Research Scientist, Optical Systems

Reality Labs is seeking an Optical Scientist to drive the research and development of advanced optical systems for next-generation augmented and virtual reality devices. In this role, you will design and characterize optical components and systems — including waveguides, display optics, imaging systems, and light-field architectures — that are foundational to delivering high-fidelity visual experiences in lightweight AR/VR wearables. You will bridge fundamental optical science and applied engineering, translating novel photonic concepts into scalable solutions that shape the future of spatial computing and immersive human-computer interaction.
