About The Position

We are sharing a specialised consulting opportunity for experienced Senior FreeCAD Engineers with strong expertise in parametric CAD modelling, mechanical engineering, GD&T, Design for Manufacturing, assembly design, technical drawings, engineering QA, and CAD automation to contribute to an advanced AI training and mechanical-design project. Selected professionals will create, modify, validate, and document detailed parametric CAD models and assemblies, applying professional engineering standards to manufacturability, dimensional accuracy, model integrity, and technical documentation. Python scripting experience is highly valuable for automating repetitive or complex CAD workflows, though it is not mandatory. No prior experience in AI is required.

Requirements

2+ years of experience in mechanical engineering, product design, industrial engineering, or a closely related field
Strong focus on parametric CAD modelling
Advanced proficiency in FreeCAD or comparable parametric CAD platforms
Strong understanding of mechanical-design fundamentals
Practical knowledge of GD&T and Design for Manufacturing principles
Experience creating production-oriented technical drawings and engineering documentation
Strong assembly-design and component-integration skills
Experience conducting engineering QA and validating CAD models against specifications
Strong analytical and problem-solving skills
Excellent written and verbal technical communication
Comfortable contributing independently within a remote, project-based environment
No prior AI-training or model-evaluation experience is required
