About The Position

The selected candidate will support the development, testing, and validation of software-controlled systems used on large mining trucks. This is an excellent opportunity for an engineer who enjoys combining hands-on work with technology, troubleshooting, and machine testing in a real-world operating environment. This role is ideal for someone who wants to work directly with large equipment, electrical systems, controls, and software validation rather than developing software code. You will play a critical role in ensuring production machines perform safely and reliably while helping introduce new technologies and features into future machine platforms.
