Coursework or project experience in geometrical and physical optics, imaging, or radiometry Experience with at least one optical design or analysis tool (e.g., Zemax, CODE V, LightTools, FRED, or comparable) Programming and data analysis experience in Python or MATLAB Must obtain work authorization in country of employment at the time of hire, and maintain ongoing work authorization during employment Intent to return to full-time degree program after completion of the internship Coursework or research in imaging systems, illumination design, stray light analysis, or computational imaging Hands-on optical lab experience with instrumentation such as spectrometers, interferometers, scatterometers, lab microscopes, or MTF test benches Familiarity with optical performance metrics and measurement techniques (MTF, BSDF, surface form and roughness, distortion, transmitted wavefront error) Exposure to non-sequential or stray light simulation, tolerance analysis, or Monte Carlo yield analysis Familiarity with optical materials, thin-film coatings, or injection-molded and formed optical components Interest in applying machine learning or automation to optical design, simulation, or data analysis workflows Experience communicating technical results clearly to a multidisciplinary audienceMeta builds technologies that help people connect, find communities, and grow businesses. You will own a focused technical project with a real deliverable on our roadmap - building optical models, quantifying design trade-offs, correlating simulation against measurement, and presenting your findings to the engineers who will carry the work forward.
