Process Integration Engineer - Heterogeneous Integration Development - Santa Clara, CA

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!

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 experience developing heterogeneous integration processes for integrated photonics, you will be responsible for developing and optimizing fabrication and integration processes used to build critical components of Xanadu’s quantum computing hardware.
