Scale AI Human Frontier Collective
The Human Frontier Collective is Scale AI's program for credentialed experts, separate from its Outlier contributor platform. Fellows in medicine, law, finance, STEM, machine learning and software engineering work on frontier AI research and evaluation projects as fully remote 1099 independent contractors, with the US, UK and Canada as separate cohorts: 9 of its 13 fellow postings give an estimated six months, and the machine learning (US, UK, Canada) and US STEM postings say there is no fixed end date (its Greenhouse board, read 5 Nov 2026). It also hires part-time research advisors (finance, legal, medical), creative advisors who bring their craft to Scale's research teams, part-time subject matter experts who audit quality, and, since October 2026, Safety Research Scholars: PhD-level researchers on mentored AI safety projects, 20 hours a week for 3 months.
