Mechanical Assembly CAD Training Expert

You will help train AI systems by reviewing multi-part mechanical assemblies in FreeCAD-format files and related engineering drawings. The work depends on practical mechanical design knowledge, careful analysis, and clear written feedback.

You will create technical question-and-answer sets that reflect real engineering standards. Questions may cover mechanical functions, design rationale, component relationships, and dimensional considerations.

• Analyze complex mechanical assemblies and interpret their design intent.
• Review component relationships, technical details, and engineering drawings.
• Write precise, objective questions and clear answers.
• Identify and clarify ambiguous technical information.
• Deliver accurate work within agreed project parameters.

What it pays and takes

This is a part-time contractor role for people with strong applied CAD knowledge and real-world experience with mechanical assemblies or engineering drawings. Prior AI training experience is not required.

• Pay: $40 to $80 per hour.
• Work type: Part-time contract work.
• Location: Open to candidates in the countries specified for this role across the Americas, Europe, Africa, Asia, and the Middle East.
• Language: English fluency for technical writing and communication.
• Background: Mechanical engineering, aerospace, or industrial design.
• CAD knowledge: Experience interpreting complex assemblies and engineering drawings.
• Software: FreeCAD familiarity is useful; SolidWorks, CATIA, or Autodesk Inventor experience is also relevant.
• Skills: Strong technical writing, analytical thinking, attention to detail, and objective technical accuracy.
• Work style: Ability to work independently, manage deliverables, and communicate effectively in a remote setting.
