• Design advanced data science challenges across domains such as hyperparameter optimization, Bayesian inference, cross‑validation strategies, and dimensionality reduction.
• Create rigorous, step‑by‑step technical solutions—including Python/R scripts, SQL queries, and mathematical derivations—that serve as “golden responses.”
• Evaluate AI‑generated code, data visualizations, and statistical summaries for technical accuracy and efficiency using tools like Scikit‑Learn, PyTorch, or TensorFlow.
• Identify logical fallacies in AI reasoning—e.g., data leakage, overfitting, improper handling of imbalanced datasets—and provide structured feedback to improve the model’s reasoning process.

• Advanced degree: Master’s (pursuing or completed) or PhD in Data Science, Statistics, Computer Science, or a related quantitative field.
• Strong foundational knowledge in supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP.
• Excellent analytical writing skills to communicate highly technical algorithmic concepts and statistical results clearly and concisely.
• High level of precision when checking code syntax, mathematical notation, and the validity of statistical conclusions.
• No prior AI experience required.

• Prior experience with data annotation, data quality, or evaluation systems.
• Proficiency in production‑level data science workflows (e.g., MLOps, CI/CD for models).

• Excellent compensation with location‑independent flexibility.
• Direct engagement with industry‑leading LLMs.
• Contractor advantages: high agency, agility, international reach.
• Opportunities for contracting renewals.

• Submit your resume.
• Complete a short screening.
• Project matching and onboarding.
