SeniorActuatorModelingEngineer

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 $400M and are investing aggressively in model research, infrastructure, hardware development, and manufacturing scale-up to make generalist robotics a reality. SENIOR ACTUATOR MODELING ENGINEER ABOUT THE ROLE: As a Modeling Engineer, you will develop the mathematical foundation that guides actuator design across our robot fleet. You translate the statistical population of real-world use cases our robots encounter into concrete, defensible design decisions: how big the motor should be, how the gear train should be sized, what to cool, what to optimize, and what each attribute is actually worth. Actuators are the meeting point of electromagnetics, thermodynamics, structural mechanics, and tribology — and the design space is vast. Your models are how we navigate it. The simulations, duty cycles, and sensitivity analyses you build will directly shape what gets prototyped, what gets shipped, and what we choose to leave on the table. We operate as T-shaped engineers. You must be a strong generalist across actuator physics, but your superpower for this role is building rigorous, data-driven models that turn ambiguous customer needs into prioritized, monetized design targets. WHAT YOU'LL DO 1D System Modeling: Develop and maintain the 1D actuator model that serves as the team's source of truth for performance prediction. Keep it correlated to bench and robot data, and evolve it as new physics, components, and use cases emerge. Duty Cycle Development: Synthesize the statistical population of customer use
