hackajob is collaborating with

Mercor to connect them with exceptional professionals for this role.

We're looking for a senior CAD / mechanical design 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, Aerospace Engineering, or Industrial Design (CSWP/CSWE a plus), plus 8+ years of hands-on skilled/industry experience in production design roles — owning designs through GD&T;, tolerance stacks, DFM, and drawing release. Pure analysis/simulation roles with no design-ownership (e.g. only running FEA, never releasing drawings) do not qualify. Candidates from well-known/blue-chip employers preferred.
