About The Position

The PhD Scientist — STEM Expert creates challenging technical problems grounded in their own research, including realistic constraints and supporting data. They provide correct solutions with clear reasoning and establish objective criteria that allow other researchers to assess correctness consistently. They also review problems created by other contributors for technical accuracy and sound methodology, and flag problems that are ambiguous or cannot be graded.

This is a contractor role that is fully remote worldwide, with a flexible commitment designed to fit alongside a current role. A completed PhD in a STEM field is required, as is hands-on research experience. Wet-lab, research-lab, or academic experience is strongly preferred. Publications or other evidence of research contributions are a strong plus; prior work on AI training or evaluation projects is helpful but not required.
