Job Function: Hardware, Embedded & Systems Engineering

Key Responsibilities

  • •Design and integrate actuation hardware for autonomous mining vehicles — drive-by-wire steering, braking, and throttle, electric and electrohydraulic actuators, and the motion and powertrain systems that drive the vehicle
  • •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
