Parametric CAD Design and Review Specialist
The work
You will create, revise, and assess three-dimensional mechanical models and technical drawings for an AI training project. The work combines hands-on parametric CAD design with careful explanations of design decisions, model changes, audits, and manufacturing considerations.
- Build fully parametric 3D CAD models of mechanical parts and assemblies from detailed written briefs.
- Edit existing models to meet revised requirements while preserving a strong parametric structure and sound modeling practices.
- Audit models for dimensional accuracy, tolerances, manufacturability, and production readiness.
- Create and interpret technical drawings using ASME Y14.5 or an equivalent geometric dimensioning and tolerancing standard.
- Apply design for manufacturability principles to injection molding, sheet metal, CNC machining, casting, and forging.
- Document the reasoning behind design decisions, model edits, and audit findings for AI training.
- Give precise, practical feedback in written and verbal formats.
What it pays and takes
This is a part-time contractor role marked as entry level in the listing. The requirements call for substantial professional experience, with at least four years of hands-on parametric modeling experience for edit-focused work or 10 or more years for complex creation work.
- Pay: $30 to $100 USD per hour.
- Time: 20+ hours per week.
- Location: Available in the countries listed for this role.
- Language: English.
- Required: Strong Autodesk Inventor expertise and the ability to use comparable parametric CAD platforms.
- Required: Practical GD&T experience with ASME Y14.5 or an equivalent standard.
- Required: Design for manufacturability experience across multiple production processes.
- Required: Ability to manage assembly-level designs and complex mechanical systems.
- Required: Clear technical documentation and stakeholder communication skills.
Helpful experience
Professional experience with FreeCAD, SolidWorks, or Fusion 360 is relevant, and prior professional FreeCAD experience is ideal. Experience rebuilding models from scans or point clouds is also useful.
- FreeCAD, SolidWorks, or Fusion 360 experience.
- Scan-to-CAD or point-cloud-to-model reconstruction.
- Python, iLogic, VBA, NX Open, or similar CAD automation tools.

About AI training work
AI training uses examples prepared and reviewed by people to help artificial intelligence systems improve. Specialists are paid for this work because their professional judgment helps assess technical content that general reviewers may not be able to evaluate.
