Remote Materials Writer - Engineering FRQ - AI Trainer ($85-$85 per hour)

We're looking for a senior materials engineering expert to help build a benchmark of the hardest reasoning questions in the field — questions specifically designed to be difficult enough that today's most capable AI models still get them wrong. You'll author original, free-response engineering problems grounded in real industry scenarios, write a complete expert-level solution for each, and validate difficulty by running it against three frontier language models until at least one fails. Requirements: PhD in Materials Science & Engineering, Metallurgy, or a materials-focused Mechanical/Chemical Engineering discipline, plus 5+ years of hands-on professional/industry experience in materials selection, failure analysis, testing, or process development. Candidates from well-known/blue-chip employers preferred.
