Mercor is partnering with a leading legal AI company to benchmark how well AI systems answer real questions of Spanish law. We are hiring experienced litigation & disputes lawyers to serve as expert reviewers — running the same prompts through two AI platforms, comparing the answers, and scoring them against a standardized rubric.

What you’ll do

- Run the same set of prompts across two AI (LLM) platforms
- Compare the outputs from both platforms side by side
- Score each response against a standardized rubric we provide
- Submit concise written feedback for every evaluation

Requirements

- Primarily law-firm experience — at least 2 years (3+ preferred) at a law firm in litigation, disputes, or contentious practice. If you are currently in-house, that is fine only if you moved in-house within the last 2 years and your prior experience was at a law firm.
- Qualified to practise in Spain (colegiado/a), with a strong command of Spanish litigation and procedural law
- Native or fluent Spanish, with precise written communication
- Able to work independently to a rubric and to deadlines

Logistics

- Initial commitment: ~10 hours, with strong potential for more
