Reality Labs at Meta 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 & Depth (C&D) 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.

As a tech lead for technology incubation on the depth architecture team, you will own and drive next-generation technologies from initial concept, early system prototyping, and experiential validation. A successful candidate will have a passion for exploring and defining innovative designs at the forefront of custom sensing technology, to enable breakthrough new 3D 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 challenges associated with chipset architecture and integration, adding clarity to sometimes ambiguous technical problems, 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 sensing architecture team will focus on researching, creating, specifying, and developing depth sensing technology to achieve high-end performance in very constrained area and power efficiency requirements in the AR and VR space.
