Principal Firmware Engineer; Bluetooth Lower Stack
We’re Working on behalf of a leading maker of RF ICs for wireless applications. They recently acquired Avnera , a top maker of ASICs and DSP chips that go into Bluetooth applications. Avnera focuses on the Audio SoC (chip) and theRadio SoC. These chips go into Gaming, Music Listening and other short range wireless Smartphone applications.
They are looking for a Principal Firmware Development Engineer, who will develop Firmware to program the ASIC and drive the Hardware. The Firmware is for the Lower Bluetooth stack, so the Wireless Rdio Interface and , Baseband Link layer are the keys.
We need a BSEE or CS or higher degree, with 5-15 or more years of experience in Firmware Design for Wireless Lower Stack.
Competitive Salary, plus bonus, RSU.
Ideally based in Portland OR, but a senior FW Developer with 7-10 + years of Lower Stack expertise can work anywhere in the USA.
This position will be working as part for the core SDK team developing and deploying embedded firmware libraries to support various ASIC system designs. As part of the firmware team that works in conjunction with the digital and analog hardware teams to define, implement, validate, and support custom system on chip designs to implement wireless and mobile audio designs. The environment and libraries created in this process are then provided to applications teams to provide a foundation for a wide range of product designs.
This position is with the general SDK support team but the primary effort will be focused on supporting the integration of new Bluetooth hardware and software designs into the SDK infrastructure as well as development to enable advanced Bluetooth functionalities.
Tasks you will be responsible for include:
Work with internal hardware and firmware teams to define system hardware drivers and libraries.
