Process Integration Engineer (Remote)

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. 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 photonics fabrication process development and process integration, you will be responsible for developing process integration schemes used to build critical components of Xanadu’s quantum computing hardware.

• Own the definition, development and implementation of process integration flows used to build photonic quantum computing hardware that meets strict performance specifications
• Collaborate with internal and external photonics process engineers to refine fabrication procedures for ultra-low loss photonic quantum computing chips
• Work with Xanadu’s foundry partners to continuously improve integration schemes and balance competing fabrication requirements
• Define and execute metrology and failure analysis plans to identify and mitigate failure modes and assess results of process integration experiments
• Deliver integrated quantum photonics chips and circuits containing multiple active and passive components
• Coordinate between several internal component teams to ensure all hardware requirements are satisfied in delivered chips and circuits
• Innovate in the space of photonic process development and process integration, especially with respect to ultra-low loss components
• Stay abreast of new developments in the fields of photonics fabrication process development and integration
