Generator Diesel Technician

About the Role

As a Diesel Engine Shop Technician at W.W. Williams, you’ll perform overhauls, rebuilds, and failure analysis on diesel and gaseous engines in our shop. This is a bench-based position with no field calls or service truck—just quality work on the bench with an experienced team behind you.

Responsibilities

• Disassemble, inspect, evaluate, and rebuild diesel and gaseous engines from teardown to reassembly in the shop.
• Perform accurate failure analysis and troubleshooting using electronic diagnostic tools.
• Determine parts requirements and qualify components for reuse per manufacturer reusability guidelines.
• Build a repair plan—operations and estimated repair hours—and document parts and labor accurately on work orders.
• Clean, inspect, and recondition components; complete clear inspection and teardown reports.
• Load-test rebuilt engines and verify performance before return to the customer.
• Service supporting systems—fuel, cooling, lubrication, air, and electrical.
• Keep a safe, clean, organized work area and follow all company, safety, and EPA standards.

Requirements

• 2+ years of diesel engine repair and overhaul experience, or equivalent training and experience.
• Experience with Cat, Cummins, John Deere, Isuzu, or MTU engines is a plus.
• Knowledge of A/C and D/C systems and engine diagnostics/troubleshooting.
• Basic computer skills with the ability to use diagnostic programs.
• One or more factory/OEM certifications preferred—company-paid training is available to grow them.
• Your own hand tools (we back you with a Tool Replacement Insurance program).

Transitioning military, trade-school graduates, and apprentice-level techs ready to grow are encouraged to apply.
