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.

Sound Engineering Technicians

Designing and operating Navy band concert systems, mixing live feeds, managing monitor mixes, and calibrating outputs transfer directly to live-performance sound work.

How to prepare: Build a work-sample portfolio showing a concert system setup, signal routing, monitor mix plan, and output calibration results.

What the civilian work involves
  • Confer with producers, performers, and others to determine and achieve the desired sound for a production, such as a musical recording or a film.
  • Set up, test, and adjust recording equipment for recording sessions and live performances.

Audio and Video Technicians

Configuring, maintaining, and troubleshooting concert audio systems provides a practical foundation for multimedia equipment setup and fault diagnosis.

How to prepare: Practice setting up a hybrid presentation that routes microphones and playback audio through Zoom while integrating video and testing for feedback and routing faults.

What the civilian work involves
  • Diagnose and resolve media system problems.
  • Install, adjust, and operate electronic equipment to record, edit, and transmit radio and television programs, motion pictures, video conferencing, or multimedia presentations.
Civilian tools and software (examples)
