YOUR FUTURE JOB
As a Senior Application Engineer for our Battery products, you will be the vital bridge between our cutting-edge silicon and our customers' end applications (such as Battery Management Systems for: EV, energy storage, and industrial packs).
You will leverage our understanding of battery management architectures to champion our unique innovations, demonstrating how they translate into tangible system-level benefits. Beyond advocating for the technology, you will take ownership of the software ecosystem by developing the essential low-level drivers, evaluation GUIs, and example code required to bring the hardware to life. Finally, you will support in providing hardware guidance to help customers successfully integrate the chip.
