Research Member of Technical Staff- Post-training & Robot Learning

Research Member of Technical Staff- Post-training & Robot Learning LocationMountain ViewEmployment TypeFull timeDepartmentResearchAt 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 Research Scientists and Research Engineers with deep robotics or autonomous systems domain knowledge to adapt our web-pretrained video model to real robot tasks. Post-training at Rhoda means taking a causal video generation model pretrained on internet-scale data and fine-tuning it on robot-collected demonstrations to produce reliable, generalizable behavior — with as little task-specific data as possible. We hire across levels — from senior to staff.What You'll DoDesign and implement RL training pipelines to improve robot policy performance beyond what imitation learning alone achieves — reward design, online data collection, and policy optimizationDevelop and apply RL algorithms (PPO, GRPO, or similar) adapted to the video prediction setting, including reward modeling and feedback collection strategies for physical task performanceDesign and implement broader post-training pipelines: supervised fine-tuning, preference optimization, and behavioral alignment on robot-collected demonstration dataWork on the inverse dynamics model that translates video predictions into executable robot actionsBuild evaluation frameworks for post-trained policies: task success, generalization to novel objects and environments, and failure mode analysis on real hardwareResearch methods to efficiently adapt models to new tasks with minimal demonstration data, including in-context generalization and few-shot adaptationIdentify failure modes and systematic weaknesses in deployed robot policies and drive targeted improvementsIterate quickly between simulation and real robot evaluation to close the feedback loopCollaborate with the pre-training team to surface what capabilities are missing from the base model and need to be addressed upstreamWhat We're Looking ForHands-on experience with robot systems, robotic policy learning, or autonomous systems in an industry or research setting (robotics, self-driving, or similar physical AI domains)Strong understanding of robot policy learning: imitation learning, behavior cloning, and how RL builds on top of itPractical familiarity with real robot hardware, deployment constraints, and sensor modalities (vision, proprioception)Solid ML skills with hands-on PyTorch experienceAbility to diagnose policy failures, reason about distribution shift, and iterate effectively on data and training strategiesComfort with ambiguity and fast-changing research prioritiesStaff-level candidates are expected to define technical direction and drive research strategy independently; senior candidates execute complex projects with strong fundamentals and growing scopeNice to Have (But Not Required)Hands-on experience with reinforcement learning — reward design, policy optimization, and online RL training loops — applied to real or near-real environments (robotics, games, simulated physics, or similar); this is a significant plusPrior industry experience in robotics, autonomous driving, or physical AI (e.g., manipulation, mobile robotics, self-driving stacks)Experience with teleoperation systems or robot demonstration collection at scaleFamiliarity with robot middleware (ROS/ROS2) and real-time control systemsExperience with simulation environments for robotics...
