About the Role
Join a leading AI lab's cutting-edge GenAI team to be at the core of the AI revolution, where your expertise fuels the development of the most advanced AI models. We are hiring a senior legal domain expert to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real legal work. Your legal expertise is the substance of this role. You will review the quality of legal knowledge work tasks, write the instruction specs and golden solutions that define what "correct" looks like, and build the benchmarks that show whether the model is genuinely improving. We are looking for a practising specialist rather than a generalist.
What You'll Do
- Data QA and reviews: Vet the quality of legal knowledge work tasks and model outputs — spotting missing behaviors, thin reasoning, and answers that read well but would not survive professional scrutiny.
- Instruction specs and golden datasets: Write high-quality instruction specs, produce golden solutions to legal problems, and define new legal tasks that reflect how the work is actually done in practice.
- Benchmarks and domain depth: Design challenging legal tasks and evaluation sets, and help build legal-specific skills and tools together with the research team.
- Calibration: Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit legal judgment into explicit, teachable criteria.
You're a Good Fit If You
- 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.
