Job description

Help us find where advanced AI models break in Materials & Chemical Engineering. Create or solve difficult, answerable problems, test model reasoning, and explain precisely why an answer succeeds or fails. Remote project-based work can pay up to $40/hour, depending on the project and demonstrated expertise.

What you'll do:

• Create, solve, or review expert-level problems in areas such as metallurgy, polymers, ceramics, nanomaterials, electrochemistry, chemical processes, and transport phenomena.
• Probe AI-generated answers for subtle factual errors, invalid assumptions, missing cases, and broken reasoning.
• Produce reference answers, derivations, verification notes, or scoring rubrics that another expert can audit.
• Review peer-authored tasks for originality, ambiguity, answerability, and appropriate difficulty.

What we look for:

• Deep academic, research, clinical, teaching, or professional expertise in one or more of: metallurgy, polymers, ceramics, nanomaterials, electrochemistry, chemical processes, and transport phenomena.
• Ability to solve difficult problems independently and explain technical reasoning in clear written English.
• Verifiable evidence such as a publication, thesis, ORCID or institutional profile, patent, specialist practice, teaching record, or competition result.
• Prior AI-evaluation experience is useful but not required; domain depth and careful judgement matter more.
