Data Science Expert – AI Content Specialist

About The Role

What if your deep expertise in machine learning and statistics could directly shape how the world's most advanced AI systems think and reason? We're looking for Data Science Experts to stress-test, audit, and train frontier AI models — exposing gaps in their reasoning and building the gold-standard solutions that make them smarter.

This is a fully remote, versátil contract role designed for experienced data scientists, researchers, and quantitative specialists who want to do meaningful, intellectually engaging work on their own terms.

Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week

What You'll Do

Design Advanced Challenges — Create complex, domain-spanning data science problems covering areas like hyperparameter optimization, Bayesian inference, cross-validation strategies, and dimensionality reduction to probe the limits of 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 definitive reference answers
Audit AI-Generated Code — Critically evaluate AI outputs involving libraries like Scikit-Learn, PyTorch, and TensorFlow, assessing for correctness, efficiency, and best practices
Identify and Fix Reasoning Failures — Spot logical flaws in AI reasoning — such as data leakage, overfitting, or improper handling of imbalanced datasets — and provide structured feedback that improves model behavior
Work Independently — Take ownership of your tasks asynchronously, delivering high-quality work on a schedule that suits you

Who You Are

Hold or are pursuing a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
Strong foundational knowledge across core data science areas: supervised/unsupervised learning, deep learning, statistical inference, big data technologies (Spark, Hadoop), or NLP
Able to commun
