Spain OpenTrain AI is the hiring and contracting organization for this opportunity. OpenTrain is the #1 platform for finding and building careers in AI training and data labeling, helping specialists discover projects, build a professional profile, and apply to work that matches their expertise.
This is a remote, part-time contract opportunity for an experienced legal professional who wants to help shape how advanced AI systems handle real-world legal questions.
AI training is the human side of building artificial intelligence. Experts review and assess model-generated content so AI systems can produce more accurate, useful, and reliable responses.
In this project, your legal judgment will help benchmark language-model performance on questions involving Spanish law, with particular focus on commercial and contract matters.
OpenTrain AI is recruiting a Spanish Law AI Response Evaluation Attorney to compare answers produced by two AI language-model platforms. You will assess the accuracy and quality of responses concerning Spanish legal matters and provide concise, structured feedback explaining each judgment.
The initial commitment is approximately 10 hours, with strong potential for additional work. The engagement is listed as part-time contractor work with a time requirement of 20+ hours per week; confirm the expected schedule before beginning if needed. All project work is covered by a confidentiality agreement.
You will independently review competing AI-generated legal answers and use a standardized evaluation rubric to assess their performance. Your written feedback should be concise, precise, and grounded in your legal expertise.
This role requires substantial professional experience practicing law in Spain. Although the structured listing identifies the opportunity as entry level, the role-specific requirements call for at least five years of in-house legal counsel experience, particularly involving Spanish commercial and contract law.
Experience assessing legal analysis, reviewing contracts or commercial-law materials, or providing structured professional feedback can help you contribute effectively. The work is well suited to an attorney who can combine subject-matter expertise with consistent, rubric-based evaluation.
AI training and data labeling are growing fields that rely on human expertise across writing, evaluation, translation, coding, and specialized professional domains. OpenTrain helps contributors find relevant projects, build a durable portfolio, and grow their careers in this emerging industry.
Creating an OpenTrain account is free, and your profile can help showcase specialized experience as you explore future AI training opportunities.
