Algorithm & DSP Engineer

Facebook AR/VR focuses on delivering Facebook's vision through Augmented Reality (AR) and Virtual Reality (VR). The compute performance and power efficiency requirements of Virtual and Augmented Reality require custom silicon. Facebook Silicon team is driving the state of the art forward with breakthrough work in computer vision, machine learning, mixed reality, graphics, displays, sensors, and new ways to map the human body. Our chips will enable AR and VR devices where our real and virtual world will mix and match throughout the day. We believe the only way to achieve our goals is to look at the entire stack, from transistor, through architecture, to firmware and algorithms.
We are seeking an Algorithm & DSP Engineer who is excited about introducing ground breaking capabilities in the fields of computer vision, machine-learning and imaging, through the development of specialized HW components, and the adaptation of algorithms to HW implementation. The successful candidate will be required to architect custom ICs/ASICs in close collaboration with the groups developing the algorithms, system software and SoCs.
This is a full-time position based in our Menlo Park campus, CA or Redmond, WA.
