What to Expect
STEM roles are project-based and highly specialized. Depending on your background, you might evaluate a physics simulation's numerical stability, verify a chemistry problem's stoichiometry, check a mathematical proof for logical gaps, or assess whether an AI-generated research summary accurately represents the source literature. Tasks are self-contained and clearly scoped—you'll always know what domain you're working in before accepting a task. Work is intellectually stimulating and compensates for the expertise required. PhD candidates, postdoctoral researchers, and professionals with advanced degrees in STEM fields are the core workforce here. Tasks are available across all major scientific disciplines.

Frequently Asked Questions
Do I need a PhD or Master's degree?
Master's degree strongly preferred; PhD preferred for highest rates ($80-110/hr). Some roles accept Bachelor's degree + 5+ years research experience, but pay will be lower ($50-70/hr).
Which STEM field pays the most?
Physics and mathematics command highest rates ($70-110/hr). Chemistry and biology follow ($60-100/hr). Environmental science typically $50-90/hr. Rare specializations (quantum computing, synthetic biology) may pay premium.
What will I actually evaluate?
AI-generated explanations of scientific concepts, experimental designs, mathematical derivations, and technical reasoning. You'll flag inaccuracies, hallucinations, and misconceptions in AI responses.
Can I work while in a PhD program?
Yes, most platforms allow it. These are contract gigs, not competing employment. Verify your university's policies on outside work, but typically allowed for grad students.
