Job description

The work

You will create high-quality training inputs for AI systems by designing, reviewing, and explaining sophisticated multi-part CAD assemblies. The work focuses on parametric modeling, assembly reasoning, design feasibility, and manufacturability.

You will explain the reasoning behind assembly architectures, component placement, mating strategies, tolerance stack-ups, and design for manufacturability. You will also document modeling practices, trade-offs, and design intent, review sample designs, provide detailed feedback, and contribute mentoring or educational content for other CAD users.

• Interpret product requirements and create robust, manufacturable multi-part assemblies.
• Create, annotate, optimize, and review 3D models using professional parametric CAD methods.
• Explain CAD decisions, assembly intent, modeling strategies, trade-offs, tolerances, and feasibility.
• Communicate clearly in writing and conversation in a remote, asynchronous setting.

What it pays and takes

This is a remote, part-time contractor role. The listing marks the experience level as entry level, while the role itself prefers substantial professional experience with complex multi-part assemblies.

• Pay: $40-$90 per hour.
• Time: 20+ hours per week.
• Work location: Remote, subject to the role's eligible-country list.
• Language: English.
• Experience: Typically five or more years of professional CAD design experience with complex multi-part assemblies is preferred.
• Credentials such as CSWE, CSWP, Autodesk Certified Instructor or Expert Elite, ASME GDTP, or SOLIDWORKS Champion may substitute for the formal experience preference.
• CAD skills: Mastery of a major parametric CAD package such as SolidWorks, Creo, NX, CATIA, Inventor, Fusion, Onshape, or Solid Edge.
• Requirements: Strong attention to detail and the ability to explain design logic, trade-offs, tolerances, mating strategies, manufacturability, and assembly intent.
• Helpful background: Mentoring or teaching CAD users, enabling other CAD users, familiarity with FreeCAD, or prior AI experience. Prior AI experience is not required.
