Data Science Expert - AI Content Specialist

Data Science Expert — AI Content Specialist
About The Role
What if your deep knowledge of machine learning, statistical inference, and data engineering could directly influence how the worlds most advanced AI models reason and respond
Were looking for experienced data scientists to join Alignerrs expert network and help train cutting-edge AI systems. Youll stress-test model reasoning, author gold-standard solutions, and provide the kind of rigorous technical feedback that makes AI genuinely smarter. This is meaningful, intellectually engaging work — done entirely on your terms, from anywhere in the world.

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

What Youll 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 solutions including Python/R scripts, SQL queries, and mathematical derivations that serve as authoritative reference responses
• Audit AI-Generated Code — Evaluate model outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow for correctness, efficiency, and best practices
• Sharpen AI Reasoning — Identify logical failures such as data leakage, overfitting, or improper handling of imbalanced datasets, and provide structured feedback that directly improves how AI models think
  

Who You Are

• Currently pursuing or holding a Masters or PhD in Data Science, Statistics, Computer Science, or a related quantitative field
