Job description

We're looking for a senior mechanical 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 Mechanical Engineering, plus 8+ years of hands-on professional/industry experience in design, analysis, or R&D. Candidates from well-known/blue-chip employers preferred.
