Optical Engineer, Waveguide Experiments

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 Waveguide Experiments team for a 12‑month fixed‑term contract at Snap Inc!

• Develop new experimental methods to deepen understanding of AR waveguide physics
• Build and apply models of optical and physical phenomena to interpret lab experiments
• Design, build, and automate optical setups
• Run experimental analysis of wave guides using both proprietary and commercial tools
• Perform root cause analysis of failures of waveguide displays
• Perform experiments on diffractive nanostructures to make improvements in correlation between measurements and predictions and help drive improvements in optical performance
• Collaborate with cross‑functional engineering teams on waveguide bring‑up, debugging, and performance improvement

• Strong theoretical foundation in optics and diffraction theory (including physical and geometric optics, imaging, radiometry, photometry, colorimetry, statistics etc.)
• Solid understanding of polarization theory and experimental techniques
• Experience with interferometry and phase retrieval methods
• Strong scripting and data analysis skills in Python (or similar)
• Proficient in error analysis of experiments
• Experience working in an optical lab environment, hands‑on experience setting up and aligning optical systems (lasers, fiber optics, detectors, cameras)
• Skilled in equipment automation and control
• Experience of nanoscale metrology for evaluating diffractive structures (SEM, AFM)
• Strong planning and organisational skills for high‑risk R&D projects
• Adaptable to rapid changes in project scope or timelines
• Clear communicator with strong reasoning and collaboration skills
• Flexible and team‑oriented with a proactive, problem‑solving mindset appropriate for a dynamic R&D environment

• Bachelor’s or Master’s degree in Optical Engineering, Physics, Electrical Engineering, or a related Engineering field.
• 3+ years of hands‑on research experience in optical metrology

• PhD in Optical Engineering, Physics or a related field
• Theoretical and experimental research experience in diffractive AR wave guides
• An understanding or background in the manufacture of diffractive or nanophotonics optical devices such as nanophotonics mastering, replication by nanoimprint lithography or photolithography, and optical coatings
• Experience with optical system design tools such as Zemax, CodeV, FRED, ASAP
• Experience of using wave optical modelling tools such as Lumerical, RSoft, COMSOL, MEEP

If you have a disability or special need that requires accommodation, please don’t be shy and provide us some information.

"Default Together" Policy at Snap:
At Snap Inc. we believe that being together in person helps us build our culture faster, reinforce our values, and serve our community, customers and partners better through dynamic collaboration. To reflect this, we practice a “default together” approach and expect our team members to work in an office 4+ days per week.

At Snap, we believe that having a team of…
