About AI Training Work

AI training is the human side of building artificial intelligence. Contributors use professional knowledge to prepare examples, write questions and answers, review technical content, and provide structured feedback so AI systems can learn from accurate, real-world expertise.

This project applies that work to mechanical CAD. Your engineering judgment and careful written explanations will help create high-quality training material based on assemblies, drawings, design intent, and dimensional considerations.

• Contribute to cutting-edge AI development
• Apply specialized professional knowledge to structured training data
• Work remotely with flexible project-based scheduling

The Role

OpenTrain is seeking a Mechanical Assembly CAD AI Training Expert to support Mechanical CAD Assembly Review. You will work with native FreeCAD mechanical assemblies and engineering drawings, using your understanding of complex systems to produce objective, technically accurate question-and-answer sets.

Prior AI training experience is not required. The most important qualification is strong real-world knowledge of mechanical engineering, aerospace, industrial design, or a closely related CAD-focused field.

• Role type: Part-time contractor
• Experience level: Entry level for AI training work
• Time requirement: 20+ hours per week
• Subject area: Mechanical CAD Assembly Review
• Data work: Question answering and text generation

What You'll Do

You will analyze multi-part mechanical assemblies in native FreeCAD files and interpret how their components relate to one another. Your work will connect assembly structure with design intent, mechanical function, and practical engineering considerations.

You will also create clear technical questions and precise answers that reflect real-world engineering standards. Careful review, objective judgment, and clear communication are essential when identifying ambiguities or explaining dimensional and functional details.

• Analyze multi-part mechanical assemblies in native FreeCAD files
• Interpret component relationships and assembly design intent
• Create precise, objective technical question-and-answer sets
• Develop questions about mechanical functions and design rationale
• Address dimensional considerations using accurate engineering reasoning
• Format clear answers aligned with real-world engineering standards
• Review technical details and clarify ambiguities through clear communication
• Deliver accurate work within agreed project parameters

Requirements

Candidates should bring a background in mechanical engineering, aerospace, or industrial design, together with strong applied CAD knowledge. You should be comfortable interpreting complex assemblies and engineering drawings and translating that understanding into accurate written responses.

FreeCAD familiarity is useful. Experience with SolidWorks, CATIA, or Autodesk Inventor is also relevant. Strong technical writing, analytical thinking, dimensional reasoning, and attention to detail are required.

• Background in mechanical engineering, aerospace, or industrial design
• Ability to interpret complex mechanical assemblies and engineering drawings
• Hands-on CAD experience, especially with FreeCAD, SolidWorks, CATIA, or Autodesk Inventor
• Ability to create objective technical questions and precise engineering answers
• Strong technical writing and dimensional reasoning
• High attention to detail and commitment to objective technical accuracy
• Ability to work independently and manage deliverables
• Effective communication in a remote setting

Who Should Apply

This opportunity is a strong fit for a CAD-literate mechanical professional who enjoys examining how assemblies work and explaining technical decisions clearly. It may suit someone entering AI training for the first time, provided they can demonstrate the required engineering and design expertise.

If you are analytical, precise, and comfortable turning complex CAD information into structured technical content, your knowledge can directly support the development of more capable AI systems.

• Mechanical engineers with practical CAD experience
• Aerospace professionals familiar with assemblies and engineering drawings
• Industrial designers who can reason about mechanical structure and function
• CAD specialists with strong technical writing skills
• Experts seeking flexible, remote AI training work
