We are sharing a specialised consulting opportunity for experienced CAD Data Generation & Validation Specialists with strong expertise in FreeCAD, Python, parametric modelling, mechanical design, CAD validation, GD&T, manufacturing processes, and engineering documentation to contribute to an advanced AI training and engineering-data project. Selected professionals will create, edit, validate, and document high-quality parametric CAD models used in AI training datasets, with a strong focus on geometric accuracy, engineering best practices, reproducibility, and manufacturing relevance. The work combines CAD generation, quality assurance, technical documentation, and optional Python-based automation.
Key Responsibilities
- Parametric CAD Model Generation
- Create precise parametric CAD models using FreeCAD
- Develop mechanical parts, assemblies, and reusable geometric features
- Apply robust modelling practices that preserve design intent
- Maintain geometric accuracy across complex model structures
- Build diverse CAD assets suitable for dataset development and AI training
- CAD Validation & Quality Assurance
- Review CAD models for dimensional, geometric, and structural accuracy
- Identify discrepancies, modelling errors, or incomplete design information
- Validate models against engineering requirements and best practices
- Correct issues while preserving intended functionality and parametric behaviour
- Maintain consistent quality standards across large collections of CAD data
- GD&T & Engineering Standards
- Apply Geometric Dimensioning & Tolerancing principles to mechanical models
- Ensure CAD outputs reflect real-world manufacturing standards
- Review dimensional relationships, tolerances, and geometric controls
- Identify design elements that may conflict with manufacturing or inspection requirements
- Apply engineering judgement to maintain realistic and production-relevant model data
- Mechanical & Manufacturing Design
- Apply mechanical-design principles when developing and reviewing components
- Consider common manufacturing methods when evaluating geometry and tolerances
- Incorporate industrial-engineering and manufacturability considerations where relevant
- Ensure models are representative of realistic engineering applications
- Support creation of technically diverse datasets spanning multiple mechanical-design scenarios
- Python & CAD Automation
- Optionally use Python to automate repetitive CAD modelling or validation tasks
- Enhance model parametrisation through scripting where appropriate
- Develop reproducible workflows that improve modelling efficiency
- Support scalable dataset generation through technical automation
- Apply scripting to increase variation, consistency, and richness across CAD assets
- Technical Documentation & Reproducibility
- Document modelling workflows, assumptions, and design decisions clearly
- Maintain detailed engineering documentation for validation and dataset traceability
- Record revisions and quality-assurance findings consistently
- Ensure modelling processes can be reproduced by other technical contributors
- Communicate complex engineering information clearly to both technical and non-technical audiences
Ideal Profile
- 2+ years of experience in mechanical design, CAD modelling, manufacturing, industrial engineering, or a closely related field
- Strong hands-on experience with FreeCAD or equivalent parametric CAD software
- Demonstrated expertise in parametric modelling and mechanical design
- Strong understanding of engineering best practices
- Experience with CAD validation and quality-assurance workflows
- Practical knowledge of GD&T and its application to real-world manufacturing scenarios
- Familiarity with industrial-engineering principles and common manufacturing processes
- Experience preparing detailed engineering documentation
- Strong attention to detail and commitment to geometric accuracy
- Ability to incorporate feedback and revisions efficiently
- Python scripting experience is advantageous, particularly for CAD automation or parametrisation
Engagement Details
- Independent contractor engagement
- Fully remote
- Compensation: $40–$100/hour
- Work will involve FreeCAD modelling, CAD data generation, validation, mechanical-design review, GD&T, quality assurance, and engineering documentation
- Python-based automation may be used to improve modelling efficiency and dataset diversity
- Strong parametric CAD and engineering-quality experience are central to this engagement
- Assignments may include parts, assemblies, features, validation workflows, and manufacturing-oriented CAD scenarios
- 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
