Reality Labs is seeking a Nanofabrication Research Engineer to advance the development of next-generation optical components for augmented and virtual reality devices. In this role, you will design, fabricate, and characterize nanoscale optical structures — including diffractive optical elements, waveguides, and metasurfaces, MEMS devices, photonic integrated circuits, spatial light modulators — that are central to enabling lightweight, high-performance AR/VR wearables. You will work at the intersection of photonics, materials science, and semiconductor fabrication to translate research concepts into manufacturable optical solutions that define the future of spatial computing.
