We are sharing a specialised consulting opportunity for experienced Autodesk Inventor Specialists with strong expertise in parametric 3D CAD modelling, GD&T, design for manufacturability, assembly-level mechanical design, technical drawing interpretation, reverse engineering, and CAD automation to contribute to an advanced AI training and engineering-data project.
Selected professionals will develop, edit, audit, and document fully parametric mechanical models based on detailed technical requirements, applying professional CAD standards and real-world manufacturing knowledge. Although Autodesk Inventor expertise is especially relevant, the project itself will focus on FreeCAD, making transferable experience across parametric CAD platforms highly valuable. No prior experience in AI is required.
Key Responsibilities
Parametric CAD Modelling
Develop fully parametric 3D CAD models of mechanical parts and assemblies
Build models from detailed written briefs and engineering requirements
Apply robust sketching, dimensional constraints, and feature-tree practices
Ensure models remain editable, stable, and adaptable as requirements change
Maintain clear design intent throughout complex modelling workflows
Model Editing & Assembly-Level Design
Edit and update existing parametric models to reflect revised specifications
Preserve model integrity while incorporating design changes
Work with complex assemblies in addition to individual components
Manage mechanical relationships, constraints, and dependencies across assemblies
Diagnose and resolve fragile features, broken references, and modelling inconsistencies
GD&T & Technical Drawings
Create and interpret detailed technical drawings
Apply GD&T principles consistent with ASME Y14.5 or equivalent standards
Evaluate dimensions, tolerances, datum structures, and geometric controls
Review drawings for consistency with design intent and manufactured geometry
Identify dimensional or tolerance issues requiring correction
Design for Manufacturability
Apply DFM principles across relevant manufacturing processes
Consider injection moulding, sheet metal fabrication, CNC machining, casting, and forging
Identify geometry that may create unnecessary manufacturing complexity or cost
Evaluate whether designs are appropriate for intended production methods
Recommend modifications that improve manufacturability while preserving design intent
CAD Auditing & Quality Assurance
Audit CAD models for dimensional accuracy, tolerance compliance, and manufacturability
Identify gaps, deviations, modelling errors, or incomplete requirements
Review feature structures and assembly relationships for robustness
Document issues clearly and recommend practical corrective actions
Maintain consistent quality standards across model creation and editing tasks
Reverse Engineering & CAD Automation
Support scan-to-CAD and point-cloud-to-model reconstruction workflows
Translate existing geometry into structured parametric models
Apply CAD automation or scripting to improve workflow efficiency
Use tools such as Python, iLogic, VBA, NX Open, or comparable technologies where appropriate
Help standardise repetitive modelling, validation, and documentation processes
Ideal Profile
Minimum of approximately 4 years of hands-on parametric CAD experience for model-editing assignments
Approximately 10+ years of relevant experience may be appropriate for complex model-creation work
Strong expertise in Autodesk Inventor
Experience with FreeCAD, SolidWorks, Fusion 360, or comparable parametric CAD platforms is highly relevant
Prior FreeCAD experience is ideal, as the project itself will focus on FreeCAD
Demonstrated practical experience with GD&T and ASME Y14.5 or equivalent standards
Strong DFM expertise across at least 2–3 manufacturing processes
Experience with injection moulding, sheet metal, CNC machining, casting, forging, or comparable processes
Strong assembly-level modelling skills
Experience with technical drawing interpretation and mechanical design documentation
Reverse-engineering experience involving scan-to-CAD or point-cloud reconstruction is highly valued
Familiarity with CAD automation and scripting using Python, iLogic, VBA, NX Open, or similar tools is advantageous
Strong problem-solving skills and meticulous attention to detail
Excellent written and verbal technical communication
No prior AI-training or model-evaluation experience is required
Engagement Details
Independent contractor engagement
Fully remote
Compensation: $30–$100/hour
Work will involve parametric CAD modelling, model editing, technical drawing interpretation, CAD auditing, GD&T, DFM, assembly design, and engineering documentation
The project will primarily use FreeCAD, while strong Autodesk Inventor and transferable parametric CAD expertise are highly relevant
Assignments may involve mechanical part creation, assembly modelling, reverse engineering, manufacturing review, and CAD automation
Experience requirements may vary depending on task complexity, particularly between model-editing and advanced model-creation assignments
Project scope, workload, modelling requirements, and quality standards may evolve depending on project needs
Work must be completed without using confidential or proprietary information belonging to any employer, client, institution, or other third party
