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 Installers and Repairers, Transportation Equipment

Organizational-level maintenance of shipboard sonar, sounding, and sonar communications equipment provides directly relevant experience maintaining transportation electronics.

How to prepare: Complete a hands-on electronics repair lab covering circuit fault isolation and post-repair testing to bridge sonar subsystem maintenance to broader transportation equipment.

What the civilian work involves
  • Inspect and test electrical systems and equipment to locate and diagnose malfunctions, using visual inspections, testing devices, and computer software.
  • Reassemble and test equipment after repairs.
