- Verify nutrition information against trusted food-composition references.
- Identify inconsistent, mislabeled, or culturally ambiguous food entries.
- Review AI-generated nutrition content for scientific accuracy, safety, and relevance.
- Help refine guidance for diverse cuisines while maintaining consistency across annotation batches.
Requirements
- At least 3 years of relevant experience in nutrition, dietetics, food science, community nutrition, or a related field.
- Familiarity with food-composition databases and dietary-assessment methods.
- Strong judgment regarding portion estimation, food categorization, and structured nutrition data.
- Comfort using spreadsheets, annotation tools, or structured-data formats.
- Ability to commit for 8 weeks, work 8 hours per day, and overlap at least 4 hours with Pacific Time.
Preferred Qualifications
- RD, RDN, or an equivalent nutrition credential.
- Advanced education in nutrition science, public-health nutrition, or clinical dietetics.
- Experience with multicultural food data or prior AI/ML data labeling.
