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.

Telecommunications Equipment Installers and Repairers, Except Line Installers

Diagnosis and repair of telephony, wired and wireless network devices, optical transmission systems, and communications equipment transfer directly to telecommunications equipment maintenance.

How to prepare: Complete a hands-on lab that installs a small data network, introduces equipment faults, and documents troubleshooting and post-repair checks.

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.
Civilian tools and software (examples)
  • Cisco IOS

Electrical and Electronic Engineering Technologists and Technicians

Complex field repairs, equipment modifications, and restoration of electronic and electromechanical systems align with electronics technician troubleshooting and maintenance work.

How to prepare: Build a bench-test work sample showing schematic interpretation, fault isolation, component replacement, and verification that the repaired equipment functions correctly.

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.
