Mercor

The company is not a traditional healthcare employer; rather, it engages nursing professionals on a contract basis to contribute domain expertise that advances machine learning systems and AI research. With a $10 billion valuation and backing from investors including Benchmark, General Catalyst, Peter Thiel, Adam D'Angelo, Larry Summers, and Jack Dorsey, Mercor has rapidly grown to approximately 2,217 employees. The company's stated mission is to 'organize human intelligence to power the AI economy.' For nurses, Mercor offers remote contract roles such as Registered Nurse and Personal Health Expert, where professionals create deliverables addressing nursing-domain queries, review peer-developed content, and help diagnose and solve real clinical issues to train AI systems. These roles are short-term (typically 3–4 weeks), require 30–40 hours per week, and demand at least 4 years of professional nursing experience with strong written communication skills. While the prompt lists the location as New York, NY, the company is headquartered in San Francisco and positions are remote. Nursing roles at Mercor represent a non-traditional career path — there is no direct patient care, no clinical facility, and no permanent employment relationship. Instead, nurses function as subject-matter experts feeding their clinical knowledge into AI training pipelines.

Mercor's mission is to 'organize human intelligence to power the AI economy.' The company is built on frontier AI, with every team working directly with frontier models — training them, building around them, and discovering new ways of working. The culture emphasizes independent, asynchronous work and contributing expertise to cutting-edge AI research.
