Shop Operations Supervisor​/Lead Diagnostic Foreman

Why this role exists

We’re rebuilding and growing our service department. We need a hands‑on diagnostic leader who can bring structure to the shop floor: diagnose trucks correctly, map the repair path, dispatch work to the right technician, and drive quality and accountability—so our Service Manager can focus on customer relationships and bringing in more work.

This role is the communication hub between technicians, advisors, and parts, ensuring repairs are completed properly, efficiently, and safely.

• Diagnose incoming work and perform/assign triage for all service work.
• Build the repair plan and determine the best technician for each job.
• Provide technical guidance, coaching, and hands‑on help to technicians as needed to complete repairs correctly.

• Own the workflow and daily communication between technicians, service advisors, and parts.
• Run daily huddles (10–25 minutes) to plan the day: review open work, promised times, parts/approval issues, and upcoming appointments.
• Practice real‑time shop management: frequent floor walks to verify status, catch issues early, and remove bottlenecks (skills, parts, tools, technical support).
• Update priorities and communicate changes quickly when a job is off track, needs escalation, or requires rescheduling.

• Final review/sign‑off on completed repair orders: confirm the work is complete, documentation is accurate, and road tests are performed when required.
• Own end‑of‑process quality checks and quickly redirect failed QC work to the right technician to minimize downtime.
• Drive accurate technician notes and clean documentation standards so there is a clear story of what was found and what was fixed.

• Coordinate closely with Parts; ensure warranty/core parts are handled correctly.
• Maintain a safe, clean shop environment and follow regulations.
• Maintain tool and diagnostic equipment control and accountability.

• Help ensure the shop is staffed correctly for quality and throughput.
• Participate in technician recruiting, interviewing, and onboarding.
• Coach technicians up—or make changes when needed. This role includes the responsibility to hire and/or terminate technicians (in coordination with leadership) to ensure we have the right team to deliver quality repairs.

• Use modern diagnostic workflows, including AI‑assisted diagnostic tools, to speed root‑cause analysis and improve first‑time‑fix accuracy—while applying sound mechanical judgment and safe repair practices.

• Valid Class A CDL (or willing to obtain if not currently held).
• 5+ years of medium/heavy‑duty truck repair experience.
• Strong technical knowledge and diagnostic problem‑solving ability.
• Strong communication and organization skills; ability to lead and support technicians.
• Ability to road test vehicles as needed to diagnose and verify repairs.
• Ability to speak Spanish fluently.

• Familiarity with OEM and warranty processes and dealership operations.
• Comfort driving workflow discipline: clear documentation, daily planning, and real‑time floor management.
• Familiarity with CDK.
