Reality Labs (RL) focuses on delivering Meta’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. Meta 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.

You will use your background in Machine Learning (ML) to enable efficient hardware (h/w) acceleration of ML algorithms for Computer Vision (CV) and Image Processing in AR and VR devices. You will also have an unique opportunity to optimize production systems, as well as help future-proof our silicon and software by proactively understanding state of the art research and develop hardware or software solutions to mitigate inefficiencies. To be successful in this role, you should possess strong software development skills, familiarity with ML algorithms and framework/toolchains and hands-on experience in s/w-h/w co-design, especially in the context of ML.

This is a 12 week internship with various start dates throughout the year.
