Mechanical Engineer_High Voltage_TN_202609_035 高压机械设计工程师

Responsible of mechanical design for an integrated x-in-1, 800+ V high-voltage control module for NEVs, ensuring robust packaging, thermal/structural performance, HV safety, EMC-ready interfaces, sealing/IP integrity, and manufacturability from concept through SOP and across derivatives.

Responsibilities

Break down OEM customer technical specifications into mechanical requirements, boundary envelopes, and Interface Control Documents; Lead concept trade-off studies and mechanical architecture of high-voltage X-in-1 units; Direct space-claim, vehicle-level packaging studies, and bracket/mounting interfaces; Design structural aluminum die-cast housings, extruded cooling plates, busbars, injection-molded parts, and EMI shielding covers using 3D CAD; Apply DFM/DFA/DFT rules to optimize production yields, cycle times, and scrap rates; Perform tolerance stack-up analyses and create 2D manufacturing drawings following GD&T standards; Coordinate with simulation specialists on CFD and FEA analyses; Ensure structural designs withstand vehicle environments (shock, vibration per ISO 16750-3); Select and integrate Thermal Interface Materials; Ensure mechanical compliance with automotive HV safety directives (ISO 6469, GB/T 18384, ECE R100); Engineer sealing concepts to achieve IP67 and IP6K9K; Lead Design FMEA (DFMEA) per AIAG-VDA standards; Guide mechanical suppliers through feasibility reviews, tooling trials, and PPAP approval; Support prototype builds (A/B/C samples), resolve assembly problems, drive ECRs, and implement Root Cause Analysis (8D, Ishikawa, 5-Why); Act as technical lead for production lines during line setup and end-of-line air-leak testing; Lead mechanical risk identification and mitigation; Ensure compliance to applicable standards and customer specs; Plan and track DVP testing; Coordinate APQP/PPAP for mechanical parts and assemblies; Set and track cost/weight targets for mechanical content and lead VA/VE workshops; Provide clear status, risk, and decision logs to leadership and customers; Manage issue/action registers, KPI dashboards, and lessons learned

Requirements

Bachelor's or Master's degree in Mechanical Engineering, Mechatronics, Automotive Engineering, or equivalent; 5+ years in mechanical development for automotive high voltage control modules; Demonstrated delivery of enclosure/cooling/sealing-heavy products under automotive quality systems (APQP, PPAP, IATF 16949); Working knowledge of 800V-1000V and HV safety and mechanical topics (creepage/clearance, CTI-driven materials, UL94 flammability); Background in die casting and welded aluminum housings, sealing systems (O-rings, form-in-place gaskets, venting), and thermal interface materials/potting; Launch experience for integrated multi-function HV modules (e.g., OBC + DC/DC + PDU/inverter controls) with tight packaging and thermal zoning; Familiarity with EMC from a mechanical perspective (shielding joints, grounding continuity); Proficiency with CAD/PLM-driven release processes, Creo and Windchill, and change control (ECR/ECN); Strong cross-functional collaboration, supplier management, and communication skills; Fluent English communication
