Research Scientist, Optical Systems

About the role

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. Responsibilities 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 Qualifications 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
