Research Scientist, Optical Systems 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.
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 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 structures
