About the role

Responsibilities

  • Lead the architecture, design, and integration of custom robotic actuators, including motors, transmissions, sensing, thermal systems, structural components, and packaging.
  • Define actuator requirements and system-level trade studies around torque density, bandwidth, efficiency, thermal performance, backdrivability, inertia, reliability, manufacturability, and cost.
  • Design precision electromechanical assemblies with strong attention to tolerances, alignment, load paths, thermal expansion, sealing, wear, and serviceability.
  • Drive actuator integration into robotic systems, partnering closely with controls, firmware, electrical, and robotics software teams to optimize closed-loop performance.
  • Develop and evaluate architectures with integrated sensing and encoder strategies.
  • Build and validate prototypes through hands-on bring-up, debugging, characterization, and iterative refinement.
  • Develop test methodologies and characterization infrastructure for actuator performance, reliability, durability, and failure analysis.
  • Analyze test data to identify limitations, failure modes, and opportunities for design improvement.
  • Collaborate with manufacturing and supplier partners to transition designs from prototype to scalable production-ready assemblies.
  • Support DFM, DFA, DFT, calibration, and assembly strategies for electromechanical subsystems.
  • Contribute to actuator sourcing strategy, vendor qualification, prototype builds, and supply-chain development.
  • Document designs, interfaces, validation results, and engineering decisions to support long-term maintainability and production readiness.
  • Help establish engineering standards, integration practices, and development workflows for future robotic platforms.

Requirements

  • Bachelor’s degree in Mechanical Engineering, Robotics, Mechatronics, or a related field.
  • 7+ years of experience designing electromechanical systems, robotic actuators, or precision mechatronic hardware.
  • Experience developing actuators for robotics, automation, aerospace, automotive, or other high-performance dynamic systems.
  • Strong understanding of motors, transmissions, bearings, encoders, structural design, thermal management, and precision mechanical integration.
  • Familiarity with actuator sensing architectures, including encoder integration and calibration strategies.
  • Experience designing for prototype and production manufacturing processes including machining, casting, molding, and assembly.
  • Proficiency with CAD and PLM tools such as NX and Teamcenter or equivalent systems.
  • Experience developing validation plans, reliability testing, and failure analysis workflows.

Nice-to-Haves

  • Experience scaling hardware systems from prototype through EVT/DVT/PVT and into production.
