Pentangle Tech Services | P5 Group · Decatur, Illinois
Test Engineer to support second-shift testing and validation activities for large mining and construction equipment. This role serves as the primary overnight technical resource responsible for monitoring test systems, investigating failures, diagnosing root causes, and providing troubleshooting guidance to production and maintenance teams.
Unlike a traditional mechanic role, this position focuses on technical problem-solving, system diagnostics, and independent troubleshooting rather than routine repairs. The successful candidate will leverage mechanical, electrical, hydraulic, and electronic diagnostic experience to evaluate failed tests, identify likely causes, and help drive resolution of issues impacting product quality and performance.
This position supports some of Caterpillar's largest wheeled machines, including mining trucks, wheel loaders, motor graders, and scrapers.
