This role focuses on developing BEOL process integration for photonic quantum computing hardware, requiring collaboration with teams and foundries, metrology and process innovation.
About Xanadu:
Xanadu’s mission is to build quantum computers that are useful and available to people everywhere.
At Xanadu, we are learners, innovators, researchers, collaborators and problem solvers. We are creating something that has never been built before. What we are doing is extremely hard, the classic moon shot. Few people in their life will be able to be a part of something like this, where if we are successful, the technologies we develop will solve some of the world’s most challenging problems, and literally change the world. And that is something to be excited about!
Your role and responsibilities:As an industry leader in photonic quantum computing, Xanadu takes hardware very seriously! In this role, you will work within the Fabrication Process Engineering team to deliver Xanadu’s photonic quantum computing hardware. With your deep technical expertise and strong experience in back-end-of-line (BEOL) process integration, you will be responsible for developing process integration schemes used to build critical components of Xanadu’s quantum computing hardware.
