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 Research Scientists and Research Engineers to push the frontier of large-scale pre-training for our video action model. Our approach formulates robot control as video prediction — we pre-train causal video generation models on web-scale video data, then adapt them to predict robot actions from real-world demonstrations. You'll work on the core architectures, training objectives, and scaling strategies that determine how well our models learn from internet-scale video. We hire across levels — from senior to staff — and welcome both research-track and engineering-track candidates.
What You'll Do
Design and train large-scale causal video generation models on web-scale video data
Develop and validate training objectives, model architectures, and data mixtures for video prediction at scale
Research scaling laws and data efficiency for web-scale video pretraining
Investigate what properties of web video transfer most effectively to robotic control and action prediction
Build systematic evaluations to measure video generation quality, long-horizon prediction fidelity, and downstream robot task performance
Run rigorous ablations and benchmarking to understand what drives model quality at scale
Collaborate closely with data & evaluation, post-training, and training systems teams to translate research ideas into working systems
Publish and present work at top-tier ML and robotics venues (especially valued for RS track)
What We're Looking For
Strong background in large-scale generative modeling — either video generation (autoregressive video models, diffusion transformers, causal video architectures) or language model pretraining (LLMs, autoregressive transformers at scale)
Hands-on experience training large generative models from scratch at scale
Deep understanding of autoregressive modeling, causal architectures, and scaling behavior
Fluency with modern ML frameworks (PyTorch required; JAX a plus)
Ability to design experiments, interpret results, and iterate quickly
Strong research taste: ability to identify high-leverage questions and cut through noise
Comfort operating in a fast-moving, ambiguous startup environment
Staff-level candidates are expected to define technical direction and drive research strategy independently; senior/MTS candidates execute complex projects with strong fundamentals and growing scope
Nice to Have (But Not Required)
PhD in ML, CS, Robotics, or a related field — or equivalent research/industry experience
Strong publication record at NeurIPS, ICML, ICLR, CVPR, CoRL, etc. (especially valued for RS track)
Prior work specifically on video generation models (autoregressive video, diffusion transformers, world models, or causal video architectures)
Experience with large-scale autoregressive language model pretraining and scaling
Familiarity with web-scale video datasets and video data curation pipelines
Prior work connecting video generation to control, action prediction, or robotic learning
Familiarity with distributed training and multi-node infrastructure
Why This Role
Work on a fundamentally different approach to robot learning — web-scale video pretraining rather than robot-data-only VLA models
Your models give our robots the ability to understand and predict the visual world from internet-scale supervision
Direct collaboration with data, post-training, and deployment teams with no silos
High ownership and fast iteration in a small, elite team
