Product Design Engineer

Product Design Engineer (Mechanical)Headquartered in the United States, TP-Link Systems Inc. is a global provider of reliable networking devices and smart home products, consistently ranked as the world's top provider of Wi-Fi devices. The company is committed to delivering innovative products that enhances people's lives through faster, more reliable connectivity. With commitment to excellence, TP-Link serves customers in over 170 countries and continues to grow its global footprint.TP-Link Systems Inc. is seeking a talented and driven Product Design Engineer (Mechanical) to join our team. In this role, you will own the mechanical system architecture (internal layout, construction strategy, and assembly approach) and detailed mechanical design of next-generation consumer networking or smart home products.You will take products from early concept through high-volume manufacturing, working closely with Industrial Design (ID), Electrical/Hardware Engineering, NPI/Operations, and external suppliers/contract manufacturers to deliver production-ready designs.Key ResponsibilitiesOwn and drive product-level mechanical system architecture, including internal layout, part breakdown strategy, construction strategy, fastening/joining strategy, datum scheme, tolerance strategy, and serviceability.Partner with Industrial Design (ID) to translate design intent into manufacturable mechanical solutions while balancing aesthetics, usability, reliability, schedule, and cost.Collaborate with Electrical/Hardware Engineering to define mechanical interfaces and constraints, including PCB outline and mounting, connector/I-O access, assembly datums, fastener strategy, and key keep-outs (as applicable).Support thermal and EMI-related mechanical integration, including thermal conduction/heat-spreading paths, shielding strategy implications (contact/compression features, gasket interfaces, conductive coatings), and grounding/contact reliability across tolerance and assembly variation.Create and release deliverables using PTC Creo (Creo Parametric): 3D CAD, 2D drawings, specifications, and (preliminary and released) BOMs; apply GD&T and tolerance stack-up on critical interfaces.Plan and support prototype builds and validation (EVT/DVT/PVT or equivalent): define build objectives and acceptance criteria; evaluate fit/function, cosmetic, key dimensions, and assembly robustness; drive issue closure through subsequent builds.Lead supplier/toolmaker engagement including tooling kick-off and T0/T1/Tn iterations; coordinate mold tuning and dimensional/assembly issue closure with suppliers/CMs.Drive DFM/DFA decision-making across manufacturing processes (injection molding, CNC machining, sheet metal, die casting, secondary ops/finishes), including cost/schedule trade-offs.Own documentation quality and change discipline: release and maintain drawings/BOMs and drive Engineering Change Orders (ECOs) with clear revision control and supplier communication.Participate in root-cause analysis and corrective actions for mechanical issues found during builds, in production, or from field returns.Mentor early career engineers through design reviews, best practices, and hands-on coaching (scope/expectations vary by leveling).
