Mexican Spanish AI QA & Safety Annotator

Mercor; Ciudad de México; Presencial; MXN 120.000 - 180.000; Jornada completa

Descripción de la vacante

Mercor is seeking Mexican Spanish-speaking reviewers to evaluate recorded sessions with a voice-and-camera AI assistant. You will watch each session, compare what the assistant said against what was visible, and score it using a detailed rubric.

Your written comments are the deliverable and you flag failures for fixes. This is judgment work, not volume work, and requires precise, evidence-based commentary.

Formación

• Native or native-level Mexican Spanish, spoken and written.
• Clear, precise written Spanish.
• An Android phone with a working camera and microphone. This is mandatory for the project.
• Attention to detail and the discipline to apply a rubric consistently, without substituting your own criteria along the way.
• Professional English reading comprehension; the scoring guide is written in English.

Responsabilidades

• Review recorded sessions in which a user speaks to an AI assistant while their camera streams whatever is in front of them.
• Compare the assistant's responses against what was actually visible in the video feed, and identify hallucinated or fabricated visual detail.
• Score each session across visual interpretation, accuracy, relevance, response timing, and whether the assistant used spatial and directional language ("to your left", "move your finger up") rather than purely visual description.
• Judge whether the assistant appropriately warned the user when its answer could affect their health, physical safety, or financial security, and whether that warning was timely and proportionate.
• Write detailed open comments that support every score with concrete evidence from the session.
• Capture the conversation turn by turn in the intake form.
