What the work involves

You open a complex multi-part assembly — provided as native FreeCAD files, not screenshots or STEP exports — and work out what it is, how it goes together, and what the designer intended. From that reading, you author several distinct questions per assembly with exact, verifiable answers: constraint relationships between parts, fastener and fit choices, degrees of freedom, material or tolerance implications, load paths, sequence of assembly. The hard part is not the engineering; it is writing questions that are objective and non-guessable — a question whose answer a model could infer from phrasing alone, or one where two competent engineers would give different answers, is rejected.

Expect to spend real time in the file tree before writing anything. Assemblies are described as advanced, which means many bodies, nested groups, and constraint sets that are not self-explanatory. You will also give feedback to project coordinators as guidelines evolve — early batches often surface ambiguity in the spec itself.

What the platform screens for

  • Genuine mechanical, aerospace, or industrial design background, and the ability to talk through an assembly's design intent under follow-up questioning.
  • Fluency reading multi-part assemblies and technical documentation. FreeCAD specifically is a plus; transferable competence in SolidWorks, Creo, CATIA, NX, Fusion, or Inventor is accepted, but you should be candid about ramp-up time.
  • Prior authoring of structured technical content — documentation, exam items, inspection procedures, training material — is weighted heavily, because the deliverable is written, not modelled.
  • Written precision. Screens tend to ask you to produce or critique a sample question, and vague wording is visible immediately.

Logistics

Fully remote contractor engagement, asynchronous, with per-assembly deliverables rather than fixed shifts. Observed rates for this listing sit between $40 and $80/hr, typically tracking domain seniority and CAD-tool depth; nothing is guaranteed. You will need a machine capable of running FreeCAD on large assemblies comfortably. Work is project-based and volume can vary batch to batch, so it suits people with flexible weekly capacity rather than those needing a guaranteed full load.
