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.

Electrical and Electronic Engineering Technologists and Technicians

Fault isolation and corrective maintenance on announcing-system power supplies, digital matrices, audio amplifiers, and control computers transfer directly to electronics maintenance and diagnostic work.

How to prepare: Complete a hands-on electronics diagnostic lab that includes schematic reading, component testing, and documenting a repair, then target maintenance-focused technician openings.

What the civilian work involves
  • Modify, maintain, or repair electronics equipment or systems to ensure proper functioning.
  • Replace defective components or parts, using hand tools and precision instruments.
  • Set up and operate specialized or standard test equipment to diagnose, test, or analyze the performance of electronic components, assemblies, or systems.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Maintaining telephone interfaces, control computers, and networked announcing-system configurations provides a foundation for troubleshooting civilian communications equipment.

How to prepare: Take a hands-on telecommunications equipment course covering circuit testing, telephone and data connections, and post-installation verification.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
  • Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks.
