Corporate/M&A Lawyer (United Kingdom)

Mercor is partnering with a leading legal AI company to benchmark how well AI systems answer real questions of UK law. We are hiring experienced corporate/M&A 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 corporate/M&A or transactional 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 the United Kingdom, with a strong command of UK corporate and commercial law

• Native or fluent English, with precise written communication

• Able to work independently to a rubric and to deadlines

Logistics

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