About AI Training Work
AI training is the human side of building artificial intelligence. Models learn from examples prepared, reviewed, and explained by people with real-world knowledge. In this project, your mechanical CAD judgment can help evaluate and improve AI-generated design work.
This type of work combines practical engineering with careful review. Contributors may create models, assess technical outputs, document decisions, and provide feedback that helps AI systems handle specialized professional tasks more accurately.
Apply hands-on engineering expertise to cutting-edge AI development
Work remotely with flexible part-time scheduling
Contribute model reviews and technical reasoning for AI training
Build experience and a professional profile in a growing industry
The Role
OpenTrain AI is recruiting a Parametric CAD Design and Review Specialist to support an AI training project. You will create, revise, and assess three-dimensional models and technical drawings while applying expert judgment to design quality, documentation, and manufacturability.
The work combines production-oriented mechanical engineering practice with precise documentation of design decisions, model edits, audits, and manufacturing considerations. You may work on edit-level assignments or complex creation work, depending on your parametric modeling experience.
Develop fully parametric 3D CAD models of mechanical parts and assemblies
Review and revise models against detailed written briefs
Assess design decisions for accuracy, robustness, and production readiness
Support AI training through clear technical explanations and evaluations
What You’ll Do
You will work with parametric CAD models and technical drawings throughout the design and review process. Your documentation should make the reasoning behind changes and findings clear for AI training use, while your feedback should be precise, practical, and solution-oriented.
The role requires attention to both individual parts and assembly-level mechanical systems. You will consider dimensional accuracy, tolerances, design intent, manufacturability, and the modeling practices needed to maintain robust parametric structures.
Create parametric 3D models from detailed written requirements
Edit existing models while preserving robust parametric structure and best practices
Audit models for dimensional accuracy, tolerances, manufacturability, and production readiness
Create and interpret technical drawings using ASME Y14.5 or an equivalent GD&T standard
Apply design-for-manufacturability principles to injection molding, sheet metal, CNC machining, and casting or forging
Document design rationales, model edits, and audit findings for AI training
Communicate precise feedback in written and verbal formats
Requirements
Strong hands-on experience with parametric mechanical CAD modeling is required. Candidates should have at least four years of experience for edit-level work or at least ten years of experience for complex creation work.
You should be comfortable managing assembly-level designs and complex mechanical systems, reviewing models against technical requirements, and explaining your decisions clearly. Strong Autodesk Inventor expertise is required, along with the ability to work with comparable parametric CAD platforms.
At least four years of hands-on parametric modeling experience for edit-level work, or 10+ years for complex creation work
Strong Autodesk Inventor or comparable parametric CAD modeling experience
Assembly-level mechanical design experience
Practical GD&T experience using ASME Y14.5 or an equivalent standard
Ability to review dimensional accuracy and production readiness
Design-for-manufacturability knowledge across multiple manufacturing processes
Clear technical documentation and stakeholder communication skills
Helpful Background
Experience with additional parametric CAD platforms and automation tools can be valuable in this role. Professional FreeCAD experience is especially relevant, while reverse-engineering experience may help with assignments involving reconstruction from captured geometry.
Professional FreeCAD experience
Experience with SolidWorks or Fusion 360
Scan-to-CAD or point-cloud-to-model reconstruction experience
Familiarity with Python, iLogic, VBA, NX Open, or similar CAD automation tools
Who Should Apply
This opportunity is suited to mechanical CAD specialists who enjoy combining detailed modeling with critical review. It may fit professionals with experience in design, engineering documentation, manufacturing readiness, reverse engineering, or CAD automation who want to contribute their expertise to AI development.
The project is open worldwide and requires English-language communication. The engagement is part time at 20 or more hours per week, with contractor status and an hourly pay range of $30 to $100 USD.
