The AI systems everyone is talking about are trained and tested by real data scientists. The teams building them need data scientists who can create realistic problems and training examples, judge how well the AI handles technical questions, write the answer a professional would give, and explain exactly where its methods or reasoning fall short. Your judgment helps make the next generation of AI models more accurate and reliable. This is that work, done remotely around your current job. What you'll do Assess model responses to problems in statistics, machine learning and data science Write expert prompts and assemble datasets with reference solutions that follow sound technical practice Check each approach and flag statistical errors, weak quantitative reasoning or flawed methods Classify responses as correct, incomplete or unsound, then deliver structured feedback to improve the model Why this is worth your time Get paid $245–$280 an hour to build real AI skills, on top of your current job Judge AI model answers across data science and statistics, covering machine learning, experimentation and quantitative reasoning Find flawed methods and statistical errors, then write reference solutions based on sound technical practice Fully remote and flexible, no fixed shifts, no commute Who this is for Professional work with a leading employer in technology, finance or research must total at least one year; some of that work must fall within the past seven years Strong command of quantitative reasoning and experimentation, along with data science, statistics and machine learning Preferred: an undergraduate degree earned at a top-ranked university, along with clear written and professional communication in English and the ability to work independently You can evaluate AI outputs, identify flawed methods and statistical errors, and write clear reference solutions based on sound technical practice.
