Nanophotonics Engineer, Plasma Etching

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 , a visual messaging app that enhances your relationships with friends, family, and the world; , an augmented reality platform that powers AR across Snapchat and other services; and its AR glasses, .

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.

We're looking for a Nanophotonics Engineer to join the Spectacles team!

What you’ll do:

Develop, optimise and characterise plasma etching processes such as RIE and ALE in silicon nitride and related materials and with a focus on nanophotonics devices

Design and execute experiments to understand etch mechanisms, selectivity, and profile control for nanoscale structures

​​Utilise process simulation tools (e.g., Coventorware, Sentaurus, SEMuator 3D or similar) to model and predict etch behavior and support of interpretation results

Work with internal and external partners to develop recipes and bring up materials for associated processes such as nanoimprint lithography, magnetron sputtering, PECVD, etc.

Employ a range of metrology techniques (e.g., SEM, AFM, ellipsometry, reflectometry) for in-depth characterisation of material properties and measurement of nanoscale geometry

Analyse experimental data, troubleshoot issues, and implement corrective actions to improve the process and device performance

Collaborate closely with internal teams as well as external partners to integrate the etch processes with the overall waveguide manufacturing flow

Document experimental procedures, results, and process specifications in detail

Identify opportunities to optimise or even develop materials, tools, and processes for scaling towards mass manufacturing

Knowledge, Skills & Abilities:

Strong theoretical understanding of plasma physics and chemistry related to dry etching

Knowledge of both standard and novel materials for photonic applications along with a deep understanding of advanced nanofabrication processes and integrating them in a coherent manner

Familiarity with Design of Experiments (DOE) methodologies

Ability to learn and adapt to new challenges 

Excellent verbal and written communication and reasoning skills

Ability to prioritise duties, work autonomously, and feed into a larger roadmap

A basic understanding of the fundamentals and operating principles of optics and photonics devices

Minimum Qualifications:

PhD in electronics, physics, nanotechnology, or a similar discipline with 3+ years of relevant postdoc or industry experience

Proficiency in operating and maintaining plasma etch equipment (e.g., ICP-RIE, RIE systems)

Experience with process simulation software for etch modeling

Strong background and hands-on experience with nanofabrication tools and processes (nano-imprint, E-beam, and optical lithography, deposition techniques, etc.) and metrology techniques (AFM, FIB-SEM, profilometry, ellipsometry, etc.)

Strong background in data analysis and visualisation (Matlab, Scientific Python, JMP, etc.)

Preferred Qualifications:

5+ years of relevant postdoc or industry experience with a proven track record of delivering complex programmes with multiple interdependencies and stakeholders

Experience with a range of material characterisation tools and techniques such as FTIR, TGA, GC/MS, EDX, and XRD

We offer a competitive salary range £77,000 - £96,000, which is commensurate with your qualifications and experience and the level of this role. This position is eligible for equity in the form of RSUs. Our compensation philosophy is designed to attract and retain top talent in the industry.This position is eligible for equity in the form of RSUs
