DESCRIPTION

Partner & General Counsel - Legal Domain Expert Availability & Commitment Confirmation Form (40 hrs/week, Bay Area, California) All application steps are reused whenever another role requires the same step, so you never have to upload your resume or take the same interview twice 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. This is a full-time W-2 employment position with Cincinnatus LLC, with the opportunity to be placed at a leading AI lab as part of their extended workforce. You will be provisioned with client-issued accounts and equipment, and will work inside the client's own tools alongside their research teams. Location: This is a hybrid role based in the Bay Area, California. You must live in the Bay Area and work on-site with the client's team multiple days each week, when required. This is not a remote role. If you do not currently live in the Bay Area, you must be willing to relocate there at your own cost before the engagement starts — relocation assistance is not provided. Key Responsibilities 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. 3. Core
