The work

You will apply mechanical design expertise to AI training work involving engineering drawings, CAD models, manufacturing specifications, and technical documentation. The role focuses on accurate engineering judgment and practical design-for-manufacture decisions.

  • Create and interpret professional engineering drawings with the details needed for manufacturing.
  • Translate complex requirements into accurate, manufacturable CAD specifications.
  • Produce detailed 2D and 3D models using tools such as SolidWorks, Fusion 360, Onshape, Inventor, Creo, and NX.
  • Use FreeCAD to interpret or reference models.
  • Apply drafting standards, dimensioning, tolerancing, and Geometric Dimensioning and Tolerancing principles.
  • Document manufacturing processes and design intent in clear written and verbal formats.
  • Review and improve engineering documentation for clarity and manufacturability.
  • Apply design-for-manufacture knowledge to optimize parts for real production scenarios.
  • Give constructive professional feedback and explain engineering decisions clearly.

Requirements

  • Language: Fluent English for written and verbal communication.
  • Experience: Extensive professional experience in mechanical design, including taking parts from concept through manufacturing.
  • CAD: Expert proficiency across multiple industry-standard CAD platforms, plus hands-on knowledge of FreeCAD for model interpretation or reference.
  • Engineering knowledge: Strong command of drafting standards, GD&T, tolerancing, manufacturing processes, material selection, and design-for-manufacture practices.
  • Communication: Ability to explain engineering decisions, collaborate remotely, and provide constructive professional feedback.
