Diesel Mechanic – Heavy Equipment (Field, Home Nightly)

RES Coal LLC
Somerset, PA Full Time
POSTED ON 9/9/2026
AVAILABLE BEFORE 1/6/2027

Heavy Equipment Field Mechanic

RES Coal mines metallurgical coal — the raw material that goes into making steel, not the thermal coal that fuels power plants. Steelmaking still depends on it, and we've grown steadily since 2008, opening new sites while others shut down.

We're hiring Heavy Equipment Field Mechanics to maintain one of the largest CAT mining fleets in Pennsylvania. Steady year-round work, paid drive time, and a take-home service truck — not a road-construction job that stops when the weather turns.

IS THIS YOU?

This role is a fit if you can say yes to most of these:

✓ You've diagnosed and repaired heavy equipment, diesel, or trucks — not just oil changes, greasing, and tires

✓ You can troubleshoot hydraulic and electrical problems without someone walking you through every step

✓ You own hand tools up to 1/2" drive

✓ You can read and work from schematics and service manuals

✓ You can work safely and independently outdoors in a mining environment

✓ You have a CDL-B, or you're willing to get one

Newer to the trade, or stronger on PMs than diagnostics? Look at our Heavy Equipment Lube Technician posting — it's how several of our mechanics got started.

WHY WORK HERE

  • Take-home company service truck — home every night, no overnight travel, paid drive time beyond 30 minutes
  • Backed by a full in-house team: lube techs, parts runners, shop mechanics, rebuild specialists, welders, and line-borers
  • Privately owned and diversified — stable through tough markets, with year-round work
  • Pay moves on skill and performance, not time served — do well and you move up fast
  • Cross-train into weld, rebuild, hydraulics, and electrical if you want to grow

In short — we treat our mechanics like professionals, not numbers on a roster.

POSITION OVERVIEW

Diagnose and repair large mining equipment in the field, including major component changeouts (engines, transmissions, finals). You'll be stationed at one or two primary sites and rotate to others as needed, working closely with lube techs, parts runners, and rebuild teams.

EQUIPMENT FLEET

  • 40 CAT 777 haul trucks (B-series through Next Gen)
  • 29 CAT D11 dozers (N-series through Next Gen)
  • 15 CAT 992 wheel loaders
  • 20 CAT 980 wheel loaders
  • 4 Volvo L220 wheel loaders
  • 5 large production drills
  • 5 excavators in the 45–50 ton class

A TYPICAL DAY

  • Start from home — drive your service truck to the site
  • Continue where you left off, or start a new task based on the foreman's priorities
  • Diagnose electrical, hydraulic, and mechanical issues
  • Order parts and coordinate delivery with the parts runner
  • Check in with the Maintenance Superintendent
  • Drive home — no overnight travel

WHAT SUCCESS LOOKS LIKE

Here's what good looks like to us — and what we promote on:

  • Your repairs hold — minimal comebacks and rework
  • You keep getting better and look for ways to improve how the work gets done
  • You show up on time, every day
  • You fit the crew — you pull your weight and people work well with you
  • You knock out your assigned tasks each day
  • You plan ahead and set yourself up for the next day before you head home

PAY & EARNINGS

What you'll actually earn: $85,800–$130,000 / year

$30–$45 per hour depending on experience, on our standard 50-hour week with overtime after 40 hours. Figure is before bonus. We pay weekly.

  • 50-hour weeks (5–3 or 6–4 schedule); Saturday work available but not required
  • Paid drive time beyond 30 minutes
  • Annual performance bonus on top of base pay

BENEFITS

Coverage starts your first day — not after a 90-day wait. (Short- and long-term disability begin after a short waiting period.)

  • Medical through Highmark Blue Cross Blue Shield or UPMC — choose a high- or low-deductible plan
  • Cover just yourself, you spouse, you kids, or your whole family — premiums run $55–$125 per week
  • Dental and vision insurance
  • Vision plan covers a new pair of prescription safety glasses every year
  • 401(k): 3% safe harbor (we put in 3% even if you contribute nothing) plus a match up to another 3% — up to 6% total from the company
  • Life insurance
  • $100 annual boot allowance
  • Minimum two weeks paid time off
  • Tuition assistance
  • Take-home company service truck, company cell phone, and CAT ET laptop
  • Mechanic-owned tools damaged on the job are replaced in kind

TOOLS & SUPPORT

  • You provide hand tools up to 1/2" drive
  • RES provides large tools, specialty tools, cranes, welders, and diagnostics
  • Company-issued cell phone and CAT ET laptop
  • If a tool improves your efficiency, RES buys it

WHERE THIS LEADS

We promote from within. Many of our technicians started on a lube truck, moved to mechanic helper, and grew into full Field or Shop Technician roles. From there, the path runs toward lead mechanic, rebuild work, and into supervisory roles.

We're also building CAT training opportunities for our maintenance staff to deepen factory-level skills.

NICE TO HAVE

  • Mining or quarry background
  • Hydraulic and electrical troubleshooting experience
  • Experience with CAT ET or similar diagnostic software
  • Welding and fabrication experience
