintaining, patching, upgrading, backing up, validating, and troubleshooting assigned security platforms. Production troubleshooting: strong TCP/IP, DNS, routing, firewall logs, packet captures, VPN authentication, certificate, and connectivity troubleshooting. Documentation and process discipline: SOPs, runbooks, diagrams, change records, rollback plans, evidence collection, knowledge transfer, and formal change management.

Respond to incidents, vulnerability notices, urgent requests, vendor advisories, PSIRT notices, system alerts, and emergency troubleshooting while minimizing service disruption. Use firewall logs, VPN logs, packet captures, SIEM data, monitoring tools, DNS/routing checks, and standard diagnostics to resolve complex connectivity, authentication, TLS/certificate, and application-flow issues. Create and maintain topology diagrams, equipment inventories, configurations, SOPs, runbooks, implementation plans, rollback plans, build/upgrade procedures, troubleshooting notes, and knowledge articles. Follow approved change, release, incident, problem, and configuration-management processes; prepare change records, peer-review materials, validation evidence, root-cause analysis, metrics, and audit artifacts. Support vulnerability remediation, POA&M tracking, continuous monitoring, compliance reviews, audit evidence collection, and coordination with ISSO, system owner, and security governance teams. Requirements 7+ years of experience in network security engineering, network infrastructure, cybersecurity infrastructure, or a closely related role. 5+ years of hands-on experience administering, maintaining, and troubleshooting enterprise firewall platforms in production environments. Hands-on experience with Cisco security technologies such as Cisco ASA, Firepower, FTD, FMC, AnyConnect/Secure Client, or equivalent Cisco firewall/VPN platforms. Hands-on experience with Palo Alto Networks technologies such as NGFW, Panorama, GlobalProtect, security profiles, App-ID/User-ID, logging, and policy optimization. Experience administering or supporting RSA SecurID Authentication Manager or comparable enterprise MFA/two-factor authentication platforms, including token support, server operations, patching/upgrades, backups, certificates, monitoring, and directory/VPN integration. Strong knowledge of firewall policy, NAT, VPNs, routing, DNS, DHCP, BGP, TLS/certificates, packet captures, log analysis, segmentation, high availability, and common network diagnostic tools. Experience with enterprise monitoring, logging, SIEM, alerting, vulnerability management, incident response, formal change management, and regulated-environment documentation. Ability to create clear technical documentation, support customers and stakeholders, prioritize operational work, communicate clearly, and coordinate across technical teams. Ability to obtain and maintain a Public Trust background investigation. Desired Certifications Relevant certifications are helpful but should not replace demonstrated hands-on experience.
