A mechanical engineer author technical questions about complex CAD assemblies to train AI reasoning about design structure and function.
What you would do
- Analyze complex multi-part FreeCAD assemblies to understand component relationships and functional purpose
- Create clear, unambiguous technical questions with definitive answers grounded in assembly geometry and function
- Develop multiple unique questions per assembly covering structure, function, and component relationships
- Ensure all questions and answers are unambiguous, precise, and verifiable without original context
- Provide feedback to project coordinators on assembly clarity and question authorship best practices
Who they want
- Professional background spanning mechanical engineering, aerospace, or industrial design with solid CAD skills
- Strong ability to read assembly drawings, technical specs, and CAD models
- Proven track record of authoring technical documentation, assessment materials, or structured content
- Strong written and spoken communication abilities with precision and care for detail
- Experience with FreeCAD or comparable CAD platforms is preferred; FreeCAD expertise is valued
Main skills
What the interview asks about
1.Assembly relationship understanding
If you misidentify how components connect or function together, your questions train the AI to reason incorrectly about mechanical systems.
For example: “You receive an assembly with a spring, damper, and rod connected to a rotating base. Walk through how you determine whether components are load-bearing or regulatory, and how that distinction influences the questions you write about the assembly.”
2.Question precision and exactness
Ambiguous questions train sloppy reasoning; exact answers with no room for interpretation ensure AI learns precise judgment.
For example: “You draft a question: 'How many fasteners connect Component A to the frame?' Later you realize different designers might count subsystems differently. Rewrite this question to be unambiguous with a single correct answer.”
3.Design intent detection
Understanding why an assembly is designed a certain way - not just how it fits together - separates engineering knowledge from mechanical navigation.
For example: “An assembly has wider fastener spacing on one side. Write a question that tests whether the AI understands why spacing differs, not just counts fasteners. What engineering knowledge makes a correct answer valuable?”
4.Documentation sufficiency
Your questions are shared with engineers who never see the original assembly; they must understand your questions without CAD access.
For example: “You write: 'What is the tolerance of the central bore?' An engineer reading this later says 'I do not see tolerance information in your question.' How do you revise the question so it is answerable from the information you provided?”
A task you may get
You receive a 12-part FreeCAD assembly. You author 5-7 technical questions covering structural relationships, functional purpose, and component interactions, with exact answers. Question clarity, diversity of topics, and accuracy of answers are evaluated.
How to prepare
- Refresh your FreeCAD skills: open sample assemblies, manipulate views, and identify key design features
- Practice authoring technical questions where each has a single correct answer with no ambiguity
- Review engineering assessments or interview questions in your domain to understand precision standards
- Prepare examples from your own projects of cases where assembly design choices revealed specific engineering constraints or intentions
