CAD Scripting Expert
About the role
Toptal is hiring people who design real mechanical CAD work into Terminal-Bench tasks that an AI agent must solve. Each task needs a scripted CAD solution and automated checks. The posting asks for 3 or more years of hands-on mechanical design. Pay is task-based and the rate is not printed in the description.
What you'll do
- Turn real mechanical CAD work into Terminal-Bench tasks an AI agent must solve end to end.
- Define the files, systems, and environment so the agent can attempt the task.
- Write a scripted reference solution in FreeCAD or CadQuery that rebuilds parts when parameters change.
- Build checks for geometry, dimensions, tolerances, and STEP or IGES outputs.
- Calibrate each task so an expert needs about 60–75 minutes, and revise from reviewer feedback.
Requirements
- 3 or more years designing real mechanical parts that were manufactured or shipped.
- Hands-on CAD within the last 3 years.
- Builds or modifies designs through scripts such as FreeCAD, CadQuery, OpenSCAD, or Onshape FeatureScript.
