ABOUT THE ROLE

Build datasets, evaluation rubrics, and reward signals that help improve large language models. You will work with AI research teams to test data-collection approaches, investigate model failure modes, and develop measurements that inform training runs.

WHAT YOU'LL DO

  • Design data slices that reveal meaningful model failure modes across areas such as finance, software, and enterprise workflows.
  • Build and refine evaluation rubrics and reward signals for RLHF and RLVR pipelines.
  • Model annotator behavior and run experiments to improve model capabilities.
  • Develop quantitative methods to measure dataset quality, diversity, and downstream impact.
  • Create and manage real-world and synthetic data pipelines.
  • Work with research teams to turn training objectives into concrete data and evaluation specifications.

WHAT WE'RE LOOKING FOR

  • One to four years of hands-on experience designing machine learning data-collection strategies and evaluation rubrics.
  • Familiarity with large language model training and evaluation methods.
  • Experience creating data slices to reveal model failure modes across domains such as finance, code, or enterprise workflows.
  • Ability to design lightweight experiments, work through ambiguous results, and draw actionable insights.
  • A practical, builder-oriented approach and interest in how data quality and structure shape model behavior.
