Hand Actuation Engineer: Planetary Gears for Robotic Hands

Rhoda; Mountain View (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Rhoda AI in Mountain View is seeking a hands-on engineer to design compact motor-gearbox actuators for the hand, delivering dexterity in a human-hand package. You will shape the actuation core of our robotic hand from concept through production, targeting real-world performance.

You will partner with structures and electrical teams to optimize packaging, thermal paths, drive integration and sensing, and you will bench-test actuator performance, efficiency and durability to validate designs.

Qualifications

• Track record of designing and shipping gearboxes, especially planetary gearboxes.
• Experience miniaturizing geartrains for tightly packaged, weight- and volume-constrained applications.
• Strong command of motor sizing and selection, including power draw, torque density, and efficiency analysis.

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 requirementsBuild 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
