Company Description
An Enterprise client is seeking Spanish-speaking coding experts with JSON expertise to support the evaluation and improvement of AI-generated audio responses.
Work is expected to begin right away, and continue for 2-3 months, with the potential for additional work beyond this initial project.

Experts should be comfortable identifying whether outputs are clear, helpful, natural, technically accurate, and aligned with project guidelines.
