Overview

A Network Engineering Officer analyzes, designs, deploys, maintains, and manages network infrastructure that enables command and control. The officer plans and budgets network work, directs secure integration and quality control, and manages routing, switching, circuits, transport, encryption, cybersecurity boundaries, monitoring, and connectivity across deployed and garrison networks.

Minimum clearance: Secret, often with SCI exposure

Core Skills

  • Joint and coalition network integration
  • Cable planning and circuit provisioning
  • Network quality of service optimization
  • Encryption management and boundary cybersecurity

Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Computer Network Architects

Designing and securely integrating enterprise networks, managing routing and switching, and directing network performance transfer directly to civilian network architecture.

How to prepare: Build a civilian network design portfolio using a fictional enterprise, with routing choices, quality of service settings, boundary controls, and a tested troubleshooting scenario.

What the civilian work involves
  • Develop or recommend network security measures, such as firewalls, network security audits, or automated security probes.
  • Develop and implement solutions for network problems.
  • Coordinate network operations, maintenance, repairs, or upgrades.
Civilian tools and software (examples)
  • Border Gateway Protocol BGP
  • Ansible software

Telecommunications Engineering Specialists

Cable-plan management, circuit provisioning, transport planning, and technical analysis of communications architectures support civilian telecommunications system upgrades.

How to prepare: Prepare a sample facility telecommunications upgrade plan with a cable layout, circuit requirements, and an implementation diagram in Microsoft Visio.

What the civilian work involves
  • Consult with users, administrators, and engineers to identify business and technical requirements for proposed system modifications or technology purchases.
  • Implement system renovation projects in collaboration with technical staff, engineering consultants, installers, and vendors.
  • Assess existing facilities' needs for new or modified telecommunications systems.
Civilian tools and software (examples)
  • Microsoft Visio
  • Autodesk AutoCAD

Information Security Engineers

Boundary cybersecurity, encryption management, network monitoring, and secure network integration provide a foundation for engineering and assessing network security controls.

How to prepare: Build an isolated network-security lab and document how you detect intrusions and measure the effectiveness of its security controls.

What the civilian work involves
  • Coordinate monitoring of networks or systems for security breaches or intrusions.
  • Assess the quality of security controls, using performance indicators.
  • Scan networks, using vulnerability assessment tools to identify vulnerabilities.
Civilian tools and software (examples)
  • Linux
  • Bash
