About Grit One
Grit One is Midwest Salt with a port address. For almost 40 years, Midwest Salt has kept roads safe across the Midwest with top-quality product, competitive pricing, and on-time delivery. Grit One is where that supply chain starts. Vessels and barges unload at our Port of Chicago terminal, product gets stockpiled, and it moves out fast to the customers who count on us every winter. You get the stability of an established company and the energy of a growing operation. Our port is expanding, and the people we hire now will help build it.

About the Role
We're hiring a hands-on maintenance mechanic to keep our Chicago terminal running: mobile equipment, material-handling conveyors, and Class 8 trucks. This is a broad, single-owner role. You'll be as comfortable diagnosing a wheel loader as you are tracking a belt or changing a truck tire. If you like variety and owning the equipment end to end, this one's for you.

Reporting to the Plant Manager  you'll be the go-to person for keeping every piece of equipment safe, reliable, and ready to work.

• Conveyor Maintenance: Service belt conveyors, including tracking, splicing, idlers, pulleys, bearings, gearboxes, and drive motors.
• Diagnostics & Troubleshooting: Diagnose mechanical, hydraulic, pneumatic, and basic electrical faults, and return equipment to service safely and quickly.

• Preventive Maintenance: Carry out the preventive-maintenance schedule, including routine oil, filter, and fluid changes on diesel engines and drivetrains, greasing, and truck tire changes, rotations, and repairs.
• Welding & Fabrication: Perform light welding and fabrication as needed.
• Records & Documentation: Keep accurate equipment and repair records. Fill out and submit repair orders and all related paperwork.
• Safety & Compliance: Follow all safety and lockout/tagout procedures and support a safe working environment.

• ASE Medium/Heavy Truck (T-series) certifications.
