  • Local and remote UUV watch
  • Organizational-level underwater vehicle maintenance
  • UUV sortie planning and post-mission analysis

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.

ROV Pilot Technician

UUV launch and recovery, local or remote watch, and organizational-level maintenance provide an operational foundation for subsea ROV work.

How to prepare: Seek employer-led training in tethered ROV control, manipulator tooling and offshore operating scenarios. Oceaneering seeks technical training or industry experience in a mechanical, electronic or electrical discipline, so ask how your maintenance background meets its entry expectations and what offshore requirements apply.

What the civilian work involves
  • The pilot flies the ROV, and operates the manipulator and/or specialized tooling to complete the assigned task.

Electro-Mechanical and Mechatronics Technologists and Technicians

Organizational-level UUV maintenance provides a foundation for electromechanical equipment maintenance, making this the maintenance-focused alternative to ROV operations.

How to prepare: Complete a hands-on electromechanical troubleshooting course that includes schematic reading and bench testing with voltmeters and oscilloscopes.

What the civilian work involves
  • Test performance of electromechanical assemblies, using test instruments such as oscilloscopes, electronic voltmeters, or bridges.
  • Read blueprints, schematics, diagrams, or technical orders to determine methods and sequences of assembly.
  • Modify, maintain, or repair electrical, electronic, or mechanical components, equipment, or systems to ensure proper functioning.
