Proven Performance – Coos Bay, OR

Proven Performance is looking for a skilled diesel technician to join our team. We’re a well-established diesel performance and repair shop with 11+ years in business, a strong local reputation, and a shop that works on everything from daily drivers to 1,400+ horsepower race trucks.

What you’ll be doing:
• Diagnosing and repairing diesel trucks
• Engine work, maintenance, and performance upgrades

• Diesel experience (professional or strong hands-on background)
• Ability to diagnose, not just replace parts
• Pride in workmanship and attention to detail
• Reliability and a good attitude — drama-free shop
• Performance experience is a big plus, but not required

What we offer:
• Competitive pay (based on experience)
• Consistent work year-round
• Clean, well-equipped shop
• Work on high-performance and race trucks
• A team that actually knows diesels and takes pride in what we build

📍 Location: Coos Bay, Oregon
📩 Apply: Stop by the shop, call us, or message Proven Performance directly

If you’re tired of flat-rate headaches or working at a shop that cuts corners, come work somewhere that builds things right
