AI Computer-Use Trainer (FreeCAD / Mechanical CAD Expert)

You will create realistic FreeCAD tasks and complete them as demonstrations for computer-use AI systems. Your work will show how an expert builds, edits, checks, and delivers parametric CAD models.

You will also create objective evaluation data so submitted computer-use traces can be judged for accuracy, completeness, realism, and model quality.

• Design tasks from dimensioned drawings, spreadsheet-driven parameters, assemblies, TechDraw sheets, manufacturing preparation, and geometry exchange workflows.
• Build parts, sketches, assemblies, drawings, and other FreeCAD deliverables while preserving engineering intent in the model tree.
• Record complete demonstrations and explain reproducible workflows in clear English.
• Define dimensional and structural criteria for successful results.
• Review submitted traces for realistic actions, complete step-to-action mapping, and sound model quality.
• Preserve relevant files before and after each task, keep recordings free of personal information and confidential geometry, and use approved applications.

This is a remote, flexible-hour contractor role. The structured listing describes it as entry level, while the work requires substantial FreeCAD and mechanical CAD skills.

• Pay: $25 to $30 per hour.
• Schedule: Part time, with a requirement of 20 or more hours per week and flexible hours.
• Location: Open to candidates in Bangladesh, Bhutan, Brazil, Cambodia, India, Indonesia, Malaysia, Nepal, Pakistan, Singapore, Sri Lanka, Thailand, the Philippines, Timor-Leste, the United States, and Vietnam.
• Experience: Mechanical design, product development, manufacturing engineering, or a comparable CAD-focused background.
• FreeCAD: Proven skill with Sketcher and Part Design, strong parametric modeling fundamentals, and the ability to troubleshoot constraint-solver failures, broken feature references, and problematic geometry.
• Workbenches: Working knowledge of at least two additional FreeCAD workbenches, such as Assembly, TechDraw, Draft, Spreadsheet, FEM, or CAM/Path.
• File workflows: Familiarity with STEP, IGES, BREP, STL, and mesh workflows.
• Communication: Clear written English at B2 level or higher and consistent use of detailed rubrics.
• Equipment: Ability to run FreeCAD and screen-recording software on Windows 11, Ubuntu X11, or macOS.
