Mechanical Designer | $80/hr | Remote

FreeCAD, Mechanical CAD & Assembly Design Experts. Remote AI Project
We are seeking experienced FreeCAD specialists, mechanical engineers, CAD designers, aerospace engineers, industrial designers, and assembly modeling experts to create precise, technically rigorous evaluation content based on real multi-part CAD assemblies.
You will inspect CAD models, understand their geometry and mechanical relationships, and create objective question-and-answer sets with exact, verifiable answers.
What You’ll Do
Review complex multi-part mechanical assemblies
Inspect geometry, dimensions, constraints, and component relationships
Understand the functional purpose of parts within an assembly
Create multiple technical questions for each CAD assembly
Ensure questions require genuine engineering or CAD reasoning
Write exact, objective, and independently verifiable answers
Avoid ambiguous, subjective, or guessable questions
Interpret engineering drawings and technical design information
Identify dimensions, clearances, interfaces, orientations, and assembly relationships
Document ambiguities or unusual modeling decisions discovered during review
Incorporate reviewer feedback and refine technical content
Produce clear, assessment-ready engineering material
Collaborate asynchronously with other engineering and project experts
