Job Description:

You can submit up to three job applications every 90 days. Be sure to apply for roles that strongly match your skills and work experience.

Facebook Reality Labs 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 Embedded Software Engineer to support development of ASICs custom-designed for Facebook Reality Labs products. The successful candidate will be part of a team that includes algorithm, user experience, software, firmware and silicon experts. The ideal candidate will understand low-level embedded software development for custom low-power SoC. This is a full-time position.
