Expert AI Trainers in Coding, Finance & Accounting, and Medicine/Nursing

Headquarters: Atlanta, AZ. URL: https://trainbrain.space/ What if the work you already do every day — shipping code, closing books, reading charts — became the training signal that teaches frontier AI how to think in your field? TrainBrain builds expert-authored training data and evaluations for AI labs. We're hiring practising professionals to write, solve, and grade the tasks advanced models are measured against. When a model returns a broken function, a wrong reconciliation, or an unsafe clinical suggestion, it's because no expert caught it during training. You'd be that expert. This isn't your day job in a new wrapper. There are no clients, no month-end close, no tickets, no on-call. You work in writing, on your own schedule, on problems chosen to sit right at the edge of what current models can handle. No AI background required — we train you on the tooling.
