## Description

At ABB , we help industries run leaner and cleaner—and every person here makes that happen. You’ll be empowered to lead, supported to grow, and proud of the impact we create together. Join us and help run what runs the world. This position reports to: Chapter Lead __ Your role and responsibilities In this role, you will have the opportunity to contribute to ABB's success through technology, product, and system development in power electronics. Each day, you will apply your expertise independently and as part of a cross-functional R&D team, identifying and implementing innovative solutions for demanding switching applications. This role is contributing to the EL Smart Power business in Xiamen China. You will be mainly accountable for: Lead thermal management solution design & selection for SSCB: feasibility assessment and decision-making among natural convection, forced air-cooling, liquid-cooled cold plates, and immersion cooling pathways Develop thermal network models based on power device losses (conduction loss, switching loss, short-circuit conditions) and establish junction temperature budget; define cold plate thermal resistance, interface material thermal resistance, and cooling liquid flow rate/temperature rise requirements Optimize heat dissipation pathways considering SSCB's high steady-state conduction losses and high power density; balance power density, cooling efficiency, and volume footprint Lead cold plate flow channel design (topology, fin density, flow distribution structures, pressure drop optimization); complete - -CFD simulation and flow resistance validation Design liquid cooling pipelines, manifolds, quick-disconnect connectors, and sealing structures; address leakage, condensation, corrosion, and cooling fluid compatibility issues Drive thermal interface material (TIM) selection between cold plates, power modules, and busbars; define assembly processes and control contact thermal resistance and assembly consistency Support liquid cooling system degassing, fluid replenishment, maintenance, and fault diagnostics design Independently or lead CFD thermal simulations (Icepak, FloTHERM, ANSYS Fluent, etc.); deliver junction temperature, temperature distribution, flow field, pressure drop, and thermal stress results- Conduct thermo-mechanical coupling analysis to evaluate power cycling, thermal expansion mismatch, solder joint/interface material fatigue, and structural thermal stress Define thermal test protocols (thermocouple placement, IR thermography, flow rate/pressure drop testing); calibrate simulation models against experimental data Complete 3D modeling and 2D drawings of cold plates, pipelines, power modules, and housings; conduct tolerance and assembly analysis Collaborate with manufacturing and suppliers to complete brazing/friction stir welding, sealing, machining, and DFM (Design for Manufacturability) analysis for production ramp-up Coordinate with power electronics, electrical, and testing teams to balance low parasitic inductance, insulation coordination, thermal performance, and maintainability Delivery Desigen and implementing design review with cross function. Making prototype and validation solution, test to validate the design fulfill the technical requirement, following type test and ensuring the product can be released to market.Ensure designs comply with a blend of standards and Mojor Classification society roules (e.g.,CE，CCC) Building test assemblies, running experiments, and recording test data, Analyzing test data and optimizing the solutions,Preparing internal and external technical reports. As Agile Team member, active take charge and contributing to the business target, independent achieve own task on time,cost and quality Communicating/cooperating with oversea and local stakeholders to maintain products and manage projects. Author detailed technical specifications and decimations for LV switch and associated equipment. Implement technical clarifications and customer requirement
