Mechanical engineer who creates high-quality technical questions and answers from CAD assemblies for AI model training.
What you would do
- Analyze multi-part CAD assemblies to understand geometry, assembly constraints, and functional design
- Craft several technical questions per assembly requiring application of engineering knowledge
- Develop exact, verifiable answers with clear step-by-step reasoning
- Ensure questions address critical mechanical design concepts and relationships
- Collaborate on feedback and refine deliverables based on requirements
Who they want
- Extensive background in mechanical, aerospace, or industrial design with strong CAD fundamentals
- Significant experience with multi-part assemblies and engineering drawing interpretation
- Knowledge of FreeCAD or similar modeling software; hands-on work with FreeCAD is valued
- Proficiency in communicating complex technical concepts both written and verbally
- Demonstrated ability authoring detailed technical questions or training materials
Main skills
What the interview asks about
1.Assembly constraint interpretation
Understanding how parts connect and move relative to each other is essential for asking meaningful mechanical questions.
For example: “Given a FreeCAD assembly with a sliding joint between two components, how would you verify that a question about motion range reflects the actual design constraints?”
2.Technical question construction
Creating objective, verifiable questions separates training data from ambiguous prompts.
For example: “How would you phrase a question about stress concentration at a fillet radius such that there's one correct answer?”
3.Geometric reasoning
Extracting functional intent from 3D models directly enables you to craft insightful questions.
For example: “A gear assembly uses a particular bore diameter and key slot. What design considerations should your question probe?”
4.Engineering drawing comprehension
Translating 2D drawings into 3D understanding ensures questions test real engineering judgment.
For example: “An engineering drawing shows a tolerance zone notation you haven't seen before. How do you clarify the design intent?”
5.Answer verification rigor
Your answers must be objectively correct and defensible for AI model evaluation.
For example: “You've drafted an answer about load path through a complex assembly. How would you verify it's physically and mechanically sound?”
A task you may get
Analyze a multi-part CAD assembly; identify 3-4 questions that test different aspects of the design (geometry, assembly relations, functional behavior); write verifiable answers with clear reasoning.
How to prepare
- Review recent CAD assemblies you've designed or modified; note key design decisions
- Prepare examples of questions you've asked junior engineers about mechanical design
- Document how you would explain assembly constraints or geometric relationships to a trainee
- Reflect on a complex design problem and how you would frame it as an objective technical question
