Spanish AI Quality Reviewer

TrustScale is looking for experienced Spanish-language professionals who can distinguish between an acceptable response and an exceptional one.

As an AI Quality Reviewer, you will evaluate AI-generated content, identify quality issues, and help establish the standards that AI systems learn from. This is more than checking boxes or following a script. We are looking for people who can think critically, spot nuances, and make consistent quality decisions.

We are seeking experienced reviewers to support upcoming AI quality initiatives. Applications are reviewed on a rolling basis.
