What You’ll Do

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

Requirements

• Advanced degree: Masters (pursuing or completed) or PhD in Data Science, Statistics, Computer Science, or a quantitative field with a heavy emphasis on data analysis.
• Domain expertise: Strong foundational knowledge in core areas such as supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP.
• Analytical writing: Ability to communicate highly technical algorithmic concepts and statistical results clearly and concisely in written form.
• Attention to detail: High level of precision when checking code syntax, mathematical notation, and the validity of statistical conclusions.
• No AI experience required.

Preferred

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

Why Join Us

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