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.

Petroleum Pump System Operators, Refinery Operators, and Gaugers

Operating fuel pumps, electric valves, tank level controls, and manifolds transfers directly to petroleum pumping and tank-transfer operations.

How to prepare: Complete introductory SCADA training focused on monitoring tank levels and controlling pump and valve operations.

What the civilian work involves
  • Maintain and repair equipment, or report malfunctioning equipment to supervisors so that repairs can be scheduled.
  • Monitor process indicators, instruments, gauges, and meters to detect and report any possible problems.
  • Start pumps and open valves or use automated equipment to regulate the flow of oil in pipelines and into and out of tanks.
Civilian tools and software (examples)
  • Supervisory control and data acquisition SCADA software
  • Programmable logic controller PLC software

Industrial Machinery Mechanics

Repairing and adjusting pumps, valves, filters, and meters provides directly relevant experience for industrial equipment maintenance.

How to prepare: Build a repair portfolio documenting pump and valve faults, corrective work, and adjustments for applications to industrial maintenance positions.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Clean, lubricate, or adjust parts, equipment, or machinery.
