The role
You will be one of the experts on the front line of our data engine: designing, authoring and reviewing reasoning content that frontier AI labs use to train their best models. This is not labeling. This is advanced LLM reasoning work — constructing multi-step problems, producing reference solutions, and helping us define what “a correct answer” looks like in your domain.
What you will do
· Author original reasoning problems and reference solutions, calibrated to lab-defined difficulty bands.
· Review and rate model responses on rubric criteria; identify failure modes and edge cases.
· Contribute to private benchmarks and Eval-as-a-Service datasets shipped to frontier labs.
· Document your work clearly enough that it can train and evaluate models for years.
Whom are we looking for
· Currently enrolled (or recently graduated) students in one of the four domains above from an accredited university.
· Strong English written communication; clear, unambiguous, structured.
· Comfort working independently against deadlines in a fully remote environment.
· Curiosity about how frontier AI models actually learn — you don’t need ML experience, but you should be excited to develop intuitions on how LLMs work.
Nice to have
· Prior teaching, tutoring, or exam-writing experience.
· Some exposure to LLMs (you’ve prompted models for your work, even informally).
· Multiple-domain expertise (e.g., a physics expert who also codes well).
What we offer
· Fully remote, flexible hours (we coordinate across time zones via async-first workflows).
· Competitive compensation depending on your qualifications.
