About OpenTrain
OpenTrain is the centralized, open platform where AI training and data-labeling freelancers find work, consolidate opportunities across platforms, and build a unified AI training portfolio they control. We make specialized AI training work easier to track, apply for, and grow into a durable freelance career.

About this role
OpenTrain is recruiting for an AI Data Generalist to analyze, evaluate, and annotate varied datasets that support AI system training and validation. You will help improve model quality by providing clear written feedback, reviewing generated outputs, and applying careful judgment across multiple subject areas. This is a remote contractor engagement with an advertised rate of $50‑$90 per hour; project timing and weekly hours may vary by assignment.

What you will do
You will analyze and annotate a variety of datasets used for AI training and validation, evaluate model outputs for relevance, accuracy, and quality, and refine written input and feedback according to project requirements. The work also involves applying critical thinking to problem-solving tasks across multiple domains, following task guidelines and quality assurance processes, communicating findings clearly in written and verbal formats, and completing detail-oriented work independently and collaboratively.

Required skills
You should have exceptional written and spoken English, strong critical thinking and analytical skills, and the ability to deliver precise, detail-oriented work. Clear written and verbal communication, comfort working independently and collaboratively in a remote setting, and a commitment to completing requirements on time and to a high standard are required.

Helpful background
Previous experience with data labeling or annotation projects is helpful, but prior AI experience is not required. Familiarity with reviewing information for relevance, accuracy, and consistency can support success in this work.

Why work with OpenTrain
OpenTrain gives freelancers one place to manage AI training opportunities instead of rebuilding proof of work on every platform. A stronger OpenTrain profile helps you show credible experience, discover roles that match your skills, and turn AI training and data-labeling work into a long-term portfolio.
