Job Description:

Our DD Labs team builds real-time autonomous delivery systems. The Planning & Decision-Making group is investing heavily in deep reinforcement learning to move beyond classical planning, learning policies that generalize across novel driving scenarios, handle long-tail edge cases, and improve continuously from large-scale fleet data. Our models jointly handle prediction and planning in a single unified architecture. Our stack is pure JAX end-to-end: the same code you train with is the code that runs on the robot. No C++ rewrites, no TensorRT export. A new policy goes from training to on-vehicle deployment in minutes.

Job Responsibility:

  • Formulate complex driving tasks as RL problems with well-shaped reward functions and expressive state/action representations
  • Design and train model-based deep RL agents using GPU-accelerated simulation at massive scale, including improving the simulator itself
  • Build and maintain distributed training infrastructure in JAX across large compute clusters
  • Build agentic optimization systems that automatically improve code, run experiments, analyze metrics, and iterate on RL policies with minimal human intervention

Requirements:

  • BS/MS/PhD in CS, EE, Robotics, or a related field, with a strong foundation in reinforcement learning and deep learning
  • Hands-on experience training RL agents at scale, ideally in robotics, autonomous driving, or other real-time decision-making domains
  • Proficiency in JAX or a similar functional ML framework
  • comfort with JIT compilation, vectorized environments, and GPU-accelerated simulation
  • Deep grasp of core RL concepts: policy gradients, value functions, exploration-exploitation, model-based RL, reward shaping, and sim-to-real transfer
  • Data-driven mindset: comfortable building experiment pipelines, analyzing training runs, and letting metrics guide architectural decisions

Nice to have:

  • Publications at top venues (NeurIPS, ICML, ICLR, CoRL, RSS, ICRA) on RL or learned planning
  • Experience building or working with GPU-accelerated simulators for RL training
  • Track record of shipping a learned component in a production robotics or autonomous vehicle stack
What we offer:
  • 401(k) plan with employer matching
  • 16 weeks of paid parental leave
  • wellness benefits
  • commuter benefits match
  • paid time off
  • paid sick leave
  • medical, dental, and vision benefits
  • 11 paid holidays
  • disability and basic life insurance
  • family-forming assistance
  • mental health program
