FreeCAD / Mechanical CAD Expert, AI Computer-Use Trainer

About this role

## About SME Careers As AI systems become more sophisticated, they rely on human knowledge to better understand context and the world. At SME Careers, we partner with leading AI labs to improve how the next generation of intelligent systems learn, reason, and act. SME Careers is a fast-growing AI data services company and subsidiary of SuperAnnotate that provides AI training data to many of the world's top AI companies and foundation model labs. Your expertise in parametric CAD will directly help improve the world's premier AI models. ## About the Role AI agents are getting good at reading a screen and clicking through web forms. Put one in front of a parametric CAD package and it falls apart. FreeCAD is an unforgiving test case: multiple workbenches with overlapping capabilities, a constraint solver that fails in ways the interface doesn't explain, feature histories where the correct next action depends entirely on what was built twenty steps earlier, and the topological naming problem lying in wait for anyone who references geometry carelessly. Engineering intent lives in the model tree, not on the screen — and that is exactly what current agents cannot see. In this remote, hourly contract role you will help close that gap. You will design realistic, challenging CAD tasks, then record yourself completing them on your own computer using recording tools we provide. Each recording captures the full picture of how expert work actually gets done, the sequence of actions, the interface state at every step, and the files before and after, and becomes both a demonstration the model learns from and a benchmark it is measured against. Because a model can only learn from work that can be scored, an equally important part of the job is defining what "done correctly" means. Alongside each task you will write the objective and the steps you took, and specify how the result should be verified, what the finished part, sketch, assembly, or drawing has to satisfy for the outco
