The work

Create expert evaluation materials that test whether AI models can make sound decisions about materials in professional settings.

  • Write realistic scenarios covering material selection through failure analysis.
  • Provide reference answers and explain the structure-property reasoning behind each decision.
  • Rate model recommendations for technical accuracy, practical feasibility, and suitability for real service conditions.
  • Flag recommendations that sound plausible but would fail in service. Work may draw on metals, polymers, ceramics, or semiconductors.

What it pays and takes

  • Pay: $100 to $130 per hour, paid weekly via Stripe.
  • Hours: At least 10 hours per week; no stated maximum. Work is asynchronous with no fixed schedule, and hours can vary from week to week.
  • Location: Fully remote and open to candidates in eligible countries.
  • Language: English required.
  • Requirements: A degree in materials science and engineering or a closely related field; at least 2 years of professional materials engineering or research and development experience; deep expertise in at least one materials class; and clear technical writing skills.
  • Helpful background: An advanced degree or peer-reviewed publications; experience with SEM, XRD, or DSC; or experience in failure analysis or process qualification.
