Why Technicians Choose Mobile Auto Mechanics

Mobile Auto Mechanics is one of Long Island’s largest independent providers of on-site commercial truck and equipment services, backed by a full-scale heavy-duty repair shop. Founded in 2010 by brothers Frank and Rob Lecrichia, MAM has grown from one service truck to a high-capacity fleet solutions operation serving major fleets, municipalities, and commercial customers across Long Island. Our expansion has always come from one core formula:
Quality work + strong ethics + unmatched customer trust.

Technicians who join us stay because we offer:

Clean, organized, well-lit bays - that makes your work easier and more professional
Heavy-duty mobile post lifts - capable of lifting dump trucks, tractors, and large commercial equipment
OEM diagnostic laptops provided (Cummins, Ford, Isuzu, etc.)
Paid training and certifications - to grow your skills and advance your career
New Cintas uniforms - Professional, clean, consistent appearance — and we cover it.
A strong, positive, team-first culture - with zero egos and strong communication
A shop leadership team that actually wants you to grow
Respect, stability, and a place you can build a long career

We’re looking for someone who wants long-term stability, takes pride in their work, and thrives in a busy, high-standard commercial truck environment.

What You’ll Be Doing

Your role will combine diagnostics and hands-on mechanical repair.
You’ll be one of our go-to techs for heavy-duty troubleshooting and accurate repairs.

Perform mechanical repairs including:
Truck brakes
Radiators & cooling systems
Suspension & steering
Electrical & aftertreatment
Use OEM & aftermarket diagnostic software
Perform NYS & DOT inspections
Document all work clearly using our shop management system
Support and mentor junior techs when needed
Work closely with a foreman who keeps jobs moving and supports you

What We’re Looking For

These requirements help filter for real heavy-duty experience:

Required

5+ years of heavy-duty diesel truck or commercial equipment experience
Experience with Freightliner, International, Volvo/Mack, Ford, Isuzu, Hino, etc.
Capable of performing both diagnostics and mechanical repairs
Familiarity with aftertreatment systems (DPF, SCR, EGR)
Experience using OEM or high-end diagnostic platforms
Valid driver’s license (CDL A/B preferred but not required)
Must own necessary hand tools for commercial trucks
Ability to thrive in a busy, fast-paced, high-standard shop

Preferred (but not required)

Prior fleet or dealership experience
Any leadership, foreman, or mentor experience

Who Succeeds Here

Technicians who thrive at MAM are:

Dependable & consistent
Detail-oriented and committed to doing the job right
People-oriented team players
Self-motivated problem solvers
Proud of their craft and always improving
Comfortable taking on new challenges

How to Know If This Job Is for You

You’ll be a strong fit if you want:

A shop that’s clean, organized, and built for professional techs
Strong leadership that respects your time and skills
Support from foremen, advisors, and systems — not chaos
Real diagnostic challenges, not entry-level work
A company that matches your ambition

If you're hungry to grow, take pride in your work, and want a great place to build your career — we’d love to talk.
