Data Science Expert - AI Content Specialist

* Design Expert Challenges — Create advanced data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more — problems that genuinely stress-test AI reasoning * Author Ground-Truth Solutions — Develop rigorous, step-by-step technical solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as the definitive benchmark for AI responses * Audit AI-Generated Code — Evaluate outputs from libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and best practices — catching what others miss * Sharpen AI Reasoning — Identify logical failures in AI outputs — data leakage, overfitting, improper handling of imbalanced datasets — and provide structured feedback that improves how models think * Document Failure Modes — Surface and articulate edge cases and reasoning gaps so AI systems can be hardened against real-world misuse

Who You Are

* Holds or is pursuing a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative discipline * Strong foundational expertise in core data science domains — supervised/unsupervised learning, deep learning, NLP, big data technologies (Spark, Hadoop), or statistical inference * Able to communicate complex algorithmic and statistical concepts clearly and precisely in writing * Exceptionally detail-oriented — you catch errors in code syntax, mathematical notation, and statistical interpretation * Self-directed and comfortable working independently on task-based assignments * No prior AI or annotation experience required — your domain expertise is what matters

Nice to Have

* Experience with data annotation, data quality, or model evaluation systems * Familiarity with production-level data science workflows — MLOps, CI/CD for models, or model monitoring * Prior work reviewing or auditing technical content at scale

Why Join Us

* Work directly with industry-leading large language models on problems that genuinely matter * Fully remote and async — work when and where it suits you * Freelance autonomy with the substance of high-impact, expert-level work * Engage with a global network of top-tier researchers and technical contributors * Potential for ongoing work and contract extension as new projects launch
