About this 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.

What you'll do

Data QA and reviews: Vet the quality of clinical knowledge work tasks and model outputs, spotting missing behaviors, thin reasoning, unsafe or off-guideline recommendations, and answers that read well but would not survive clinical scrutiny.
Instruction specs and golden datasets: Write high-quality instruction specs, produce golden solutions to clinical problems, and define new clinical tasks that reflect how medicine is actually practiced.
Benchmarks and domain depth: Design challenging clinical tasks and evaluation sets, and help build medicine-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 clinical judgment into explicit, teachable criteria.

What you need

Education: MD or DO from an accredited medical school, with a completed residency in a recognized specialty.
Experience: 4+ years of post-residency clinical practice. Residency and fellowship training alone do not count toward the four years.
Licensure: Active, unrestricted license to practice medicine in at least one U.S. state, and board certification in your specialty.
Domain depth: Genuine specialization in a defined clinical specialty, for example internal medicine, oncology, radiology, emergency medicine, surgery, psychiatry, or a medical subspecialty. Experience in utilization management, clinical informatics, or medical affairs is a plus.
Seniority: Clear progression to a senior level, for example Attending Physician, Medical Director, Division Chief, Associate or full Professor, or Chief Medical Officer, with real ownership of clinical decisions.
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.
