Amazon China is an inventive research and development company that designs and engineers high-profile consumer electronics products, like the Kindle, Kindle Fire, Fire TV, and Echo, etc. The products we design and engineer are easy-to-use and offer users benefits that are only made possible through tightly integrated digital technologies and wireless connectivity.
The Senior Mechanical Process Engineer (MPE) — Injection Molding works closely with teams located in both the US and China throughout the design cycle. As a member of the MPE team, you will be responsible for developing injection molding processes for mechanical parts, providing DFM (Design for Manufacturability) recommendations to the design team (ID & PD), driving mold engineering studies, and improving part yield rate and cosmetic quality. You will also be responsible for closely monitoring and driving the above activities at injection molding suppliers.
In addition, you will work closely with the PE TPM (Product Engineering Technical PM) team on giving timely feedback of technical risk related to molding processes, and continuous communication of the status of engineering issues throughout the product development cycle to a cross-functional audience. You will be the primary contact window for injection molding technical issue resolution across the supply base.
The Role:
- Identify and develop injection molding processes for mechanical plastic parts, including process parameter optimization, mold flow analysis review, and cosmetic defect resolution
- Review and develop injection molding process flow, including mold design review, tooling fixture concept, gate/runner design, and DFM feedback
- Develop supplier injection molding process capability through continuous engagement, engineering studies, and DOE (Design of Experiments)
- Provide design feedback and recommendations on wall thickness, draft angles, rib/boss design, undercuts, parting line placement, and tolerances for injection molded parts
- Drive and approve technical data documentation throughout the development cycle including FAI, Cpk, Cmk, GR&R, mold flow analysis reports, and DFM
- Drive technical issue resolution at injection molding suppliers throughout the development cycle (e.g., sink marks, warpage, weld lines, short shots, flash, cosmetic defects)
- Mentor and develop junior engineers on injection molding best practices
- Identify technical risks related to mold tooling and injection molding processes, and define mitigation plans
- Travel domestically and internationally to supplier sites (mold makers and injection molding facilities) as projects require
