Data Scientist - AI Trainer

DataAnnotation is seeking a Data Scientist - AI Trainer to assess AI-generated quantitative work and craft training tasks that benchmark AI reasoning. This remote role offers flexible scheduling and a platform to influence how AI models approach data and analytics across forecasting, experimental analysis, optimization, and statistical inference.

Responsibilities

• Evaluate AI-produced quantitative work for technical accuracy and real-world validity, covering statistical analysis, predictive modeling, scientific reasoning, and data-driven insights.
• Design and solve quantitative problems used to train and benchmark AI systems, spanning forecasting, experimental analysis, optimization, and statistical inference.
• Write clear technical explanations and maintain well-documented analytical code.
• Provide feedback that directly informs the next generation of AI models built for quantitative reasoning.

Requirements

• 2+ years in a quantitative role or research environment, such as data science, statistics, economics, finance, physics, biology, epidemiology, operations research, or related fields.
• Some coding experience with comfort writing and reviewing analytical code end-to-end.
• Practical experience with statistical methods, predictive modeling, and experiment design (for example, A/B testing, hypothesis testing, regression, classification, time-series forecasting).
• Fluency in English with strong writing skills (native or bilingual level).
• A bachelor's degree in a quantitative field is preferred; a master's or PhD is a plus.
• Relevant credentials are beneficial (e.g., Kaggle competition ranking, AWS or GCP ML certifications, or equivalent demonstrated expertise).

Benefits

• Fully remote: work from anywhere in the US, Canada, UK, Ireland, Australia, and New Zealand.
• Flexible schedule: choose projects and timing that fit your workflow.
• Competitive pay: hourly projects, with the possibility of higher-rate opportunities based on performance.
• Impact: contribute to shaping AI systems designed for quantitative reasoning in data analytics.

Compensation

• Hourly rate: USD 50 - 100 per hour.
