Summary: The Data Scientist (Masters) role involves leveraging advanced knowledge in machine learning and data engineering to develop and evaluate AI models. The position requires designing complex data science challenges, authoring technical solutions, and auditing AI-generated code to enhance AI reasoning. This is a fully remote, flexible contract position that does not require prior AI industry experience but demands strong analytical skills and domain expertise.

Key Responsibilities:

  • Design Advanced Challenges — Create expert-level 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 solutions — including Python/R scripts, SQL queries, and mathematical derivations — that serve as definitive reference answers
  • Audit AI-Generated Code — Evaluate AI outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for technical correctness, efficiency, and best practices
  • Sharpen AI Reasoning — Identify logical failures in AI responses — data leakage, overfitting, improper handling of imbalanced datasets — and provide structured feedback that directly improves model reasoning

Key Skills:

  • Pursuing or holding a Master's or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
  • Strong foundational knowledge across supervised and 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
  • Detail-oriented — you catch errors in code syntax, mathematical notation, and statistical conclusions that others miss
  • Self-motivated and comfortable working independently on an async schedule
  • No prior AI or data annotation experience required
  • Experience with data annotation, data quality systems, or model evaluation (nice to have)
  • Familiarity with production-level data science workflows — MLOps, CI/CD pipelines for models (nice to have)
  • Exposure to multiple programming languages and statistical environments (nice to have)

Detailed Description From Employer:

Data Scientist (Masters) — AI Data Trainer

About The Role

What if your deep knowledge of machine learning, statistical inference, and data engineering could directly shape how the world's most advanced AI thinks and reasons? We're looking for data scientists with advanced training to help build and stress-test cutting-edge AI models. You'll design the kinds of complex, expert-level challenges that push AI systems to their limits — and when they fail, you'll document exactly why, so we can make them better. This is a fully remote, flexible contract role. No prior AI industry experience required — just serious domain expertise and a sharp analytical mind.
