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, engineering, operating, and evaluating command information systems and their tactical-to-strategic interfaces transfers to civilian network architecture and network improvement work.

How to prepare: Build a civilian network design portfolio example that documents connectivity requirements, routing choices, and an upgrade plan.

What the civilian work involves
  • 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

Planning, installing, and evaluating transmission, switching, radio, microwave, and satellite systems transfers directly to telecommunications system assessment and modification work.

How to prepare: Create a sample telecommunications upgrade proposal with a requirements matrix, a system diagram, and an installation sequence.

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
