[Hiring] CAD Data Generation & Validation Specialist @24-MAG

Role Description

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

Qualifications

• 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
