Data Science Expert – AI Content Specialist About The Role What if your deep knowledge of machine learning, statistics, 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 work alongside leading AI research teams — designing rigorous challenges, authoring gold-standard solutions, and auditing AI-generated outputs to push model performance to its limits. This is a fully remote, adaptable contract role built for experienced 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 Complex Challenges: Craft 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 definitive reference answers

Audit AI-Generated Code: Critically evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow — assessing correctness, efficiency, and best practices

Refine Model Reasoning: Identify logical failures in AI responses — such as data leakage, overfitting,



or improper handling of imbalanced datasets — and provide structured feedback that improves how models think 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 domains: supervised/unsupervised learning, deep learning, big data technologies (Spark/Hadoop), or NLP

Able to communicate complex algorithmic and statistical concepts clearly and precisely in writing

Highly detail-oriented — you catch errors in code syntax, mathematical notation, and statistical reasoning

No prior AI training experience required — your domain expertise is what matters Nice to Have Experience with data annotation, data quality assurance, or AI evaluation workflows

Familiarity with production-level data science practices such as MLOps or CI/CD pipelines for models

Background in technical writing, research, or peer review Why Join Us Work directly on cutting-edge AI projects with world-leading research labs

Fully remote and asynchronous — work when and where it suits you

Freelance autonomy with the structure of meaningful, high-impact technical work

Engage with state-of-the-art language models at a deeper level than almost any other role available

Potential for ongoing work and contract extension as new projects launch
