Mechanical CAD Expert (AI Evaluation)

The work

Use your mechanical design experience to create realistic scenarios and assess AI-generated answers. Your feedback should reflect practical engineering methods and help improve AI performance.

• Create design problems based on real CAD, tolerancing, and manufacturing workflows.
• Evaluate AI responses for technical accuracy, manufacturability, and practical engineering judgment.
• Write structured feedback that explains your assessment clearly.

What it pays and takes

• Pay: Up to $75 per hour.
• Schedule: Flexible, part-time, ongoing project work with no set schedule or minimum hour requirement.
• Location: Open to candidates in the United States. Work remotely and asynchronously.
• The role calls for substantial industry experience in mechanical design and a portfolio of manufactured designs and complex GD&T or FEA work.
• Hands-on mechanical engineering experience and depth in parametric CAD, GD&T and design for manufacturing, or FEA and simulation are required. Candidates who meet at least two of the three core qualifications are encouraged to apply.
• Strong writing, attention to detail, and the ability to explain complex design concepts clearly are required. A BS or MS in Mechanical Engineering is preferred.
• Experience with multiple CAD or simulation tools is helpful, including SolidWorks, CATIA, Fusion 360, or Onshape. A portfolio showing designs from concept through manufacturing can demonstrate practical judgment.

About AI training work

AI training work uses human-created examples and feedback to help improve AI systems, including by reviewing model responses. People with mechanical design expertise can contribute practical judgments that general-purpose examples may not provide.
