• Strong working knowledge of hydraulics and diesel systems
• Ability to troubleshoot and repair equipment independently
• Welding experience with steel and aluminum
• Comfort using modern diagnostic tools and computer systems
• Valid Massachusetts driver’s license; ability to obtain a Class A CDL after hire
• Ability to lift 75 to 100 pounds and meet physical demands of the role
• Reliable, detail-oriented, and team-focused
  
  

Preferred But Not Required

• Class A or B CDL
• Experience with Caterpillar or International engines
• Hoisting license or similar equipment certifications
  
  

Benefits

This is a hands-on role for an experienced diesel mechanic who wants steady shop-based work, modern equipment, and the chance to be part of an employee-owned company that values safety, input, and long-term growth.
