Bilingual in Mandarin Chinese a plus

Responsibilities

Own the mechanical design and integration of the surrounding system, including liquid cooling loops, drawer integration, manifolds, coolant distribution assemblies, fluid routing, and mechanical interfaces to the cold plates. Collaborate with the Thermal Engineer responsible for detailed cold plate design.
Define and influence early mechanical architecture in collaboration with thermal system architects and cross-functional engineering teams.
Own top-level assembly management, including loop layout, packaging strategy, integration architecture, component interface definition, top-level assembly CAD, including 2D and 3D models, final assembly drawings, engineering documentation, and release packages for system-level components and assemblies.
Define system-level cold plate envelope and interface requirements, review cold plate module drawings against system requirements, and perform fit-up, compatibility, and interference checks across the integrated assembly.
Own system-level mounting screw selection, hose and tube routing, barb strategy, manifold integration, and associated mechanical interface definition.
Support global and domestic builds, both onsite and remote, in prototype, mini-build, SOP, and main build cycles through POC, P1, P2, EVT, DVT, and mass production to drive rapid issue resolution and product readiness.
Identify, assess, track, and drive closure of system-level technical risks.
Create system and assembly drawings with inspection criteria, GD&T specifications, and manufacturing acceptance standards such as FAI and SPC callouts.
Manage system component and assembly releases throughout the product lifecycle, including engineering change implementation and release coordination.
Contribute system-design input to Design for Manufacturability (DFM) and Design for Assembly (DFA) reviews led by operations and manufacturing partners.
Perform system-level tolerance stack-up and variation studies covering assembly fit, component interfaces, packaging, and integration requirements, while collaborating with Thermal Engineering on TIM-gap and thermal-interface tolerance requirements.
Review system and assembly-level FAI, SPC, metrology, process capability, Cp/Cpk, and production data to support system design decisions, while coordinating with Thermal Engineering on data specific to individual cold plates.
Develop the initial assembly and disassembly strategy, system assembly documentation, and loop-level SOP content, then coordinate transfer and continued ownership with Process and Manufacturing Engineering.
Own and maintain the system-level bill of materials and coordinate interfaces with individual cold plate bills of materials.
Develop build strategies that support successful transition from prototype through high-volume production.
Support integration activities and manufacturing implementation at customer and contract manufacturing sites.
Work directly with customers to define system requirements, review concepts, communicate system-level technical trade-offs, and support deployment activities.
Conduct system-level failure analysis and root cause investigations and implement corrective actions across design, supplier, and manufacturing functions.
Collaborate closely with Thermal Architecture and Engineering, Manufacturing and Process Engineering, Quality, Reliability, Test Engineering, Operations, Supply Chain and Sourcing, Program Management, Business Unit leadership, customer engineering teams, suppliers, and domestic and international manufacturing partners to deliver production-ready liquid cooling solutions at scale.
