Process Integration Engineer - BEOL

Xanadu is focused on building quantum computers that are useful and accessible to everyone. They are seeking a Process Integration Engineer to work within the Fabrication Process Engineering team, responsible for developing and implementing BEOL process integration flows for photonic quantum computing hardware.

Responsibilities:

• Own the definition, development and implementation of BEOL 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 BEOL fabrication processes for photonic quantum computing chips
• Coordinate with FEOL process integration engineers and Packaging to ensure BEOL processes are compatible with all hardware and systems requirements
• 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
• Innovate in the space of photonic process development and process integration, especially with respect to BEOL processes for integrated photonics
• Stay abreast of new developments in the fields of photonics fabrication process development and integration

Requirements:

• PhD in physics, materials science, photonics or related field
• ≥ 5 years of experience in photonics and/or semiconductor chip fabrication, with an emphasis on BEOL process integration and process development
