As a GPU performance modeling engineer in the Silicon Technologies group, you will focus on developing cycle-approximate performance models in C/C++. You will collaborate closely with architects and designers to understand the units being modeled and analyze performance results. This role is critical in supporting the hardware team during model and design performance bring-up. You will work on creating elegant solutions to complex challenges in GPU design and manufacturing.
