Legal Expert — Tier 1 Specialist (Project Donna)

Mercor is partnering with a leading legal AI company on a blinded human-preference study. This listing covers the scarcest specialisms on the project, where subject-matter depth is hardest to source.

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

One of: sanctions and export controls; structured finance and securitisation; or life sciences and pharmaceutical regulatory. Reviewers are assigned only to matters inside their own specialism.

Requirements

• Qualified lawyer with deep, current practice experience in one of the specialisms 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: ~24–30 hours across the engagement, depending on specialism
• Confidentiality: all work is covered by NDA. External AI tools must not be used on any project material.

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
