Job Description: 

At Facebook Reality Labs (FRL), we are developing the future of Portal, wearable, virtual reality (VR) and augmented reality (AR) products. As a Liquid Crystal Technologies and Optics Engineer, you will be responsible for development and productization of precision optical components based on LC technologies that are at the core to delivering transformative experiences for next generation Facebook’s AR and VR products. You will join a team that is working on radically new concepts and approaches required because of new constraints imposed by advanced AR/VR devices. You will develop prototypes and products and establish new process capabilities with supply-chain partners and releasing product sub-systems that are fully hardened for high-volume manufacturing. We want people who work well in teams comprising a wide range of disciplines, who seamlessly transition between brainstorming big ideas and paying attention to those critical details that enable the technologies’ success. Based on a robust engineering background and a data driven approach, ideal candidates should demonstrate experience through a successful track record of bringing products from concept into mass production. We are currently seeking innovative talents with experience designing and modeling advanced liquid crystal designs for near-to-eye display applications. This is a full-time position and requires an advanced degree in optical engineering, physics, or similar, and a background in liquid crystals and polarization.
