Network Engineer-Mid Level

The Mid-Level Network Engineer designs, configures, secures, and sustains network infrastructure supporting Department of Defense tactical and enterprise environments. The engineer will implement routing, switching, firewall, virtual local area network, wireless, and network-management solutions; monitor performance and availability; troubleshoot complex connectivity issues; and maintain accurate technical documentation. Success requires independent technical judgment, disciplined configuration management, and close coordination with cybersecurity, systems engineering, operations, and program stakeholders.

Role Priorities

• Deliver secure, resilient, and high-performing network services for mission and business operations.

• Maintain standardized configurations, accurate documentation, and strong change control across network environments.

• Identify and resolve performance, availability, interoperability, and security issues before they affect users or mission outcomes.

• Support modernization while maintaining compliance with approved Department of Defense cybersecurity and engineering requirements.

• Provide stakeholders with timely technical analysis, clear recommendations, and reliable status information.

Key Responsibilities

Network Engineering and Implementation

• Design, configure, test, and deploy network solutions using routers, switches, firewalls, virtual local area networks, wireless technologies, and associated services.

• Configure and manage dynamic routing protocols, switching features, access controls, network address translation, and segmentation for tactical and enterprise environments.

• Evaluate technical requirements, network dependencies, capacity constraints, and implementation risks; recommend practical solutions aligned with approved architectures.

Operations, Security, and Troubleshooting

• Monitor network health, availability, utilization, and performance; investigate incidents and restore service within established priorities.

• Troubleshoot complex Layer 2 and Layer 3 connectivity, routing, switching, firewall, wireless, and interoperability issues using approved diagnostic tools.

• Implement network hardening, security controls, and remediation actions in accordance with approved Security Technical Implementation Guides and organizational policy.

• Support cryptographic devices and protocols used in defense network environments, coordinating with security specialists when escalation is required.

Configuration Management and Collaboration

• Maintain network diagrams, configuration baselines, addressing plans, interface records, standard operating procedures, and implementation documentation.

• Use network monitoring and configuration-management tools to identify drift, support backups, control changes, and improve operational visibility.

• Participate in technical reviews, change-control boards, testing events, and implementation activities; document decisions, risks, and follow-up actions.

• Coordinate with cybersecurity, systems engineering, operations, vendors, and customer stakeholders to integrate solutions and resolve cross-functional impediments.
