About the Role
Mercor is partnering with a leading AI lab to measure how well frontier AI models perform real engineering design work. We're hiring experienced CAD, PCB, and 3D design engineers to build realistic, difficult design tasks that expose where AI still falls short. You'll design a realistic engineering problem (a prompt, input files, and a grader that checks the result), run it against frontier models, and refine it until it is fair, realistic, and hard. Realism always comes before difficulty. We're Hiring Across Three Tracks
What You'll Do
- Turn real design work from your field into self-contained tasks: a prompt, input files (STEP, KiCad projects, .blend files, meshes), and an automated grader
- Build and iterate on tasks with an AI coding agent (Claude Code) and version them in Git
- Run each task against frontier models, read the model transcripts, and close leaks and shortcuts until the task is hard for the right reasons
- Pass automated QA and peer review, and document the rationale behind any synthetic data you create
- Attend onboarding and calibration sessions
- You're a Good Fit If You
- Have 3+ years of hands-on design experience in at least one track (industry, research lab, or serious freelance work)
- For the Mechanical CAD track: have hands-on professional experience with SolidWorks, AutoCAD, FreeCAD, or a comparable CAD tool
You're a Good Fit If You
