AR Glass Substrate Expert, Glass Melting & High Index Glass Process Development

What you'll do

• Research and develop high-index optical glass compositions optimized for AR applications.
• Design and implement thickness and flatness control strategies to ensure substrate quality.
• Develop advanced metrology and SPC systems to monitor manufacturing performance.
• Transition lab-scale processes to 300mm wafer platforms and high-volume production.
• Collaborate with vendors to establish robust process windows and cost structures.
• Partner with optics and photonics teams to integrate substrates into waveguide designs.
• Drive the co-optimization of materials, design, and processes for color uniformity.
• Contribute to patents and internal documentation to define next-generation substrate roadmaps.

What we're looking for

• MS or PhD in Materials Science, Glass Science, Applied Physics, or a related field.
• Proven expertise in glass melting and forming technologies.
• Hands-on experience with high-index glass development and optical-grade substrate processing.
• Familiarity with NIL vs. etched grating processes and AR waveguide integration.
• Strong understanding of refractive index engineering and optical performance metrics.
• Proficiency in metrology for thickness, flatness, and transmitted wavefront.
• Ability to scale processes from prototype to mass production.
• Experience with AR/MR waveguide substrates, thin-glass handling, CMP, coatings, or supplier engagement (preferred).
