We are looking for Senior Counsel — Legal Domain Expert candidates for a project delivered through Mercor.
What you'll do
- 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.
- 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.
- Design challenging legal tasks and evaluation sets, and help build legal-specific skills and tools together with the research team.
- Work with client researchers and specialists in adjacent fields to keep standards consistent, translating tacit legal judgment into explicit, teachable criteria.
What you need
- 8 to 15 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.
- Currently at or has reached counsel, senior associate, senior in-house counsel, or Assistant General Counsel level, with real ownership of matters.
- 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.
- Admission to at least one U.S. state bar, in good standing.
- Able to commit reliably to 40 hours per week for an initial engagement of 6 months.
- 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.
Nice to have
- Juris Doctor (JD) from a highly ranked law school is strongly preferred.
