About the role

  • Design and implement post-training pipelines for VLA models using techniques such as reinforcement learning (RL), reinforcement learning from human or preference feedback (RLHF/RLAIF), in-context learning.
  • Develop methods to enhance real-world transferability of policies trained in simulation.
  • Explore and implement reset-free and autonomous data collection strategies that enable continual skill improvement without manual resets or supervision.
  • Investigate exploration algorithms that balance safety, curiosity, and efficiency for data gathering in both simulation and real-world robotic systems.
  • Lead the design of data collection and curation pipelines for exploration and post-training.

Requirements

  • Ph.D. or M.S. in Robotics, Machine Learning, Computer Vision, or related field, or equivalent applied research experience.
  • Expertise in reinforcement learning, imitation learning, and multimodal representation learning.
  • Strong proficiency with deep learning frameworks (e.g., PyTorch, JAX) and robotics simulation environments (e.g., MuJoCo, IsaacSim, PyBullet, Habitat).
  • Experience with sim-to-real transfer, policy adaptation, or continual learning in embodied settings.
  • Strong coding and experimental skills with an emphasis on reproducibility and evaluation at scale.
  • Prior robotics experience with real-world hardware and ML-based robot deployments.
Benefits
  • medical, dental, and vision insurance
  • 401(k) eligibility
  • paid time off benefits (including vacation, sick time, and parental leave)
  • annual cash bonus structure
