About the role

Key responsibilities & impact
  • Define tasks, observations, actions, state transitions, reset behavior, termination conditions, and measurable outcomes for reinforcement learning environments
  • Develop rewards, scoring systems, feedback, and evaluation criteria
  • Test whether agents exploit scoring rules without completing intended tasks
  • Implement baseline agents, train and compare policies, and design controlled learning experiments
  • Separate training and held-out tasks, check for leakage, version experiments, repeat runs, and report uncertainty and performance across conditions
  • Inspect trajectories and learning behavior to identify policy, data, reward, or environment problems
  • Work with domain experts to validate task assumptions
  • Collaborate with engineers to turn research prototypes into reusable environments, evaluation tools, and documented methods

Requirements

What you’ll need
  • Hands-on experience formulating reinforcement learning problems, constructing environments, training agents, and critically assessing results
  • Strong programming and software debugging skills
  • Experience building and testing research systems that others can run and extend
  • Sound experimental design and statistical reasoning, including controlled comparisons, evaluation splits, variability, and benchmark limitations
  • Ability to reason about environment dynamics, reward design, and agent behavior
  • Independent research judgment and clear communication
  • Experience building interactive environments, simulators, or benchmarks used by other researchers (even better)
  • Work on agent evaluation, reward design, imitation learning, or learning from real-world data (even better)
  • Research artifacts with reproducible experiments, useful baselines, and evidence of investigating failures beyond headline scores (even better)

Benefits
