About AI training work

AI training (also called data labeling or human feedback) is the human side of creating intelligent systems: people review, rate, and correct examples so models learn useful behavior. These roles are often remote, flexible, and accessible to language experts and editors, and they directly influence model fluency and cultural accuracy.

The role

We are recruiting a Catalan Quality Assurance Lead to oversee quality, consistency, and trainer performance across Catalan AI training projects.
