Job summary

Butler County RTA is seeking a master-level Diagnostician / Mechanic Trainer to diagnose complex heavy-duty issues, define exact fixes, and elevate the skills of every technician in the shop. If you’ve spent years under buses and trucks, particularly with Cummins powertrains, you’ll fit right in.

This is a teaching, not a production role. You’ll road-test, verify repairs, mentor staff, and help pre-stage parts to cut downtime while keeping safety and compliance at the forefront.

Qualifications

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

Responsibilities

• Diagnose faults nobody else can crack, from powertrain to electrical and hydraulic gremlins.
• Scope work at the outset: identify root causes, parts, and exact service tasks for ready-to-run jobs.
• Create clean, executable work orders from diagnosis in collaboration with writers and technicians.
• Teach and mentor the team, improving diagnostic skills across the shop.
• Road-test and verify repairs, ensuring vehicles are safe to return to service.
• Help cut downtime by pre-staging parts and spotting recurring failures.

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
