Job Responsibilities

As a Heavy Mobile Equipment Mechanic (WG-10), your primary objective is to maintain, troubleshoot, modify, and overhaul a variety of heavy-duty vehicles and support machinery. You will work on an array of vehicles, including bulldozers, road graders, fuel-dispensing trucks, massive snow-removal equipment, and tactical fire protection vehicles.

Key responsibilities of this role include:

Assembly and Installation: Dismantling, assembling, aligning, and installing mechanical assemblies and systems on heavy mobile machinery.
System Diagnostics: Troubleshooting complex mechanical systems to isolate malfunctions and identify the scope of repairs required. This involves assessing diesel engines, multi-stage transmissions, complex power transfer systems, and high-pressure hydraulic frameworks.

Tool Maintenance: Safely operating and maintaining heavy hand tools, pneumatic machinery, welding apparatus, and specialized power tools designed for heavy equipment maintenance.

For this WG-10 position, you must demonstrate the ability to perform the duties of the position without normal supervision.

U.S. Citizenship: Applicants must be citizens of the United States.
Suitability/Fitness Adjudication: Candidates must successfully pass a background suitability investigation.
