Legal Domain Expert — AI Training & Evaluation

3. Core Qualifications

• Education: Juris Doctor (JD) from an accredited law school; a highly ranked school is strongly preferred.
• Experience: 5+ years of substantive post-qualification legal practice at a reputable institution — an established law firm, a corporate legal department, a regulatory body, or a court. Internships and clerkships alone do not count.
• Domain depth: Genuine specialization in at least one substantive practice area, for example corporate and transactional, litigation and dispute resolution, regulatory and compliance, intellectual property, employment and labor, or tax.
• Seniority: Clear progression to a senior level — partner, of counsel, counsel, senior associate, senior in-house counsel, or general counsel — with real ownership of matters.
• Licensure: Active admission to at least one U.S. state bar, in good standing.
• AI fluency: Hands-on working use of large language models in your professional work, and the judgment to tell a well-reasoned answer from a plausible-sounding wrong one.
• Availability: Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
• Location: Living in the Bay Area, California, and able to work on-site with the client's team multiple days each week, when required. Candidates not currently based in the Bay Area must be willing to relocate there at their own cost; relocation assistance is not provided.
• Excellent written communication, and the ability to give precise, well-structured written feedback.
