Step into a day where your expertise keeps critical fleets moving
It’s sunrise on the Big Island or Oahu. You roll out in a fully outfitted utility service truck—crane swinging into place, welder and compressor ready, laptop booted—headed to a jobsite where a bucket truck needs to be back online before crews start. You diagnose, repair, and verify. A quick call with the customer, a note in the repair order, and you’re on to the next challenge. That’s a typical day as a Field Service Technician with Custom Truck One Source (CTOS), a 30-year industry leader with 40+ locations across the U.S. and Canada.

- Perform inspections, preventive maintenance, and field diagnostics to minimize downtime.
- Interpret schematics, manuals, and repair orders to plan effective fixes.
- Use laptops and diagnostic software to pinpoint issues accurately.
- Document all work precisely: repair orders, timecards, inspection forms.
- Coordinate with customers and CTOS teams to schedule and complete work efficiently.
- Comply with all safety, environmental, DOT/ANSI, and regulatory standards.

- Engage in ongoing CTOS and OEM training to sharpen your craft.
