About AI Training and Legal Model Evaluation

AI training is the human side of building artificial intelligence. Legal experts help improve language models by reviewing AI-generated answers, identifying inaccuracies, and assessing whether responses are complete, well-supported, and professionally reasoned.

This remote contract role gives you the opportunity to apply practical UK legal judgment to the development of cutting-edge AI systems.

The Role

OpenTrain is seeking a UK corporate and M&A legal AI evaluator to assess how accurately AI systems answer real questions of UK law. You will compare responses from two language-model platforms and apply a consistent evaluation rubric.

The role is suited to lawyers who can distinguish legally sound analysis from incomplete, inaccurate, or poorly supported answers and explain their decisions concisely.

• Initial commitment of approximately 10 hours, with strong potential for additional work
• Part-time engagement with a stated time requirement of 20+ hours per week
• Hourly compensation of $150–$160 USD

What You'll Do

You will work independently within a structured model-evaluation workflow. Reviews must be consistent, clearly reasoned, and completed while protecting confidential information under a nondisclosure agreement.

• Run the same legal prompts through two AI language-model platforms
• Compare the resulting answers side by side for legal accuracy and quality
• Score each response against a standardized evaluation rubric
• Submit concise written feedback explaining the basis for each evaluation
• Meet agreed deadlines and protect confidential information under an NDA

• Three or more years of relevant experience preferred
• Strong knowledge of UK corporate and commercial law
• Native or fluent English
• Precise written communication
• Ability to apply a structured rubric consistently
• Sound legal judgment and the ability to compare competing legal analyses
