  • Coordinate with engineers and writers to confirm parts, steps, and safety details
  • Build icon sets, labels, and callouts that stay consistent across documents
  • Create 2D and 3D illustrations for print, web, and in-product help
  • Review drafts with stakeholders and update visuals after design changes
  • Manage file versions, naming, and exports to meet documentation standards
