• Apply design‑for‑manufacturing principles for machined, molded, and fabricated parts
• Perform tolerance stack‑ups and support design validation
• Prepare models for prototyping, 3D printing, and engineering analysis
• Support prototype builds, testing, and product validation activities
• Participate in engineering change and documentation release processes
• Collaborate cross‑functionally with engineering, manufacturing, quality, and supply chain
• Provide technical guidance to junior designers as needed
