SOC Architect, Reality Labs Silicon

Reality Labs focuses on delivering Meta’s vision through creating advanced AR/AI enabled wearables. The compute performance and power efficiency requirements of wearables require custom silicon. Reality Labs Silicon team is driving the state-of-the-art forward with breakthrough work in AI, augmented reality, computer vision, machine learning, graphics, displays, and sensors. Our chips will enable wearable devices where our real and virtual worlds will mix and match throughout the day. We believe the only way to achieve our goals is to look at the entire stack, from transistors, through architecture, firmware, and algorithms.As an SoC Architect, you will play a key role in driving top-level chip architecture that meets the power and size constraints of wearable devices., 1.
