About the role

Key responsibilities & impact

Create and revise CAD models and mechanical drawings for QGG parts, tooling, fixtures, brackets, covers, adapters, and low-complexity assemblies.
Support opto-mechanical, structural, thermal/mechanical, APPSH build, and AI&T tooling needs under direction from senior engineers and IPT leads.
Develop drawing packages with appropriate dimensions, tolerances, materials, finishes, notes, and inspection features.
Apply GD&T and tolerance stack-up thinking appropriate to the part function and manufacturing method.
Design for manufacturability, assembly, inspection, cleanliness, handling, and integration constraints.
Work with vendors and internal teams to resolve drawing questions, fabrication issues, and fit/function concerns.
Support design reviews, peer checks, drawing release, ECOs, and configuration updates.
Create simple analysis, hand calculations, or engineering rationale to support designs.
Provide hands-on build, fit-check, and troubleshooting support in lab, shop, or AI&T environments.
Document design decisions and open issues clearly so higher-level owners can make fast decisions.
