Warranty & Diagnostics Technician

About the role

FR Conversions LLC is seeking two experienced Warranty & Diagnostics Technicians to support post-delivery quality and field service for our fleet of converted ambulances, mini-buses, and specialty mobility vans. This is a senior, hands-on technical role designed for individuals who can step into complex diagnostic and repair work with minimal training. The Warranty & Diagnostics Technician serves as a technical problem-solver and escalation resource, responsible for diagnosing and resolving mechanical, electrical, and structural issues on low-volume, highly customized vehicles. This 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, this role performs Pre-Delivery Inspections (PDI) on completed stock units to ensure issues are identified and corrected 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. PDI work is performed as needed to support delivery schedules and reduce future warranty events. FR Conversions is a mission-driven company delivering high-quality, accessible, and life-saving transportation solutions. This role offers experienced technicians autonomy, complexity, and meaningful work without the constraints of flat-rate dealership environments.
