Role Number:

Do you have a passion for building innovative HW/SW for controlling modern RF transceivers? Do you enjoy hands-on, cradle-to-grave experience for building state-of-the-art cellular SoCs? In this role, you will have the opportunity to engage in architecture stages, and work with various teams to design, implement, verify, validate, bring-up, and productize advanced transceiver architectures. As part of an elite RF architecture team, you will define HW and FW control systems for real-time control, transceiver calibration, and more. Join us and help to innovate new wireless systems technologies that continually outperform the expectations!

Description

As a Cellular RF Control System Engineer, you will model and implement control flows for modern RF transceivers. You will understand and map system requirements and algorithms to HW/FW architectures to ensure development of state-of-the-art design covering all aspects of the system including functionality, performance, power, latency, area, and debuggability. You will develop simulation models to accurately capture architecture functionality, analog, digital, and FW interfaces, and play an active role in bring-up, and debug of silicon. This position requires strong collaboration with SoC, MAC, PHY, RF HW, RF FW, and SW teams to ensure the end-to-end system requirements are met. You will also have a critical hands-on role in pre- and post-silicon verification, validation, and bring-up of silicon, to support productization.
