Redefining Robotic Intelligence. Backed by Khosla.
About the role
Own the design of the upper arm end to end — shoulder and elbow joint structures, links, and housings — making the trade-offs between stiffness, mass, inertia, cost, and manufacturability under the highest structural loads in the arm chain Define and own the interface to the torso, including the structural mount, load paths into the frame, alignment and registration features, and the electrical pass-through that feeds the entire arm — driving this interface to closure with the torso team
What they're looking for
- BS in Mechanical Engineering or a closely related field (MS preferred)
- 5+ years of experience in mechanical design of robots, robotic arms, or complex electromechanical products
- Demonstrated ability to make and defend engineering trade-offs — stiffness vs. mass, integration vs. serviceability, performance vs. cost — with quantitative rigor
- Strong experience designing structural components for high-load dynamic systems, including structural analysis correlated to physical test
- Experience defining and driving interfaces with other engineering teams — negotiating requirements and holding designs to them
- Experience integrating high-torque actuators into structural assemblies, including load path design, mounting stiffness, and heat rejection
More about this role
At Rhoda AI, we’re building the next generation of generalist intelligent robots. We own the full robotics stack from high-performance hardware and robot systems to the infrastructure and state-of-the-art foundation world models that control our robots. Our robots are designed to be generalists capable of operating in complex, real-world environments and handling long-tail edge cases, made possible by our cutting edge research and end-to-end system design. We've raised over $450M and are investing aggressively in model research, infrastructure, hardware development, and manufacturing scale-up to make generalist robotics a reality.
We're looking for a Senior Mechanical Engineer to own the upper arm of our humanoid robot platform. The upper arm carries the highest structural loads in the arm chain — it reacts every payload the hand lifts through the shoulder into the torso, houses the largest actuators in the limb, and serves as the trunk through which all power, data, and sensing flow to everything downstream. Working with actuators developed by our dedicated actuation team, you'll own the upper arm end to end: shoulder and elbow joint structures, the interfaces to the torso above...
