This remote role involves contributing to CritPt, a research-level physics benchmark designed to evaluate advanced AI models on genuine physics reasoning tasks. You'll work on curating, validating, or developing physics problems that go beyond standard textbook exercises, helping assess whether frontier AI systems can tackle authentic research challenges. The work requires deep expertise in mathematical physics and a strong grasp of how AI reasoning differs from rote problem-solving. This position suits PhD-level physicists or researchers comfortable engaging with cutting-edge AI evaluation methodologies. It's offered as flexible remote work at approximately 10 hours per week, at an hourly rate of $80–$110, through the Mercor platform.
