Data Scientist (Masters) — AI Data Trainer

About The Role

What if your expertise in machine learning, statistical inference, and data engineering could directly shape how the world's most advanced AI systems think and reason? We're looking for data scientists with graduate-level training to stress-test cutting-edge AI models — designing the hardest problems you can imagine, building the gold-standard solutions, and identifying exactly where AI reasoning breaks down.

This is a fully remote, adaptable contract role built for serious data scientists who want to work at the frontier of AI development — on their own schedule.

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

What You'll Do

Design Advanced Challenges — Create rigorous, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
Build Ground-Truth Solutions — Author precise, step-by-step technical solutions including Python/R scripts, SQL queries,



and mathematical derivations that serve as definitive reference answers
Audit AI-Generated Code — Evaluate model outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and technical soundness
Sharpen AI Reasoning — Identify logical failures such as data leakage, overfitting, and improper handling of imbalanced datasets, then provide structured feedback that directly improves how models think
Work Independently — Complete task-based assignments asynchronously, fully on your own schedule

Who You Are

Pursuing or holding a Master's or PhD in Data Science, Statistics, Computer Science, or a quantitative field with solid emphasis on data analysis
Deep foundational knowledge in supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP
Able to communicate complex algorithmic concepts and statistical results clearly and concisely in writing
