Remote | CAD Data Generation & Validation Specialist (FreeCAD) — $40–$100/hour

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
