Hiring Manager
Ryder System
Dear Hiring Manager,
Ryder's commitment to reliable logistics depends on technicians who can diagnose and repair under pressure. In my current role at Corliss Resources, I keep 40 trucks compliant and on the road without incident. That means thorough inspections, proactive maintenance, and training apprentices to the same standards I uphold.
I specialise in keeping diesel fleets operational through preventive maintenance and efficient repairs. Last quarter, I completed 80+ PM inspections and reduced unscheduled breakdowns by 30% through diagnostic work that identified issues before they became expensive.
Communication is also key in a busy shop. I coordinate repair schedules with drivers, dispatch, and parts suppliers, ensuring everyone knows timelines and expectations. My leadership of two apprentices has them on track to meet certification deadlines while reinforcing our safety culture.
