Firmware Engineer, AR Audio

Facebook Reality Labs(FRL) is the world leader in the design of virtual and augmented reality systems. Come work alongside expert engineers and research scientists to create the technology that makes augmented reality (AR) pervasive and universal. Join the adventure of a lifetime as we make science fiction real and change the world. You're an engineer with deep embedded system knowledge, a passion for working on new hardware and strong leadership skills. You're comfortable working with a wide variety of hardware devices, working with a team to rapidly deliver reliable high performance firmware.
At Facebook Reality Labs(FRL) you will design, build and test firmware systems for future augmented reality experiences. You will join a world-class team of experts exploring new audio AR concepts through rapid prototyping. Firmware for AR systems spans multiple target classes, requiring deep collaboration across engineering disciplines (electrical, mechanical, acoustic, firmware and software) and directly impacting user immersion.
we're looking for people who quickly solve problems, generate big ideas, work in new technology areas, drive concepts into prototypes, and envision how those prototypes transition to high-volume consumer products.
