Job description

Solve the puzzle. Teach the team. Keep the fleet moving.

Butler County RTA is hiring a master-level Diagnostician / Mechanic Trainer, the person who figures out what’s really wrong, spells out exactly how to fix it, and makes every technician around them sharper in the process. This isn’t a production wrench role. It’s a diagnostic and teaching role for someone who has seen it all in the heavy-duty world and wants their expertise to multiply across a whole shop.
If you’ve spent years under buses and trucks, you know Cummins powertrains inside and out, and you get a kick out of mentoring the next generation of techs, this is your seat.

What you’ll do

• Be the shop’s go-to diagnostician who chases down the faults nobody else can crack, from Cummins powertrain and aftertreatment issues to electrical, electronic, and hydraulic gremlins.
• Scope the work before the wrench turns. You’ll identify the root cause, the parts, and the exact service tasks so jobs are packaged and ready to assign the moment a technician and a bus are free.
• Work shoulder-to-shoulder with service writers and technicians, turning your diagnosis into a clean, executable work order.
• Teach. Coach. Level up the team. You’ll build the diagnostic skill of every technician and service writer around you, hands-on and by example.
• Get your hands dirty when it counts: road-testing, verifying repairs, and confirming vehicles are safe to return to service.
• Help us cut downtime by pre-staging parts and catching recurring failures before they park a bus.

Who you are

• You’ve got serious time in the bus or truck world, and heavy-duty diesel is your home turf.
• You know Cummins powertrains cold: engines, aftertreatment, and emissions.
• Motorcoach experience? That moves you to the top of the stack.
• You’d rather solve the puzzle than just turn the bolt, and you love showing others how you did it.
• You’re fluent with diagnostic tools and software (Cummins INSITE, J1939/J1587, and the like).
• CDL with appropriate endorsements, or the ability to get one. ASE and OEM/Cummins certifications are a big plus.

Benefits & Compensation

• $36.00 to $44.63 per hour, depending on experience (non-exempt, overtime-eligible)
• 14% employer contribution to the Ohio Public Employees Retirement System (OPERS)
• Medical, dental, vision, life insurance, and short-term disability benefits
• Generous Paid Time Off, 29+ days per year
• Stable, year-round employment with consistent hours
• Employer-provided uniforms
• Supportive leadership and team-oriented culture
