16h • $342,000 - $445,000 • Hybrid

About The Position

We are seeking a Senior Actuator Design and Integration Engineer to lead the development of custom electromechanical actuators for advanced robotic systems. You will own actuator development from early architecture and concept generation through prototype validation and system integration, partnering closely with mechanical, electrical, controls, firmware, reliability, and manufacturing teams. This role focuses on the design, integration, and validation of precision electromechanical systems, including motors, transmissions, sensing, structural components, and thermal architectures. You will help drive actuator development across the full engineering lifecycle while establishing scalable design, test, and integration practices for future robotic platforms. This role is based in San Francisco, CA, and requires in-person presence 4 days a week.

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 is a plus.

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.
