Job description

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. OpenTrain AI is recruiting contractors for specialized projects where expert human judgment helps improve how artificial intelligence understands technical information.

• Remote contractor opportunity
• Part-time schedule of 20+ hours per week
• Hourly rate of $40-$80 USD
• Work available in the listed eligible countries

About AI Training Work

AI training is the human side of building modern artificial intelligence. Contributors prepare questions, answers, examples, and evaluations that help AI systems learn accurate concepts and produce more reliable results. In this project, aerospace and CAD expertise will help test whether an AI system can interpret detailed assemblies and technical relationships.

• Apply real-world technical knowledge to cutting-edge AI development
• Create structured examples from authentic design information
• Help improve AI understanding of specialized engineering content

The Role

As an Aerospace CAD Question Authoring Expert, you will review native FreeCAD files and analyze high-fidelity, multi-part aerospace assemblies. You will turn detailed assembly information into objective, non-guessable questions and accurate answers that test technical understanding of design features, functions, and relationships between components.

The role is listed as entry level, but success depends on demonstrated expertise in aerospace, mechanical engineering, or industrial design, along with strong CAD fundamentals and hands-on experience with multi-part assemblies. Prior AI training experience is not required.

• Language: English
• Data focus: document-based question answering and text generation
• Contractor, part-time engagement
• Hourly compensation: $40-$80 USD

What You'll Do

You will work from assembly data to produce clear, well-researched content grounded in the technical evidence available in each design. Your questions should require exact interpretation rather than guesswork, while your answers should be accurate, objective, and comprehensive.

The work also includes communicating through writing and occasional verbal discussions to clarify requirements, maintain technical accuracy, and improve future project workflows.

• Review native FreeCAD files and complex mechanical assemblies
• Author several objective questions for each assembly
• Write accurate answers grounded in assembly data
• Cover important component features, functions, and relationships
• Communicate to clarify requirements and technical details
• Contribute documentation and feedback for future question sets

Requirements

This project requires applied technical knowledge and careful interpretation of complex designs. You should be able to understand design intent, read technical drawings, and express technical conclusions in precise, concise language.

FreeCAD experience or familiarity with a comparable CAD platform is useful but not required. Experience creating educational or documentation content may also support success.

• Expertise in aerospace, mechanical engineering, or industrial design
• Strong understanding of CAD principles
• Hands-on experience with multi-part assemblies
• Ability to interpret design intent and technical drawings
• Ability to write precise, objective questions and evidence-based answers
• Strong written and verbal communication skills
• Exceptional attention to detail
• Familiarity with FreeCAD or a comparable CAD tool is helpful, not required

Why This Work Matters

Every major AI system depends on examples prepared and reviewed by people. By translating complex aerospace CAD assemblies into reliable question-and-answer content, you will contribute specialized knowledge to the rapidly growing field of AI training while working remotely on a flexible contractor project.

• Work at the intersection of engineering expertise and AI development
• Use specialized knowledge without prior AI-training experience
• Build experience in a growing technical field
• Work remotely with a part-time weekly commitment
