## Labeling Overview

**Qualifications / requirements:**
We’re looking for experienced machine learning specialists with expert Python skills who can design and verify computational STEM/ML problems. Ideal contributors have 5+ years of hands-on ML experience, strong statistics/ML foundations, and strong written English (C1+). You should be comfortable writing Python-based solutions and validating results using standard data science libraries.

**What you’ll do:**
You will create original computational STEM/ML problems that reflect real scientific workflows, including problems that require Python programming and non-trivial reasoning to solve. You’ll ensure tasks are computationally intensive (not solvable manually in a reasonable timeframe), verify solutions with Python (e.g., NumPy, Pandas, SciPy, scikit-learn), and clearly document problem statements with correct, validated answers.
