About the role
We are building the next generation of intelligent robots. As a leader in Robotics AI Model, you will own the critical pipeline that transforms pretrained foundation models into deployable robot policies — turning general-purpose AI into systems that can reliably manipulate objects, navigate environments, and perform complex physical tasks in the real world.
Key Responsibilities
- Model Post-Training & Fine-Tuning
- Design and execute post-training pipelines for VLA and visuomotor policy models (e.g., diffusion policies, ACT, flow matching), including supervised fine-tuning (SFT), reinforcement learning (RL), and preference-based optimization
- Fine-tune pretrained robot foundation models on task-specific demonstration datasets for dexterous manipulation, locomotion, whole-body control, and multi-step task sequencing
- Develop and iterate on reward functions, verifiers, and RL training loops (PPO, GRPO, RLVR) to improve policy success rate and robustness in simulation and real-world deployment
- Apply parameter-efficient fine-tuning methods (LoRA, QLoRA, OFT) to adapt large models to new tasks and robot embodiments under compute constraints
- Data Pipeline & Curation
- Build and manage large-scale robot demonstration data pipelines: teleoperation data collection, action tokenization (e.g., FAST tokenizer), data augmentation, quality filtering, and dataset versioning
- Define data collection strategies across robot platforms, collaborating with robot operators and data labeling teams to ensure dataset diversity and coverage
- Integrate multi-modal sensory data (RGB, depth, proprioception, force/torque, tactile) into coherent training datasets
- Simulation & Sim-to-Real Transfer
- Build and maintain simulation environments (Isaac Sim, MuJoCo, SAPIEN) for scalable policy training, including domain randomization, asset generation, and task definition
- Address sim-to-real transfer challenges through visual augmentation, action space calibration, dynamics randomization, and systematic real-world validation
- Design and run large-scale distributed RL training across GPU clusters for locomotion and manipulation policies
- Evaluation & Deployment
- Build evaluation and benchmarking infrastructure: automated success-rate tracking, sim evaluation harnesses, real-robot A/B testing, and regression monitoring
- Optimize models for on-robot inference: quantization (INT8/FP8), action chunking, latency reduction, and real-time control loop integration
- Collaborate with controls, perception, and hardware teams to integrate learned policies into the full robot software stack
- Research & Innovation
- Track and adopt state-of-the-art research in robot foundation models, generalist policies, and embodied AI post-training (e.g., π₀/π₀.5, OpenVLA OFT, RT-2, Octo, Helix)
- Contribute to internal research efforts on topics such as multi-embodiment transfer, long-horizon task learning, open-world generalization, and human-in-the-loop policy improvement
Basic Qualifications
- Master’s or PhD in Robotics, Computer Science, Machine Learning, or a closely related field
- 3+ years of hands-on experience in robot learning, including imitation learning, behavior cloning, or visuomotor policy training on real or simulated robots
- Deep expertise in at least one post-training paradigm: SFT on robot demonstrations, RL-based policy optimization, or diffusion/flow-matching policy training
- Strong PyTorch skills with experience training and debugging models at scale; familiarity with distributed training (FSDP, DeepSpeed)
- Practical experience with robot simulation platforms (Isaac Sim, MuJoCo, PyBullet, or SAPIEN) and sim-to-real workflows
- Understanding of action representations for robotics: continuous control, discrete tokenization, action chunking, and diffusion-based action generation
- Solid Python engineering; comfortable working with ROS/ROS2, real-time control systems, and robot hardware integration
- Ability to independently drive projects from research prototype to real-robot deployment
Preferred Qualifications
- Experience fine-tuning VLA models such as π₀, OpenVLA, RT-2, Octo, or similar generalist robot policies
- Hands-on experience with real robot platforms: humanoids, bi-manual arms (ALOHA), mobile manipulators, or dexterous hands
- Experience with large-scale teleoperation data collection systems and robot fleet management
- Familiarity with RLHF/DPO/GRPO applied to robotic policy alignment and human preference learning
- Experience building or contributing to robot learning infrastructure (LeRobot, robomimic, openpi, etc.)
- Publications at top robotics or ML venues (CoRL, RSS, ICRA, NeurIPS, ICML, ICLR)
- Knowledge of on-device model optimization: TensorRT, ONNX Runtime, model pruning, and edge deployment for embodied AI
