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
