Dyno Technician — Test Assistant through Dyno Lead / Test Engineer-Technician (Levels 1–4)

Riggs Cat Power & Energy is hiring Dyno Technicians at every level, from Test Assistant to Dyno Lead / Test Engineer-Technician. You will test rebuilt and serviced engines before they return to service, validating horsepower, torque, and break-in against OEM spec and flagging units for rework. This is not an entry role: at least 2 years of commercial diesel or large-bore engine experience is required to start.

The dyno is the final quality checkpoint after rebuild, working hand in hand with our Engine Rebuild and Transmission teams. Client First and Integrity lead here: the test sheet is what the client trusts, and senior techs run client witness tests face to face. Every level lives the Riggs Way: Urgent. Selfless. Excellent.

The shop's authority on test standards and performance data. Here's what changes from Senior:

• Scope: Decides what returns to service and what goes back for rework across the shop
• Standards: Sets test procedures and acceptance criteria per engine family, including new families the shop takes on, instead of working to written procedures
• Equipment: Owns dyno calibration and maintenance, plus instrumentation and calibration management
• Client witness tests: Sets witness test procedures and handles escalated tests, including when an engine misses spec in front of the client
• Rebuild lines: Tracks failure trends, feeds them back to the rebuild lines, and keeps the lines working with the test team
• People: Trains dyno staff
• Client role: Presents results clearly to non-technical clients

Level 4 is the top of the ladder.
