You create and refine parametric CAD models of mechanical parts and assemblies while ensuring designs are optimized for real-world manufacturing.
What you would do
- Build fully parametric 3D models from written briefs, emphasizing robust sketching, constraints, and organized feature trees
- Edit existing parametric CAD designs to meet new requirements while preserving design intent and maintaining manufacturability
- Audit and review CAD models for dimensional correctness, proper tolerance application, and practical manufacturing feasibility
- Apply manufacturing expertise to optimize designs across injection molding, sheet metal, CNC machining, and casting processes
- Document and communicate design rationale and feedback with clarity in both written and verbal formats
Who they want
- Extensive hands-on parametric CAD experience, ideally in FreeCAD or strong proficiency in Fusion 360, SolidWorks, or Inventor
- 4+ years hands-on experience with model updates; 10+ years for advanced modeling and design projects
- Proven expertise applying GD&T standards (ASME Y14.5 or equivalent) in actual manufacturing environments
- Strong DFM knowledge spanning multiple manufacturing methods such as molding, sheet metal, CNC, and casting
- Competence with assembly-level modeling, not just single-part design; reverse engineering and scan-to-CAD workflows are valued
Main skills
What the interview asks about
1.Parametric model structure and robustness
Poorly structured parametric models become fragile when updated; robust design ensures AI learns sound modeling practices
For example: “You inherit a Fusion 360 model of an injection-molded bracket where 8 earlier changes broke feature relationships. Describe how you would restructure the feature tree to prevent future cascading failures.”
2.Design-for-manufacturability reasoning
DFM bridges CAD and production; AI learns this relationship through designs that demonstrate manufacturing-aware choices
For example: “A part design specifies a 0.5mm wall thickness for injection molding. Explain why this wall thickness is problematic, what the practical range is, and how you would modify the geometry.”
3.GD&T application and tolerance stack-up
Correct tolerancing prevents assembly and function failures; AI must understand the trade-offs between specification and manufacturability
For example: “Two parts must interface with a 0.01mm clearance to function. Walk through how you would tolerance each part and what stack-up analysis you would perform.”
4.Assembly modeling and relationships
Assembly logic teaches AI how designs function as integrated systems, not isolated parts
For example: “You are modeling a 12-part mechanical assembly with constrained motion. How would you establish the constraint relationships and how would you verify the assembly functions as intended?”
5.Reverse engineering and audit workflows
Auditing real designs teaches AI to recognize deviations from intent and production constraints
For example: “You are given a scan-to-CAD point cloud of a machined part and asked to audit it against the original design model. What dimensional checks and tolerance comparisons would you perform?”
A task you may get
Create a fully parametric CAD model of a mechanical part requiring multiple manufacturing processes (e.g., injection-molded core with CNC-drilled bosses and tapped holes); document the design intent, tolerance stack-up, and manufacturing considerations.
How to prepare
- Review GD&T standards (ASME Y14.5) and document your most complex tolerance application from a real project
- Collect 3-5 examples of your parametric models and explain the feature structure and design logic behind each
- Study a design-for-manufacturability handbook relevant to your primary manufacturing process
- Document a reverse-engineering or model-audit project you completed, including the deviations found and corrections made
