• Diagnose, troubleshoot, maintain, and repair Ford Super Duty trucks, including 6.7L Power Stroke diesel engines.
• Perform diagnostics and repairs on medium- and heavy-duty commercial trucks, including Peterbilt.
• Diagnose electrical, electronic, engine, transmission, fuel, emissions, and drivetrain systems.

• Significant professional experience in diesel and commercial truck repair.
• Strong diagnostic and repair experience with Ford Power Stroke diesel engines.
• Proven ability to work on medium- and heavy-duty trucks.

Who We’re Looking For

We value experience, sound judgment, and genuine mechanical ability. The right candidate is someone who can confidently approach an unfamiliar problem, develop a logical diagnostic plan, and see the repair through to completion. We want a technician who takes pride in their tools, their workspace, and the quality of their work. Someone who understands that keeping a fleet operating requires more than turning wrenches — it requires attention to detail, accountability, and the ability to solve problems correctly the first time.

What You Can Expect

• A diverse fleet with challenging and rewarding repair work.
• A dedicated helper to assist with daily repairs and maintenance.
• Direct communication with the Shop Manager.
• An opportunity to serve as the senior technical resource for the on-road fleet.
