Mechanical CAD Expert

We are looking for mechanical CAD experts to help train AI systems to understand engineering assemblies. You will analyse multi-part assemblies and write detailed technical questions and answers about function, design rationale and dimensions.

Key Responsibilities
- Study multi-part mechanical assemblies in native CAD files and work out how the components relate and why the design is built that way.
- Write detailed technical questions for each assembly covering function, design rationale and dimensions.
- Check AI answers about assemblies and explain any errors.
- Review and improve geometric representations of assemblies.
- Record your reasoning clearly so that it can be used for training.
- Follow project guidelines, take part in calibration and review sessions, and incorporate feedback to keep quality consistent.

Required Qualifications
- Background in mechanical engineering, aerospace or industrial design with strong applied CAD knowledge.
- Ability to read engineering drawings and interpret complex assemblies.
- Experience with FreeCAD, SolidWorks, CATIA or Inventor.
- Fluent written English.
- Reliable, detail-oriented, and able to work independently and meet deadlines in a remote setting.

Preferred Qualifications
- CSWP or CSWE certification.
- GD&T knowledge.
- Experience in aerospace or manufacturing design.
