Job Purpose
The Autonomous Haulage System (AHS) is a comprehensive fleet management system for mines. Autonomous trucks are centrally controlled through a wireless network that integrates on-board vehicle controllers, high precision global positioning, and obstacle avoidance systems. The AHS Product Development team is responsible for building innovative solutions to unique and challenging autonomous operation problems. Working with our partners around the world, you will help design and support the next generation of mine optimization technologies and build the future platforms that will drive the changes in the mining industry for generations.
