Snap Inc is a technology company. We believe the camera presents the greatest opportunity to improve the way people live and communicate. Snap contributes to human progress by empowering people to express themselves, live in the moment, learn about the world, and have fun together. The Company’s three core products are Snapchat, a visual messaging app that enhances your relationships with friends, family, and the world; Lens Studio, an augmented reality platform that powers AR across Snapchat and other services; and its AR glasses, Spectacles.

The Spectacles team is pushing the boundaries of technology to bring people closer together in the real world. Our fifth-generation Spectacles, powered by Snap OS, showcase how standalone, see-through AR glasses make playing, learning, and working better together.

Snap’s camera supports real friendships through visual communication, self expression and storytelling. Moving forward, our camera will play a transformative role in how people experience the world around them, combining what they see in the real world, with all that’s available to them in the digital world.

We’re looking for an Optical Engineer to join our team at Snap Inc!

• Engineer the next generation of augmented reality hardware, designing high-performance AR glasses that blend cutting-edge technology with the real world.
• Collaborate with optics, materials science, and manufacturing to create breakthrough products and scale precision dispensing technologies critical to AR display and component architecture.
• Develop and optimize advanced dispensing and coating processes, with emphasis on inkjet printing and related methods such as jet dispensing, spray coating, dip coating, aerosol jet printing, micro-dispensing, and slot-die as appropriate.
• Own end-to-end process development including tool setup, recipe definition, maintenance, waveform tuning, substrate preparation, curing, and rigorous process control.
• Evaluate and compare dispensing approaches for functional layers (e.g., optical clear adhesives, polymer layers, micro-structured materials).
• Understand rheology, surface tension, wetting, and adhesion of ink/dispense materials and how these characteristics affect method choice and performance.
• Design and implement metrology and characterization capabilities to measure film thickness/uniformity, geometry, surface morphology, alignment, optical performance, and defect modes.
• Analyze process data using DOE, SPC, regression, and yield modeling to drive improvements in uniformity, throughput, repeatability, and yield.
• Collaborate cross-functionally with optical engineering, mechanical design, materials science, reliability, and assembly teams to integrate new dispensing processes in AR module manufacturing.
• Work with internal and external partners to develop tools for scaling up processes for mass production.
• Support long-term process roadmap development, identify technology gaps, and lead evaluations of new dispensing tools or methods for next-generation AR hardware.

• Expertise in inkjet printing, including waveform tuning, drop formation dynamics, material compatibility, and print quality control.
• Practical experience with industrial printheads and familiarity with control software and drop watching systems.
• Broad understanding of additional precision dispensing / coating methods such as jet dispensing, micro-dispense, aerosol jet printing, spray coating, dip coating, blade/slot-die coating, or similar techniques.
• Strong foundational grasp of fluid mechanics, surface science, and wetting, and how material properties influence deposition outcomes.
• Good understanding of thin film characterization and metrology, including profilometry, interferometry, reflectometry, optical microscopy, defect inspection, and thickness measurement.
• Strong experimental design, analytical, and problem-solving abilities; capable of independently driving complex R&D investigations from concept to completion.
• An effective communicator who can collaborate with multidisciplinary teams and clearly document processes, findings, and specifications.

• Master’s (or higher) degree in Materials Science, Chemical Engineering, Mechanical Engineering, Applied Physics, or a related technical field.
• 5+ years of hands-on experience with inkjet printing, dispensing, coating, micro-fabrication, printed electronics, or precision deposition processes.
• Experience working effectively in R&D labs, cleanrooms, or controlled-environment manufacturing settings.

• PhD in a relevant discipline or 10+ years of extensive experience in precision dispensing, printed electronics, advanced manufacturing, or display technology.
• Proven experience evaluating and selecting between multiple deposition/coating techniques based on complex material, optical, and mechanical requirements.
• Familiarity with AR/VR optical components, waveguides, nanoimprinting, thin-film deposition, bonding, and dry etching processes.
• Experience in process transfer, successful scale-up to mass production, yield optimization, and implementation of inline metrology.
• If you have a disability or special need that requires accommodation, please don’t be shy and provide us some information.
