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

Shipboard experience diagnosing faults and making minor electrical, electronic, and servo system repairs transfers to industrial equipment troubleshooting.

How to prepare: Take a hands-on industrial electronics troubleshooting course to practice diagnosing faults and testing repaired equipment beyond torpedo tube systems.

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.
  • Set up and test industrial equipment to ensure that it functions properly.
  • Inspect components of industrial equipment for accurate assembly and installation or for defects, such as loose connections or frayed wires.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS
