  • GitHub repositories or public model implementations
  • Kaggle, DrivenData, AIcrowd, or similar competition results
  • Hugging Face models or datasets
  • Research publications or technical reports
  • Open-source ML contributions
  • Public benchmarks, experiments, or technical projects

Preferred Qualifications

  • Experience creating AI-training tasks, reference answers, rubrics, graders, or benchmark problems.
  • Experience reviewing other AI trainers’ technical submissions.
  • Kaggle Expert, Master, or Grandmaster status, or strong results in another technical competition.
  • Publications or open-source contributions in machine learning.
  • Prior experience with long-horizon or agentic AI evaluations.
  • Availability to begin immediately.

Application Process

  • Submit your application, AI-training experience, and public technical evidence.
  • Complete an AI interview containing technical and integrity checks.
  • Complete a hiring-manager review.
  • If selected, complete project onboarding and begin your first assigned task.
