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

Installing wideband communications equipment, isolating component faults, and checking circuit quality transfer directly to telecommunications equipment installation and repair.

How to prepare: Practice installing and fault-testing a small civilian communications network, documenting the fault, corrective action, and verification results.

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

Radio, Cellular, and Tower Equipment Installers and Repairers

Tuning, aligning, testing, and restoring troposcatter and satellite link equipment provide transferable experience for radio transmission equipment work.

How to prepare: Complete practical training in civilian transmission-line sweep testing and antenna installation inspection.

What the civilian work involves
  • Inspect completed work to ensure all hardware is tight, antennas are level, hangers are properly fastened, proper support is in place, or adequate weather proofing has been installed.
  • Test operation of tower transmission components, using sweep testing tools or software.
  • Install all necessary transmission equipment components, including antennas or antenna mounts, surge arrestors, transmission lines, connectors, or tower-mounted amplifiers (TMAs).

Electrical and Electronic Engineering Technologists and Technicians

Component-level diagnosis, faulty-part replacement, and communications-system modification transfer to electronics testing and repair assignments.

How to prepare: Build a bench-test portfolio showing fault isolation, component replacement, and post-repair performance measurements on a civilian electronic assembly.

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.
