Senior FreeCAD Engineer

Apply senior-level FreeCAD and mechanical engineering expertise to help train next-generation AI systems through high-quality, real-world engineering input. You will create, assess, and improve CAD deliverables that support how AI models learn, reason, and perform. Prior AI experience is not required.

• Create, modify, and validate detailed parametric CAD models in FreeCAD according to project requirements.
• Develop and optimize mechanical assemblies using sound assembly-design and component-integration practices.
• Apply GD&T and design-for-manufacturing principles to support quality and manufacturability.
• Produce clear technical drawings and documentation for engineering review and downstream processes.
• Conduct engineering quality-assurance reviews of CAD models and drawings, identify issues, communicate findings, and help resolve them.
• Use Python scripting for CAD automation to streamline repetitive or complex modeling tasks, when applicable.
• Provide feedback on model accuracy, design intent, and process improvements.

• 2+ years of experience in mechanical engineering, product design, industrial engineering, or a related field focused on parametric CAD modeling.
• Advanced proficiency with FreeCAD or an equivalent parametric CAD platform.
• Strong mechanical design knowledge, including GD&T and design-for-manufacturing best practices.
• Ability to produce comprehensive technical drawings and documentation for manufacturing and assembly.
• Experience with engineering QA, model-integrity verification, and specification compliance.
• Strong analytical, problem-solving, and communication skills for remote, project-based collaboration.
• Python scripting and CAD automation experience is highly preferred, but not required.
