Job summary

Analyze complex mechanical assemblies in FreeCAD-format files and identify how their components relate. Develop precise technical questions and accurate answers about mechanical functions, design rationale, and dimensional considerations, then review the work for clarity and engineering accuracy.

Job details

• $40–$80 per hour • 100% remote • Part-time • Fully flexible schedule Work on the cutting edge of AI engineering analysis, on your own schedule, and get paid for the mechanical design expertise you already have. The AI systems everyone is talking about are trained and tested by real engineering experts. The teams building them need mechanical engineers, aerospace engineers and industrial designers who can create realistic questions about assemblies, write the exact answer a professional would give, and check that every question and answer is clear and accurate. Your judgment helps these systems understand how components fit together, why designs work the way they do, and whether technical answers meet real engineering standards. This is that work, done remotely around your current job. What you'll do • Analyze complex, multi-part mechanical assemblies in FreeCAD-format files and identify how the components relate to one another • Create precise technical questions about mechanical functions and design rationale • Write clear answers about dimensional considerations that follow real-world engineering standards • Check technical details, clear up open points with the project team, and deliver accurate work to the project's standards Why this is worth your time • Get paid $40–$80 an hour to build real AI skills, on top of your current job • Work directly with frontier AI tools and see how they are built, tested and improved, experience most mechanical engineers, aerospace engineers and industrial designers will not have for years • Build a career edge for what comes next: AI is reshaping mechanical engineering and industrial design, and the people who understand it from the inside will lead that change • Fully remote, fully flexible, no minimum shift, no commute Who this is for • Strong real-world knowledge of mechanical engineering, aerospace or industrial design • Applied CAD knowledge and experience reading complex assemblies and engineering drawings; FreeCAD familiarity is useful, as is experience with SolidWorks, CATIA or Autodesk Inventor • Fluent English, strong technical writing, analytical thinking and effective remote communication • No AI experience needed. You bring the expertise; we bring the training on the tools. Pay and details • $40–$80 per hour, paid hourly as an independent contractor • Part-time, flexible schedule; fully remote, Canada How to apply 1.
