Staff Thermal Design Engineer
Sanmina-SCI Systems de México, Secaucus, NJ, United States
About The Role
The 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 base.
In 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.
