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

Planned and corrective maintenance, built-in fault isolation, and modular repair of gun computer and electro-optical equipment transfer directly to electronic equipment troubleshooting and repair.

How to prepare: Complete a hands-on industrial electronics troubleshooting course that includes external test equipment and post-repair functional checks.

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.
  • Install repaired equipment in various settings, such as industrial or military establishments.
Civilian tools and software (examples)
  • Circuit evaluation software
  • Computerized maintenance management system CMMS

Electrical and Electronic Engineering Technologists and Technicians

Equipment testing, alignment, fault isolation, and component replacement provide a direct foundation for electronics technician work supporting system performance testing.

How to prepare: Build a bench-test project using a schematic and external test instruments, documenting fault diagnosis, component replacement, and final performance results.

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.
