Warranty & Diagnostics Technician

Warranty & Diagnostics Technician Position Overview

FR Conversions LLC is seeking two experienced Warranty & Diagnostic Technicians to support post‑delivery quality and field service for our fleet of converted ambulances, mini‑buses, and specialty mobility vans.

The role requires comfort working without standard repair templates and the ability to troubleshoot systems where OEM platforms interface with custom electrical and mechanical upfits. When not actively supporting warranty vehicles, the technician performs Pre‑Delivery Inspections (PDI) on completed stock units to identify and correct issues before customer delivery, directly reducing downstream warranty events.

Most work is performed on‑site in Westminster, with field service required periodically based on customer need.
