Network Network Engineer Jobs in Alabama (NOW HIRING)

Job Title: Principal Network Engineer

Reliable and secure enterprise networks are essential to the Air Force's ability to communicate, collaborate, and execute missions across a globally distributed environment. This position supports the Air Force Intranet Control (AFINC) III program by providing senior-level network engineering and technical infrastructure expertise supporting complex Air Force enterprise network environments.

Working alongside Government personnel and enterprise network teams, you will help design, optimize, secure, and troubleshoot mission-critical network infrastructure while supporting continued modernization of Air Force network capabilities. This position requires deep hands-on networking expertise and the ability to solve complex infrastructure problems across large-scale environments where availability, performance, security, and mission continuity are critical.

In this role, you will provide senior technical leadership supporting enterprise network architecture, engineering, automation, troubleshooting, and infrastructure modernization. Responsibilities include, but are not limited to:

• Design, implement, configure, and troubleshoot complex enterprise network architectures and infrastructure.
• Analyze and simulate network traffic to identify performance issues, isolate faults, evaluate proposed solutions, and support problem resolution.
• Develop and test network configurations within virtual and physical laboratory environments prior to enterprise implementation.
• Install, configure, troubleshoot, upgrade, patch, secure, and harden enterprise network devices including routers, switches, serial consoles, load balancers, and associated infrastructure.
• Diagnose complex network connectivity, routing, switching, performance, availability, and interoperability issues.
• Evaluate existing network infrastructure, identify performance or capability gaps, and recommend technical solutions that improve reliability, security, scalability, and mission effectiveness.
• Develop, execute, modify, and maintain scripts used to automate network engineering, administration, configuration, and operational tasks.
• Support network automation initiatives that reduce manual processes, improve configuration consistency, and increase operational efficiency.
• Support enterprise network monitoring and management using automated network management and performance-monitoring solutions.
• Apply cybersecurity principles to network architecture and infrastructure, including routers, switches, firewalls, servers, endpoints, load balancers, and Intrusion Detection Systems (IDS).
• Evaluate network configurations and architecture for security vulnerabilities, configuration weaknesses, and compliance with applicable Department of Defense requirements.
• Support Software Defined Networking (SDN) and other network modernization initiatives as required.
• Perform technical analysis supporting network changes, upgrades, technology refreshes, and infrastructure modernization efforts.
• Collaborate with cybersecurity, systems administration, application, infrastructure, and operations teams to resolve complex enterprise-level technical issues.
• Review and document activities associated with incidents, problems, and change requests to maintain configuration awareness, support audits and investigations, and reduce repeat troubleshooting efforts.
• Develop technical documentation, network diagrams, configuration information, procedures, and engineering recommendations.
• Provide senior-level technical guidance and troubleshooting support to Government personnel and other network engineering professionals.
• Communicate complex network issues, technical risks, and recommended solutions clearly to both technical and non-technical stakeholders.
