CAD Data Generation & Validation Specialist; FreeCAD

Build and validate precise FreeCAD models that help train next-generation AI systems. This remote contract role focuses on producing high-quality, real-world mechanical engineering data that improves how AI models learn, reason, and perform.

• Produce, edit, and validate parametric CAD models in FreeCAD, maintaining geometric accuracy and engineering best practices.
• Create a diverse library of mechanical parts, assemblies, and features for AI dataset development and model training.
• Apply Geometric Dimensioning and Tolerancing principles so models reflect real-world mechanical design standards.
• Review CAD data for quality, identify and resolve discrepancies, and maintain detailed engineering documentation.
• Incorporate feedback and revisions efficiently as project requirements evolve.
• Use Python scripting, when applicable, to automate modeling tasks or improve model parametrization, efficiency, and dataset richness.
• Document modeling workflows and decisions to support reproducible, transparent dataset creation.

• 2+ years of experience in mechanical design, CAD modeling, manufacturing, or industrial engineering.
• Strong experience with FreeCAD or equivalent parametric CAD software.
• Demonstrated expertise in parametric modeling, mechanical design, and engineering best practices.
• Proficiency in CAD validation and applying GD&T in real-world manufacturing scenarios.
• Familiarity with industrial engineering principles and common manufacturing processes.
• Strong attention to detail, precision, and quality assurance.
• Experience preparing comprehensive engineering documentation for technical and non-technical audiences.
