About the role

Mechatronics Engineer (Hardware) to design and build actuation, automation, and robotic hardware for autonomous mining vehicles, owning electromechanical and robotics hardware from concept to field validation.

Responsibilities

  • Design and integrate actuation hardware for autonomous mining vehicles — drive-by-wire steering, braking, and throttle, electric and electrohydraulic actuators, and motion and powertrain systems
  • Develop robotic mechanisms and automation hardware (manipulators, end-effectors, automated tooling, and material-handling systems) for unmanned mine operations
  • Produce detailed CAD models, drawings, tolerance stack-ups, and bills of materials ready for fabrication, procurement, and assembly
  • Select, size, and qualify actuators, drives, motors, gearboxes, bearings, and e-powertrain components, balancing build-vs-buy decisions against cost, lead time, and reliability
  • Lead subsystem bench and rig testing, build and instrument prototypes, and drive reliability growth against MTBF and availability targets
  • Collaborate with controls and autonomy-software engineers to integrate actuation, compute, and sensing into a complete vehicle

Qualifications

  • Bachelor's degree in Mechatronics, Mechanical, Robotics, Electrical, or related engineering discipline
  • 5-10+ years designing complex electromechanical or robotic systems, ideally including mobile or heavy equipment
  • Strong proficiency with 3D CAD
  • Hands-on experience with actuation and motion systems - drive-by-wire, electric or electrohydraulic actuators, motors, drives, gearboxes, and their integration
  • Working knowledge of design-for-manufacture/assembly and of component selection, qualification, and supplier engagement
  • Experience in autonomous vehicles, robotics, automotive, or off-highway equipment strongly preferred
