Sage Rental Services is seeking an experienced Diesel Mechanic to join our team and maintain, troubleshoot, and repair diesel-powered equipment used in industrial pump rental, dewatering, and bypass applications.

This position is primarily focused on diesel engine maintenance and repair, including preventive maintenance, troubleshooting, and replacement of common engine components such as starters, alternators, fuel pumps, and related systems. The ideal candidate has hands‑on experience working on diesel engines and understands the importance of keeping equipment reliable, safe, and ready for operation.

Experience with pumps and pump systems is a plus, but not required. We are looking for someone with a strong diesel mechanical background, good organizational skills, and the ability to create, manage, and complete work orders accurately.

This position also includes a rotating on‑call schedule for after‑hours and weekend service needs.

• Perform routine preventive maintenance (PM) on diesel engines and diesel‑powered equipment.
• Diagnose, troubleshoot, and repair diesel engine issues.
• Replace and repair common engine components, including starters, alternators, fuel pumps, belts, filters, and related parts.
• Perform basic electrical and mechanical troubleshooting on diesel‑powered equipment.
• Inspect equipment and identify maintenance needs before failures occur.
• Create, update, and close work orders with accurate descriptions of repairs, labor, parts used, and maintenance performed.
• Manage work orders to ensure repairs are completed, documented, and communicated properly.
• Maintain accurate service records and equipment maintenance histories.
• Assist with troubleshooting and repairs on pumps and associated equipment as needed.
• Respond to service calls during assigned on‑call rotations, including evenings and weekends.
• Maintain a clean, organized, and safe work area.
• Follow company safety procedures and equipment maintenance standards.

• Demonstrated hands‑on experience repairing and maintaining diesel engines is required.
• Experience performing diesel engine preventive maintenance and troubleshooting.
• Working knowledge of diesel engine components and common mechanical failures.
• Ability to diagnose and repair issues involving starters, alternators, fuel systems, and related engine components.
• Experience creating, documenting, and managing work orders or maintenance records.
• Must provide and maintain your own mechanic's tools and toolbox.
• Valid driver's license and a good driving record.
• Ability to work independently, troubleshoot problems, and manage multiple repair priorities.
• Willingness to participate in a rotating on‑call schedule, including nights and weekends when assigned.

• Experience maintaining diesel‑powered pumps, industrial equipment, generators, or rental equipment.
• Familiarity with centrifugal pumps, trash pumps, or dewatering equipment.
• Experience with diesel engine diagnostic tools and basic electrical testing.
• Experience working in industrial, construction, equipment rental, or field service environments.

Pump experience is a plus, not a requirement. Strong diesel engine repair experience is the priority.
