Bring what you know.

We’re growing a team of experts who turn their knowledge into training tasks and evaluations for AI. If you can work through a hard problem and explain your thinking, we’d like to meet you.

Explain your decisions.
Make your assumptions and reasoning clear enough for someone else to follow and review.
Check the result.
Build a worked solution, a rubric or executable checks. Look for where a convincing answer can still be wrong.

What Expert work looks like.

  • The work

    Write hard problems and reference answers, build grading rubrics and review AI model output in your field. The work is used to train and test AI models, and every task is reviewed for correctness.

  • When you work

    We call Experts in when a project in their field starts. Projects last from 1 month to a year, sometimes longer, with a weekly minimum of about 20 hours of tasks.

  • Between projects

    Some work between projects is paid too, such as training for an upcoming project, and we tell you the pay in writing before you start. Our goal is year-round work for our strongest Experts. It is a goal, not a promise: at first, work can be uneven.

Apply to be an Expert.

Each position covers a whole field. Pick the one closest to your work, or apply for up to 3 in one application.

  1. Pick a position. The field you know best.
  2. Apply in about 20 minutes. Your details, a few questions in your own words, then review and send.
  3. Hear back by email. If you pass the first screen, you take a skills assessment in your field, then a video interview with a founder.

Project-based work, paid per accepted task. Being accepted does not guarantee a project.
