About the Role

Join a small applied research team working directly with frontier AI research labs on challenging post-training problems. This research-first role focuses on reinforcement learning, training data, and experiments that help improve model capabilities.

Responsibilities

  • Design and run post-training loops using reinforcement learning methods such as GRPO, preference optimization, and supervised fine-tuning.
  • Shape and inspect high-fidelity trajectories and training data, with careful attention to correctness and edge cases.
  • Build reward functions, rubrics, validators, and evaluation harnesses that resist reward hacking and measure capability gains.
  • Analyze post-training signals and experiment results across distributed GPU clusters to guide next steps.

Requirements

  • At least 2 years of experience as an applied researcher or research scientist, with hands-on model training experience.
  • Practical reinforcement learning and agent experience beyond standard machine learning engineering work.
