• Provide structured written feedback to help improve AI model performance
• Complete tasks at your own pace with no set schedule or minimum hour requirement

Qualifications

Ideal candidates meet all three of the following:

• Industry/research experience – minimum 1 year of professional experience at a top company, with direct hands-on work as a data scientist
• Degree – Bachelor's degree in Data Science, Statistics, Mathematics, Computer Science, or a related field
• Sub-domain depth – demonstrated expertise in one of the following areas: Machine learning and applied ML Statistical modeling and experimentation (A/B testing, causal inference) Data analysis and feature engineering at scale

Additional qualifications (not required, but strengthen your application)

• Experience at a recognized, top-tier tech company

Required for all applicants

• Based in the United States
• Strong written communication and attention to detail
• Ability to explain complex data science concepts clearly
