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 About the Platform This opportunity is available through 24-MAG LLC.
