- Deep understanding of annotation quality frameworks: IAA, consensus labeling, gold standard evaluation, error taxonomy, and calibration workflows
- Direct experience managing labeling platforms (Label Studio strongly preferred, Scale AI, Labelbox, Prodigy, or similar acceptable)

- Familiarity with common ML labeling tasks: text classification, NER, document extraction, intent detection
- Comfortable working in Python and SQL, bonus if you've built tooling around labeling workflows or quality measurement
