PhD Scientist, STEM Expert

Create and evaluate difficult technical problems based on your STEM research area. Each problem should include realistic constraints and supporting data, with a defensible solution and clear reasoning.

• Set objective criteria so another researcher can judge whether an answer is correct.
• Review problems from other contributors for technical accuracy and sound methods.
• Flag problems that are ambiguous, cannot be graded reliably, or are otherwise unsuitable for evaluation.
• Identify plausible but incorrect approaches and explain subtle errors.

• Pay: $45 to $90 per hour.
• Open to candidates in: United Arab Emirates, Argentina, Austria, Bangladesh, Belgium, Bahrain, Brazil, Canada, Switzerland, Chile, Colombia, Germany, Denmark, Algeria, Egypt, Spain, France, United Kingdom, Ghana.

• A completed PhD in a STEM field is required, along with hands-on research experience in wet-lab, academic, industrial, national lab, computational, or theoretical work.
• You must be able to explain and support your technical judgments so another researcher can verify them. Strong judgment about constraints and subtle errors is important.
• Publications or another record of research contribution are an advantage. AI training, model evaluation, or expert data project experience is helpful but not required.
