Description

Position Summary We are seeking an experienced and creative Structural Engineer to join our rapidly growing power electronics team. You will be responsible for the structural design of our power conversion products from concept to mass production. The successful candidate will be a core member of the product development team with key responsibility for the product's manufacturability, reliability, thermal performance, and user experience. Key Responsibilities 1.Product Mechanical Design a.Lead the overall structural, exterior, thermal, and protection design for new products. b.Create 3D models, generate detailed 2D engineering drawings, and prepare all related structural design documentation. c.Demonstrate expertise in designing plastic injection molding and sheet metal processes. Select appropriate materials to optimize design for cost, manufacturability, and performance. 2.Thermal Design & Optimization a.Take ownership of product thermal management solutions. This includes heatsink design and selection, fan/cooling duct design, and application of thermal interface materials. b.Collaborate with thermal simulation engineers or directly use CFD software (e.g., FloTHERM, Icepak) to perform thermal analysis. Iterate and optimize the structural design based on simulation results to ensure power components operate within temperature limits under all conditions. 3.Safety & EMC Compliance Design a.Thoroughly understand and apply international safety standards (e.g., UL 1741, IEC 62109) to ensure designs meet requirements for creepage/clearance distances, flammability ratings, and grounding. b.Work closely with electronics and EMC engineers to ensure product passes EMC tests through structural means, such as shielding and grounding strategies. 4.Prototyping & Testing Validation a.Lead the build and assembly of prototypes and first articles from molds. Troubleshoot and resolve structural issues during assembly. b.Develop and execute structural validation test plans (e.g., vibration, shock, drop, thermal cycling, salt spray). Analyze test failures, identify root causes, and implement effective solutions. 5.Cross-functional Collaboration & Lifecycle Management: a.Work effectively with Hardware, Software, ID (Industrial Design), Procurement, Quality, and Manufacturing teams to resolve issues throughout the product development cycle. b.Support continuous improvement and cost reduction (VAVE) initiatives for mass-produced products. 我们正在寻找一位经验丰富、富有创造力的结构工程师，加入我们快速成长的电力电子团队。您将负责公司电力电子产品从概念到量产的全过程结构设计工作。成功的候选人将是产品开发团队的核心成员，对产品的可制造性、可靠性、散热性能及用户体验承担关键责任。主要职责（1）产品机械设计 •主导新产品的整体结构、外观、散热及防护设计。 •创建3D模型，生成详细的2D工程图，并准备所有相关的结构设计文档。 •精通塑胶注射成型或钣金工艺设计。合理选材，确保设计在成本、可制造性和性能上的优化。（2）散热设计与优化 •负责产品散热管理解决方案。包括散热器设计与选型、风扇/风道设计以及导热界面材料的应用。 •与热仿真工程师协作或直接使用CFD软件（如FloTHERM, Icepak）进行热分析，并基于仿真结果迭代优化结构设计，确保功率器件在所有条件下均能在温度限值内工作。（3）安规与EMC合规性设计 •深刻理解并应用国际安规标准（如UL 1741, IEC 62109），确保设计满足电气间隙、爬电距离、防火等级和接地要求。 •与电子和EMC工程师紧密合作，通过结构方法（如屏蔽和接地策略）确保产品通过EMC测试。（4）样机验证 •主导原型件制作与组装。解决装配过程中出现的结构问题。 •制定并执行结构验证测试计划（如振动、冲击、跌落、高低温循环、盐雾测试）。分析测试失败，定位根本原因并实施有效的解决方案。（5）跨部门协作与生命周期管理 •与硬件、软件、ID（工业设计）、采购、质量及制造团队高效合作，解决产品开发周期中各阶段出现的问题。 •支持量产产品的持续改进和成本降低（VAVE）计划。 Qualifications & Requirements 1.Education: Bachelor's degree or higher in Mechanical Engineering, Mechatronics or related field. 2.Experience: a.5+ years of experience in mechanical design within the power electronics industry (e.g., PV inverters, energy storage systems, server/telecom power supplies, UPS, variable frequency drives). b.Proven track record of independently designing and delivering structural systems for successfully mass-produced products. 3.Technical Skills: a.CAD/CAE Tools: High proficiency in 3D CAD software (SolidWorks, CREO/Pro-E, or Siemens NX).
