About the job
Build reinforcement learning environments and evaluation methods so researchers can train models and assess whether progress reflects useful behavior.
What you'll do
- Define and implement environment tasks, observations, actions, state transitions, rewards, and scoring.
- Train and compare baseline agents through controlled experiments; make evaluations reliable and investigate failures.
- Collaborate with domain experts and engineers to develop reusable environments, evaluation tools, and documented methods.
What they ask for
- Hands-on experience formulating RL problems, constructing environments, training agents, and critically assessing results.
- Strong programming and software debugging skills.
- Sound experimental design and statistical reasoning, including evaluation splits and variability.
- Ability to reason about environment dynamics, reward design, and agent behavior, and trace unexpected results to concrete causes.
Nice to have
- Experience building interactive environments, simulators, or benchmarks used by other researchers.
- Work on agent evaluation, reward design, imitation learning, or learning from real-world data.
