About AI Training Work
AI training is the human work behind modern artificial intelligence. Contributors create demonstrations, review results, and define evaluation standards that help AI systems learn how people use software and complete complex tasks.
In this role, your FreeCAD expertise will help produce high-quality examples and objective assessments for computer-use AI systems.
- Work on cutting-edge computer-use AI development
- Apply real engineering judgment to AI training data
- Work remotely with flexible hours
The Role
OpenTrain AI is recruiting a FreeCAD Computer-Use AI Training Specialist to create expert demonstrations and objective evaluation data for computer-use AI systems. You will design realistic parametric CAD tasks, complete them in FreeCAD, capture action sequences and interface states, preserve relevant files before and after the work, and define repeatable criteria for evaluating results.
- Role type: Part-time contractor
- Experience level: Entry level
- Subject area: Parametric CAD model evaluation
- Advertised pay: Up to $20 per hour
- Time requirement: 20+ hours per week
What You'll Do
You will create realistic CAD tasks and complete them in FreeCAD while preserving engineering intent in the model tree. You will also document reproducible workflows in clear English and evaluate whether demonstrations and submitted traces meet detailed technical standards.
- Create task briefs from dimensioned drawings and spreadsheet-driven parameters
- Build parts, sketches, assemblies, drawings, and other FreeCAD deliverables
- Work with TechDraw sheets, manufacturing preparation, and geometry exchange workflows
- Record complete demonstrations, including the sequence of actions and interface state
- Define dimensional and structural success criteria
- Review traces for realism, completeness, step-to-action mapping, and model quality
- Troubleshoot constraint-solver failures, broken feature references, and problematic geometry
- Keep recordings free of personal information and confidential geometry
- Use approved applications and complete the work using your own expertise
Requirements
This role requires practical mechanical CAD expertise and strong FreeCAD proficiency. You should be able to create robust parametric models, diagnose modeling problems, and explain technical workflows clearly enough for another person to reproduce them.
- Experience in mechanical design, product development, manufacturing engineering, or a comparable CAD-focused role
- Genuine proficiency in FreeCAD Sketcher and Part Design
- Strong parametric modeling fundamentals and robust feature-tree practices
- Experience creating models from dimensioned drawings and spreadsheet-driven parameters
- Ability to diagnose constraint-solver failures, broken feature references, and non-manifold or self-intersecting geometry
- Working knowledge of at least two additional FreeCAD workbenches, such as Assembly, TechDraw, Draft, Spreadsheet, FEM, or CAM/Path
- Familiarity with STEP, IGES, BREP, STL, and mesh workflows
- Ability to apply objective CAD verification rubrics consistently
- Clear written English at B2 level or higher
- Ability to run FreeCAD and screen-recording software on Windows 11, Ubuntu X11, or macOS
