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.

Avionics Technicians

Intermediate-level inspection, testing, and repair of aviation electronic modules, circuit boards, and cables directly overlap avionics component repair work.

How to prepare: Build a repair-work portfolio describing component faults, test results, and completed repairs, and use it to target avionics bench-repair openings.

What the civilian work involves
  • Test and troubleshoot instruments, components, and assemblies, using circuit testers, oscilloscopes, or voltmeters.
  • Adjust, repair, or replace malfunctioning components or assemblies, using hand tools or soldering irons.
  • Keep records of maintenance and repair work.

Electrical and Electronics Repairers, Commercial and Industrial Equipment

Testing and repairing electronic modules, printed-circuit boards, and cables transfers to diagnosing and repairing electronic components in commercial and industrial equipment.

How to prepare: Complete equipment-specific troubleshooting practice for the industrial product line you intend to service, including its test procedures and repair logs.

What the civilian work involves
  • Test faulty equipment to diagnose malfunctions, using test equipment or software, and applying knowledge of the functional operation of electronic units and systems.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
