Senior Actuator Engineer, Robotic Hand Systems

Roboticsconnected; Mountain View (WY); On-site; USD 110,000 - 190,000; Full time

Job summary

Rhoda AI is developing the next generation of generalist intelligent robots. We own the full robotics stack from hardware to foundation world models.

You will design actuators at the heart of the hand—compact, efficient motor-gearbox units enabling human-hand dexterity and performance in real-world environments. In this role, you will architect miniaturized geartrains, size motors for torque and efficiency, and collaborate with mechanical and electrical teams to integrate drive and sensing,

Qualifications

• Experience designing and shipping gearboxes, especially planetary gearboxes.
• Experience miniaturizing geartrains for compact packaging.
• Strong motor sizing and efficiency analysis skills.

Responsibilities

• Design compact motor-gearbox actuator units for the hand's fingers and wrist, from concept through production.
• Architect miniaturized geartrains — especially planetary — that hit torque, backlash, and packaging targets at finger scale.
• Size and select motors against torque, speed, power-draw, thermal, and efficiency requirements.
• Build and run bench and dyno tests to characterize actuator performance, efficiency, and durability.
• Partner with the structures engineer on packaging and thermal paths, and with the electrical engineer on drive and sensing integration.
