  • Experience with PACCAR, Cummins, or Volvo diagnostic platforms and aftertreatment systems such as DPF, SCR, and NOx.
  • Knowledge of CAN J1939 networks, ABS systems, and Eaton transmissions.
  • Ability to read wiring diagrams, interpret fault codes, perform software updates, and program ECMs or other modules.
  • Experience with Fullbay or similar shop management software.
  • Strong troubleshooting skills, attention to detail, reliability, and the ability to work independently and communicate effectively with the team.
  • English language proficiency sufficient for reading technical documentation and communicating with the shop team.

Preferably:

Experience with CAT engine electrical systems, automatic transmission installation and programming, OEM diagnostic tools such as INSITE, ServiceRanger, DAVIE, JPRO, or Jaltest is a plus.

Work schedule and conditions


  • Location: Bear Terminal, Delaware
  • Schedule: Monday–Friday, 8:00 AM–6:00 PM; Saturday, 8:00 AM–1:00 PM
  • Employment Type: 1099 Independent Contractor – Contract Only
  • Work environment: On-site commercial truck maintenance shop, with occasional field assistance when critical fleet situations require it.
  • Physical requirements: Ability to work around heavy vehicles, stand for extended periods, bend, and use diagnostic equipment. Required PPE must be worn.
  • Overtime: May be required to complete critical repairs and maintain fleet readiness.
