About AI Training Work

AI training is the human side of building modern artificial intelligence. Experts prepare examples, evaluate outputs, and provide structured feedback so AI systems can perform more reliably. In this project, your mechanical design and programming expertise will help create and assess precise CAD examples for AI systems.

• Work remotely from anywhere in the world.
• Choose a flexible workload of less than 20 hours per week.
• Contribute to cutting-edge AI development through specialized technical work.

The Role

OpenTrain is seeking a CAD and Mechanical Design AI Training Expert for a project involving technical drawings, computational geometry, programmatic CAD, and Python. You will interpret dimensioned engineering schematics and reproduce them as accurate 3D solid models using Python and CAD tools.

• Role type: Part-time contractor
• Experience level: Entry level
• Work location: Worldwide and fully remote
• Language: English
• Time requirement: Less than 20 hours per week
• Pay: $50 to $100 USD per hour

What You'll Do

You will transform 2D engineering schematics into precise, verifiable 3D mechanical models. The work combines mechanical design interpretation, computational geometry, CAD automation, and model evaluation.

• Interpret dimensions and geometric relationships from technical drawings.
• Translate 2D schematics into accurate 3D mechanical models.
• Model curved profiles, sweeps, lofts, fillets, chamfers, and Boolean operations.
• Use Python to generate or automate CAD geometry.
• Export valid, watertight solid models in formats such as STEP.
• Validate dimensions, topology, volume, surface area, and inertia properties.
• Troubleshoot and assess CAD models for geometric accuracy.

Required Skills

This role requires strong technical reasoning across Python, 3D CAD, and engineering drawing interpretation. Formal education is not required, but applicants should be able to demonstrate practical ability with precise mechanical geometry and CAD model validation.

• Strong Python programming ability, particularly for CAD automation.
• Hands-on experience with 3D CAD or computational geometry.
• Ability to interpret dimensioned engineering drawings and schematics.
• Strong 3D spatial reasoning and attention to geometric precision.
• Experience validating or troubleshooting CAD models.

Helpful CAD Background

Familiarity with one or more of the following tools is helpful: build123d, CadQuery, FreeCAD, OpenCascade, Fusion 360, Onshape, SolidWorks, or trimesh. Mechanical designers, CAD specialists, engineers, researchers, makers, and independent technical experts are encouraged to apply.

• Programmatic CAD and computational geometry
• Parametric or solid modeling
• Technical drawing and schematic interpretation
• Geometric validation and model troubleshooting
