About the Position

Position Summary

Precision Diesel & Machinery LLC is seeking an experienced Diesel Technician 3 with demonstrated proficiency in EPA Tier 3 and Tier 4 emissions systems. This is a full-time, hands-on technical position working on Class 4–8 commercial trucks, agricultural equipment, and heavy machinery at our Yakima, WA shop.
