Data Science Expert - AI Content Specialist

Data Science Expert – AI Content Specialist
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 Science Experts to stress-test cutting-edge language models, author gold-standard solutions, and help push AI reasoning to its limits.
This is a fully remote, flexible contract role built for serious data scientists who want meaningful, intellectually stimulating work — on their own schedule.
Organization: Alignerr
Type: Hourly Contract
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
Design Advanced Challenges — Create complex, domain-specific data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more
Author Ground-Truth Solutions — Develop rigorous, step-by-step technical responses including Python/R scripts, SQL queries, and mathematical derivations that serve as the definitive "golden" benchmark
Audit AI-Generated Code — Evaluate outputs from models leveraging Scikit-Learn, PyTorch, TensorFlow, and other leading libraries for correctness, efficiency, and best practices
Refine AI Reasoning — Identify and document failure modes such as data leakage, overfitting, and improper handling of imbalanced datasets, then provide structured feedback to improve model logic
Document Model Weaknesses — Systematically probe AI reasoning across machine learning theory, statistical inference, neural network architectures, and data engineering pipelines
Who You Are
Pursuing or holding a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
Strong foundational knowledge across supervised/unsupervised learning, deep learning, big data technologies (Spark, Hadoop), or NLP
Able to communicate complex algorithmic concepts and statistical results clearly and precisely in writing
Highly detail-oriented when reviewing code syntax, mathematical notation, and statistical conclusions
Self-motivated and comfortable working independently on task-based assignments
No prior AI or annotation experience required
Nice to Have
Experience with data annotation, data quality workflows, or AI evaluation systems
Familiarity with production-level data science practices such as MLOps or CI/CD for model deployment
Prior work auditing or benchmarking machine learning pipelines
