Senior/Staff Robot Software Engineer (Simulation)

Senior/Staff Robot Software Engineer (Simulation) LocationMountain ViewEmployment TypeFull timeDepartmentSoftwareAt 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 Robot Software Engineer to build and validate the simulation environments that underpin our humanoid robotics platform. You'll develop physics-based models that closely mirror real hardware, and own the software pipelines that bridge simulation and the physical world — from motion planning and control to sim-to-real transfer for AI policy training. This is a high-impact role on a small team building foundational technology for Gen 0 and Gen 1 robot programs.What You'll DoBuild and maintain simulation environments for our humanoid robot platforms, including physics-based models (e.g., MuJoCo, IsaacSim, PyBullet, or similar) that closely match real hardware behaviorDevelop and validate robot software — including motion planning, control loops, state estimation, and actuator interfaces — in simulation before deployment to physical systemsIntegrate simulation pipelines with the broader software stack: perception, teleoperation, logging, and data collection infrastructureCollaborate with the AI/ML team to build sim-to-real pipelines that accelerate policy training and evaluationWork directly with prototype hardware, debugging discrepancies between simulated and real behavior and iterating on bothContribute to software architecture decisions for our growing robot software platform across multiple robot programsWrite production-quality code that other engineers can build on: clean interfaces, good documentation, and testable componentsWhat We're Looking For4+ years of experience in robotics software engineering or a closely related fieldProficiency with at least one major robotics simulation platform (MuJoCo, IsaacSim, PyBullet, Gazebo, or similar)Strong software engineering fundamentals — production-quality Python and/or C++, clean interfaces, and a commitment to testable, well-documented codeHands-on experience with core robotics software: motion planning, control loops, state estimation, or actuator interfacesExperience integrating software components across a complex stack — connecting simulation to perception, logging, or data collection systemsComfort working directly with physical hardware and debugging sim-to-real discrepanciesStrong communication and collaboration skills — able to work closely with both hardware and AI/ML teammatesNice to Have (But Not Required)Experience building sim-to-real pipelines for reinforcement learning or imitation learning policy trainingFamiliarity with humanoid or legged robot platforms and the unique modeling challenges they presentBackground in whole-body control, trajectory optimization, or model predictive controlExperience with ROS/ROS2 or similar robotics middleware in production or research contextsPrior work on early-stage hardware programs (prototype or pre-production robots)Contributions to open-source robotics simulation tooling or research publications in robotics or robot learningWhy This RoleOwn the simulation layer that bridges AI research and physical hardware — your work directly determines how fast the team can iterate on robot behavior before touching real hardwareWork across the full stack alongside AI/ML researchers, perception engineers, and hardware teams on Gen 0 and Gen 1 programs that define the foundation of the...
