Mercor is seeking a senior mechanical engineering expert to craft benchmarks of the toughest reasoning questions in the field, anchored in real industry scenarios. You will author original free-response problems and develop expert solutions grounded in hands-on practice.
In this role you will validate difficulty by comparing three frontier language models, aiming for at least one failure, and you will bring your PhD-level design and R&D experience to bear on challenging tasks.
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.
