About the role

Evaluate the quality, correctness, and methodological rigor of applied machine-learning tasks used to train and evaluate a frontier AI lab's models. You'll assess experiment design, model-selection reasoning, and evaluation methodology - and provide clear, rubric-based written feedback.

Basic Qualifications

  • 3+ years hands-on applied/experimental ML (experiment design, model selection, hyperparameter tuning, evaluation methodology)
  • Strong grasp of data-quality rigor: leakage detection, metric gaming, and train/test/CV hygiene
  • Proficiency with standard ML frameworks (PyTorch, TensorFlow, scikit-learn, XGBoost)
  • Ability to critique ML claims against evidence and reproduce results

Preferred Qualifications

  • Competition / benchmark experience (e.g., Kaggle)
  • Graduate research or publication record in applied ML
  • Prior task-grading or peer-review experience

Note: this role evaluates applied/experimental ML rigor - it is not an LLM-application-building or MLOps role.

This role is 100% remote, for applicants located in United States.
