Mobile Diesel Technician (Overnight)

Be the certified backbone of a growing fleet operation — diesel expertise plus the inspection authority that keeps us legal, in the field and in the shop.

About Hermont Hermont is a Canadian fleet maintenance company expanding into Texas. We keep commercial delivery vehicles safe, compliant, and on the road for national last-mile delivery operations — handling preventive maintenance, DOT inspections, and mobile repair so their fleets are ready to run every single day. San Antonio is one of our first Texas markets, with Austin close behind — so the people we bring on now get in at the ground floor of our U.S. growth, with room to grow as we do.

The role This is our senior technician role, and it works both ways: out in the field in a company-provided service vehicle keeping our diesel step vans and delivery trucks running, and in our central shop handling heavier repairs and the inspections that keep us compliant. You'll perform DOT/FMCSA annual inspections, and — with a Texas commercial inspector certification we'll help you obtain — the Texas state inspections that keep our fleet legally road-ready. You'll work overnight and be a go-to for complex diagnostics.

What you'll do

• Perform preventive maintenance, diagnostics, and repairs on diesel and heavier commercial vehicles (step vans, delivery trucks), both on-site (mobile) and in the shop
• Drive a company-provided service vehicle to our hubs to service vehicles in the field
• Conduct DOT/FMCSA annual (periodic) inspections and document them to standard
• Perform Texas commercial vehicle safety inspections at our licensed shop (with certification)
• Handle brake work to inspection standards, along with engine, drivetrain, and electrical repairs
• Decide what can be handled in the field vs. brought into the shop for heavier work or state inspection
• Support and mentor other technicians on complex jobs
• Keep detailed, compliant maintenance and inspection records

What we're looking for

• 5 years of diesel or medium/heavy-duty vehicle repair experience
• Qualified to perform DOT/FMCSA annual inspections (training experience per 49 CFR 396.19)
• A Texas commercial vehicle inspector certification, OR the willingness and eligibility to obtain one — we sponsor and support your certification
• Comfort working independently in the field as well as in a shop
• Willingness to work overnight hours
• Valid driver's license and clean driving record (required — you'll drive a company vehicle)
• Your own hand tools (we supply specialty and diagnostic equipment)

Nice to have

• A current Texas commercial vehicle inspector certification (top of pay range)
• ASE certification(s), including diesel/medium-heavy truck
• Brake inspector qualification (49 CFR 396.25)
• CDL (Class A or B)
• Electric vehicle (EV) / high-voltage experience
• Delivery, fleet, or last-mile maintenance experience

Compensation & time off

• $28.00–$38.00/hour, based on experience
• $3.00/hour overnight shift differential
• Company-provided service vehicle
• Paid time off and paid vacation
• Ground-floor role with a fast-growing company and a clear path to lead technician

Schedule

• Full-time, overnight / graveyard shift — a mix of field and central-shop work
• Weekend and holiday coverage as needed; our operation runs 24/7, 365 days a year
