Meta Reality Labs is seeking a Research Scientist, with experience in waveguide fabrication and process development, to advance optical systems research for next-generation augmented reality devices and advanced computing systems. In this role, you will work at the intersection of nanofabrication, materials science, and optical engineering - directly contributing to the hardware that will power Meta's AR glasses and displays. This is a fundamental research role driving a long-term research roadmap to establish the feasibility of breakthrough optical technologies for future product generations.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 manufacturingPhD 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 2+ years of relevant industry experience, or Master's degree with 5+ years of relevant industry experience Fundamental understanding of light-matter interaction, photonic nanostructures, and device physics Knowledge of optical thin-film design and coating characterization Experience scaling processes from R&D prototyping to pilot production Background in AR/VR optics, holographic optical elements, surface-relief gratings, or photonic devices 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 Experience fabricating diffractive optical elements, waveguides, or photonic structuresMeta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today-beyond the constraints of screens, the limits of distance, and even the rules of physics.Meta is proud to be an Equal Employment Opportunity employer.
