Legal Expert — Disputes & International, Mexico (Project Donna)

Mercor is partnering with a leading legal AI company on a blinded human-preference study. We are hiring **Mexico-based disputes and international arbitration** lawyers to serve as expert reviewers — reading a realistic legal matter, reviewing six AI-generated work products for it, and recording which they prefer with written reasoning.

### What you'll do

• Read a synthetic legal matter and its underlying documents
• Review **six blinded AI deliverables** (labelled A–F) for that matter
• Make **five head-to-head comparisons** against a common comparator output
• Write a short, specific rationale for every preference

### Practice scope
International arbitration and award enforcement, cross-border disputes and emergency interim relief.
### Requirements

• Qualified lawyer with substantive practice experience in the areas above
• Able to judge work product holistically — correctness, completeness, judgment, usefulness
• Precise written English
• Able to work independently to written instructions and a deadline

### Logistics

• **Commitment:** ~24 hours across the engagement.
• **Confidentiality:** all work is synthetically generated. External AI tools must not be used on any project material.
