Job Description

About The RoleThe StaffThermal Design Engineer is responsible for assisting in the development of key thermal components & systems from concept to engineering release of new products. The focus is on running server system thermal tests using data acquisition equipment, thermal stress test software, and external power control equipment. The thermal engineer troubleshoots thermal and/or airflow issues in new and existing product lines using empirical data and commercial CFD software. The Sr. Staff Thermal engineer plays an active role in developing thermal components using 3D CAD software and advanced engineering analysis. A candidate for this role will be responsible for owning thermal design and optimization for new hardware and evaluating thermal technology. The involved system design across compute and storage devices, evaluating and advancing current and emerging thermal technologies, from liquid cooling to thermal critical components, and optimizing the hardware for high performing, efficient data center operation. The engineer will be responsible for solving heat transfer problems occurring in complex subcomponents or full hardware systems, using comprehensive thermal design fundamentals and analytical tools. The ideal candidate would have the ability to work with other function teams in ZT and vendors to strength their knowledge addition, the thermal engineer provides regular Q&A and on-site support to ZT Systems’ manufacturing engineering group as well as technical support for customers.What You Will DoCreate analytical and numerical models by CFD or relevant simulation tools to describe system thermal for new projectsCollaborate with cross-functional teams throughout the product development process, from conceptualization to prototyping and productionWork with the engineering team to optimize the thermal performance of servers using empirical data and bench test methodsDevelop and execute test plans to measure thermal performance/efficiency of hardware and thermal technologiesResponsible for full cycle program / project management of key thermal components from engineering design to new product releaseDesign and investigate innovative thermal cooling solutions for server/rack level productsInterface with the Firmware team to implement fan speed control algorithm.Optimize airflow speed, volume, and flow paths to meet customer and components requirementsProactively resolve any performance issues that arise, ensuring the delivery of high-quality solutionsAnalyze and solve technical problems/issues in a fast-paced environmentProduce engineering documents that include design drawings, thermal reports, installation manuals from test and simulation data/resultFocused on the pursuit of continuous improvement to maintain the highest quality standardsSelect/decide the appropriate methods and plans to verify thermal related issue to ensure good system thermal performanceEngage with external vendors including ODM and component vendors on design, test and productionLiquid cooling components survey, study, test and verifySupport new and existing product lines verify/confirm thermal and/or airflow related issues and provide solutionsSupport procurement team to identify and manage heat sink, air mover and liquid cooling vendorsWhat You BringBachelor's Degree in Mechanical Engineering, Industrial Engineering, or Electrical Engineering.
