About the role

Research Scientist Intern to develop scalable offline reinforcement learning methods for post-training vision-language-action models and world action models for robotic manipulation. Twelve to twenty-four week internship with various start dates.

Responsibilities

  • Develop scalable offline RL algorithms for post-training WAMs and VLAs using large, heterogeneous robot datasets.
  • Investigate reward learning, value estimation, and policy optimization for generative action models, including approaches that use learned world models to support policy improvement.
  • Address challenges in learning from mixed-quality experience, including distribution shift, sparse rewards, and long-horizon credit assignment.
  • Build efficient training and data pipelines, and study how policy performance scales with dataset size, model capacity, and compute.
  • Design experiments and benchmarks to evaluate policy improvement and generalization across tasks and environments.
  • Collaborate with research scientists and engineers to evaluate learned policies in simulation and on real robots.
  • Communicate research findings and publish results at leading machine learning and robotics venues.

Qualifications

  • Currently has or is in the process of obtaining a Ph.D. degree in Computer Science, Machine Learning, Artificial Intelligence, Robotics, or a related STEM field
  • Research experience in reinforcement learning, including policy optimization, value learning, or offline/off-policy learning
  • Experience implementing and training deep learning models using Python and PyTorch or a comparable framework
  • Experience designing controlled experiments, analyzing results, and debugging machine learning algorithms
  • Interpersonal experience: cross-group and cross-culture collaboration
  • Must obtain work authorization in country of employment at the time of hire and maintain ongoing work authorization during employment
