Data Scientist (Masters)
AI
Alignerr is seeking Masters-level data scientists to design complex data science challenges, author ground-truth solutions, and audit AI-generated code to improve cutting-edge AI models. This is a fully remote, flexible hourly contract role requiring deep domain knowledge in machine learning, statistical inference, and data engineering, with no prior AI industry experience needed.
What you'll do
- Design Complex Challenges: Craft advanced data science problems spanning hyperparameter optimization, Bayesian inference, cross-validation strategies, dimensionality reduction, and more — specifically designed to stress-test AI reasoning
- Author Ground-Truth Solutions: Build 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 model outputs using libraries like Scikit-Learn, PyTorch, and TensorFlow, assessing them for correctness, efficiency, and technical soundness
