Network Engineer SME

*This position will be a W2 Contract for 6 months potential to be extended or converted FTE - Eligibility to obtain Government clearance 

JOB SUMMARY:

The Principal Network Subject Matter Expert (SME) will serve as the technical authority for enterprise network architecture, modernization, resiliency, security, and performance on a high-priority federal infrastructure program. The SME will set technical direction, establish standards, and advise customer and program leadership across mission-critical environments.

The role combines strategic leadership with hands-on expertise to approve designs, develop target-state architectures and migration plans, resolve complex issues, and serve as the final technical escalation point. The SME will mentor engineering teams, coordinate cross-functional execution, and work primarily onsite at secure customer locations.

SUMMARY OF ESSENTIAL JOB FUNCTIONS:

• Serve as the onsite network technical authority and trusted advisor to customer and program leadership.
• Define network architecture principles, engineering standards, reference designs, and technology roadmaps for mission-critical environments.
• Assess network architecture, performance, capacity, resiliency, security, dependencies, and failure domains across enterprise, data-center, HPC, manufacturing, test, and remote-site environments.
• Develop and approve target-state architectures, bills of material, migration strategies, implementation plans, test plans, and operational-readiness criteria.
• Lead technical discovery, architecture reviews, and risk assessments; evaluate design alternatives and provide authoritative recommendations.
• Ensure network solutions meet requirements for routing, switching, segmentation, security, high availability, remote access, inter-site connectivity, observability, and disaster recovery.
• Serve as the final technical escalation point for complex incidents and performance issues, lead root-cause analysis, and drive corrective actions.
• Establish configuration, documentation, monitoring, and operational standards that improve consistency, supportability, and service performance.
• Communicate technical decisions, risks, dependencies, and trade-offs to customer stakeholders, program leadership, project managers, and engineering teams.
• Coordinate technical execution across network, security, systems, storage, facilities, DevOps, application, and program teams.
• Mentor engineers, provide technical oversight, and strengthen network engineering practices across the program.
• Support onsite assessments, maintenance windows, migrations, incident response, and post-implementation stabilization as required.

REQUIRED SKILLS AND EXPERIENCE:

The successful candidate will demonstrate deep network expertise, sound architectural judgment, and the ability to make technical decisions across customer, government, contractor, and engineering organizations.

• 10+ years of progressively responsible experience designing, modernizing, and supporting complex enterprise networks.
• Demonstrated experience serving as a network architect, technical authority, or senior escalation resource in mission-critical environments.
• Expertise with Cisco enterprise routing, switching, firewall, VPN, and data-center technologies.
• Advanced knowledge of BGP, OSPF, VLANs, VRFs, QoS, multicast, segmentation, high availability, and resilient network design.
• Experience developing and approving network architectures, standards, bills of material, migration strategies, implementation plans, test plans, and operational documentation.
• Strong knowledge of network security, including firewall policy, micro-segmentation, secure remote access, network access control, and Zero Trust principles.
• Expert-level troubleshooting and root-cause analysis across routing, performance, availability, DNS, DHCP, NTP, IP address management, authentication, and application connectivity.
• Experience with monitoring and observability technologies, including telemetry, SNMP, syslog, NetFlow/IPFIX, packet capture, alerting, and performance baselining.
• Proven ability to assess technical risk, evaluate design trade-offs, and communicate authoritative recommendations to technical and nontechnical stakeholders.
• Ability to lead cross-functional technical execution, mentor senior engineers, and work independently onsite in secure, regulated, federal, defense, manufacturing, or comparable environments.
• Initial 6‑month contract with strong potential for extension and possible conversion to a long-term full-time role.
• No active clearance required at start; however, candidates must be eligible to obtain and maintain a security clearance.
• Hybrid environment with on-site requirements still being finalized.
• Work may be performed at multiple Baltimore-area customer locations, and candidates should be flexible regarding worksite assignment and on-site frequency.

PREFERRED SKILLS AND EXPERIENCE:

• Knowledge of EVPN/VXLAN, software-defined networking, data-center fabrics, and high-performance or low-latency networks.
• Experience architecting network integration for VMware, Kubernetes, OpenShift, Tanzu, AWS, and hybrid-cloud platforms.
• Network automation experience using Python, Ansible, APIs, infrastructure as code, or CI/CD practices.
• Experience supporting operational technology, manufacturing, specialized test equipment, legacy platforms, air-gapped environments, or systems with limited maintenance windows.
• Knowledge of NIST 800-171, NIST 800-53, CMMC, vulnerability management, SIEM/EDR integration, and secure software-import processes.
• Familiarity with TDM, serial circuits, and specialized communications technologies.
