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.
1\. Overview
We are hiring an experienced counsel-level lawyer to work directly with a leading AI lab's research and program management teams, improving how frontier AI models reason about real legal work.
This listing is for practitioners at counsel or senior associate level, with roughly 8 to 15 years of post-qualification practice. If you are earlier in your career, or if you are at partner or General Counsel level, please apply to the corresponding Legal Domain Expert listing instead — we run separate listings by seniority so the rate matches the experience.
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.
2\. 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.
