Summary(岗位介绍)

Facebook Reality Labs is a world leader in the design of virtual reality (VR) and augmented reality (AR) systems. Come work alongside technology visionaries and research scientists to create the technology that makes VR and AR pervasive and universal. The Cameras & Sensors (C&S) team gathers world class expertise and talent in photographic and machine vision cameras, imaging sensors, and depth, inertial, and bio sensing systems, and owns the development and validation for all these sensing systems across the whole AR, VR, & Portal product portfolios.

We are looking for an Analog Mixed Signal Designer to create innovative designs at the forefront of custom sensor technology, to enable breakthrough new depth sensing architectures delivering the best-in-class performance in small form factors and ultra-low power systems. The ideal candidate is enthusiastic about exploring and tackling new on-sensor compute architectures and sometimes ambiguous technical challenges, is engaged in deep collaboration across internal and external teams of passionate technologists that result in detailed depth sensor analyses, critical tradeoff evaluations, and sensor architectural execution strategies.

The scope of this role in the depth system architecture team will be a technical lead in creating, specifying, and reviewing new approaches to achieve high-end depth system performance in very constrained area and power efficiency requirements in the AR and VR space.
