Data Science Expert - AI Content Specialist
About this role
About the Role What if your data science knowledge could directly shape the intelligence of tomorrow's AI systems? We're looking for Data Science Experts to stress-test, evaluate, and improve advanced AI models — exposing gaps in their reasoning and helping build more accurate, reliable machine learning capabilities. This is a fully remote, flexible contract role built for experienced data scientists and quantitative researchers 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: Craft complex, domain-rich data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more — specifically engineered to probe the limits of AI reasoning - Author Ground-Truth Solutions: Develop rigorous, step-by-step reference solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as the definitive standard for model evaluation - Audit AI-Generated Code: Review and assess AI outputs across libraries like Scikit-Learn, PyTorch, and TensorFlow — evaluating technical accuracy, efficiency, and correctness of data visualizations and statistical summaries - Refine AI Reasoning: Identify subtle logical failures — data leakage, overfitting, improper handling of imbalanced datasets — and provide structured, actionable feedback that directly improves how models think Who You Are - Holds or is pursuing a Master's or PhD in Data Science, Statistics, Computer Science, or a quantitative discipline with a strong data focus - Deep knowledge across core areas: supervised/unsupervised learning, deep learning, NLP, or big data technologies (Spark, Hadoop) - Able to communicate complex algorithmic and statistical concepts clearly and precisely in writing - Exceptionally detail-oriented — code syntax, mathematical notation, and statistical validity all matter to you - No prior AI or annotation experience required Nice to Have - Experience with data annotation, quality evaluation, or labeling systems - Familiarity with production-level data science workflows — MLOps, CI/CD for models, experiment tracking - Background in academic research or technical writing Why Join Us - Work directly with industry-leading AI language models at the frontier of research - Fully remote and asynchronous — work when and where you perform best - Freelance flexibility with consistent, substantive task-based work - Contribute to AI development that has a real and lasting impact on how models reason about data science - Potential for ongoing work and contract extension as new projects launch
