Summary（岗位介绍）

At Meta Reality Labs, we’re developing the future of augmented and virtual reality. We are looking for a wide range of expertise within Wireless System Engineering to join the wireless team at Meta Reality Labs. You will be a key member of a team of innovators, working on cutting-edge wireless technologies and aimed at pushing beyond the state of the art for developing wireless technologies that will enable the future of AR/VR.

AR/VR Wireless Team focuses on delivering Meta's vision through Augmented Reality (AR). Compute power requirements of Augmented Reality require custom silicon. Our Wireless 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 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 transistor, through architecture, to firmware, and algorithms.
