Work on the cutting edge of AI, on your own schedule, and get paid for the data science judgment you already have.

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 analytical problems, judge whether an AI's answer is statistically sound, write the solution a professional would give, and explain clearly where the reasoning breaks down. Your judgment helps shape the next generation of AI models. This is that work, done remotely around your current job.

What you'll do

- Evaluate AI answers to data science and statistics problems, checking whether the methods and conclusions hold up
- Build analytical prompts and datasets to assess quantitative reasoning
- Write the reference answers used to assess model performance
- Give clear feedback on incorrect approaches and statistical mistakes

Why this is worth your time
- Get paid $150–$200 an hour to build real AI skills, on top of your current job
- Work directly with frontier AI tools and see how they are built, tested and improved, experience most people in data science will not have for years
- Build a career edge for what comes next:
