Xanadu is building quantum computers using photonic technology with the mission to make quantum computing useful and accessible globally. This is a senior engineering role within the Fabrication Process Engineering team, focused on developing and optimizing fabrication processes for integrated photonic devices based on electro-optic materials, particularly thin-film lithium niobate (TFLN).
You will own the development and optimization of process modules used to build critical components of Xanadu's quantum computing hardware. Key responsibilities include:
- Develop and optimize fabrication process modules for integrated photonic devices from crystalline electro-optic materials
- Independently own and direct wafer lots processed at Xanadu's foundry partners
- Design and execute fabrication process improvement experiments, including defining fabrication splits and analyzing inline data
- Define and execute metrology and failure analysis plans to identify and mitigate failure modes
- Collaborate with internal and external photonics process engineers, process integration engineers, and photonics design engineers
- Challenge the state-of-the-art in key performance metrics for integrated photonics fabrication
- Stay current with new developments in photonics fabrication process development
This role requires deep technical expertise in photonic device fabrication and a track record of solving complex engineering challenges. You will work at the intersection of quantum computing hardware and advanced photonics manufacturing, contributing to technology that could solve some of the world's most challenging problems.
Travel of approximately 20% or less is required.
REQUIREMENTS:
