RL Researcher

Study how environments, data, and rewards translate into capabilities that generalize.

The role

Turn open questions about agent learning into experiments we can run, reproduce, and learn from. Your work will shape training environments across long-horizon coding, AI4Science, AI4AI, knowledge work, and tool use.

What you’ll work on

  • Design RL experiments to study task difficulty, curricula, reward design, and generalization.
  • Develop verifiers and evaluations that separate useful capability gains from reward exploitation.
  • Investigate long-horizon learning and AI research workflows, including recursive self-improvement.
  • Work with engineers to turn findings into better environments, datasets, and reproducible research.

What you bring

  • Hands-on experience with reinforcement learning, model post-training, or agent evaluation.
  • Strong Python and experience implementing experiments in PyTorch or a similar framework.
  • Sound experimental judgment: clear baselines, controlled comparisons, and careful failure analysis.
  • Ability to explain your results and build research code that others can run and extend.
