Job description

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. Develop and optimize techniques and processes for the fabrication of diffraction gratings and light guides on organic substrates Perform nanostructure patterning using e-beam lithography, stepper lithography, and nanoimprint lithography techniques Develop and characterize dry etch and wet etch processes for precision waveguide fabrication Deposit dielectric thin films using sputtering, atomic layer deposition (ALD), and e-beam evaporation techniques Perform metrology and characterization using AFM, SEM, optical profilometry, and spectroscopic methods Collaborate with optical designers, materials scientists, and integration teams to translate design requirements into manufacturing processes Document, develop standard operating procedures, and contribute to IP generation Identify and troubleshoot yield-limiting defects and process excursions Support technology transfer from R&D to pilot-scale and high-volume manufacturing PhD in Chemistry, Polymer Science, Chemical Engineering, Materials Science, Physics, or related field Hands-on experience with nanofabrication techniques, including E-beam lithography, optical steppers, and dry/plasma etching Experience with thin-film deposition methods (sputtering, ALD, or e-beam evaporation) Proficiency with metrology tools such as AFM, SEM, and optical characterization systems Demonstrated experience in developing and optimizing fabrication processes from development through qualification Familiarity with organic/polymer substrates and their processing challenges (thermal budget, CTE mismatch, surface energy). Experience with nanoimprint lithography (NIL) or roll-to-roll patterning 2+ years of relevant industry experience, or Master's degree with 5+ years of relevant industry experience Background in AR/VR optics, holographic optical elements, surface-relief gratings, or photonic devices Experience fabricating diffractive optical elements, waveguides, or photonic structures Fundamental understanding of light-matter interaction, photonic nanostructures, and device physics Experience scaling processes from R&D prototyping to pilot production Knowledge of optical thin-film design and coating characterization
