About this job

This role involves designing complex data science challenges and authoring ground-truth solutions to train and evaluate advanced AI models. Data scientists will audit AI-generated code, identify logical reasoning failures, and provide structured feedback to improve model performance across machine learning, statistical inference, and data engineering domains.

What you'll do

  • Design complex data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation, and dimensionality reduction.
  • Develop rigorous technical solutions including Python/R scripts, SQL queries, and mathematical derivations as reference answers for AI training.
  • Evaluate AI model outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and technical soundness.
  • Identify reasoning failures such as data leakage and overfitting, and provide structured feedback to improve model behavior.
