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 Electronics Repairers, Commercial and Industrial Equipment

TTWCS fault isolation, repair, and operational readiness testing transfer directly to diagnosing and restoring industrial electronic equipment.

How to prepare: Complete hands-on training in industrial electronic troubleshooting that includes recording faults, repairs, and test results in a maintenance log.

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.
  • Maintain equipment logs that record performance problems, repairs, calibrations, or tests.
  • Set up and test industrial equipment to ensure that it functions properly.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Electrical and Electronic Engineering Technologists and Technicians

Operating TTWCS test equipment and troubleshooting system failures provides a foundation for electronics testing and repair in engineering support roles.

How to prepare: Take a practical electronics lab course focused on reading schematics and using test equipment to diagnose component and assembly faults.

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