4h•$150,000 - $200,000

About The Position

Xanadu is hiring a Sr. Process Integration Engineer to join its Fabrication Process Engineering team and help deliver photonic quantum computing hardware. The role focuses on developing and optimizing fabrication processes for integrated photonic devices based on crystalline electro-optic materials, such as thin-film lithium niobate. The engineer will work with the Design team to improve optical-component yield and develop complex device stacks, including low-loss edge couplers, electro-optic modulators, and room-temperature photodiodes. The position also involves owning wafer lots at foundry partners, conducting process-improvement experiments, establishing metrology and failure-analysis plans, collaborating with internal and external engineering teams, and applying new developments in photonics fabrication.

Requirements

PhD in physics, materials science, electrical engineering, or a related field.
At least 10 years of experience working in a foundry environment for semiconductor and/or integrated photonics products.
Experience with the full product-development cycle, from R&D through volume ramping.
Experience coordinating with and managing external partners, including major semiconductor and photonics foundries.
Experience developing semiconductor fabrication processes, including common process modules and optimization pathways.
Demonstrated track record of achieving low loss in integrated photonic components through fabrication process development.
Familiarity with standard semiconductor and photonics metrology and failure-analysis techniques, including at least two of SEM, TEM, AFM, ellipsometry, XRR/XRD, SIMS, Raman spectroscopy, and photoluminescence.
Basic familiarity with passive and active photonic components, such as waveguides, modulators, switches, beamsplitters, resonators, and MZIs.
Strong critical-thinking skills.
Demonstrated ability to tackle challenging problems and develop innovative solutions.
Excellent communication skills and a strong sense of teamwork.
Availability to travel, with expected travel of 20% or less.

Nice To Haves

At least 5 years of experience with integrated photonics fabrication and fabrication process development using electro-optic materials, such as thin-film lithium niobate.
Experience with integrated photonics.

Experience procuring processing and/or measurement tools, including best-of-breed evaluations, acceptance testing, tool installation, and process qualification.
Experience with data analysis and related software, such as Python, GitHub, JMP, or MATLAB.
Experience working in fabless companies.
Proficiency in Mandarin.

Responsibilities

Develop and optimize process modules used to build integrated photonic devices from crystalline electro-optic materials, such as thin-film lithium niobate.
Work with the Design team to improve optical-component yield and build complex stacks combining components such as low-loss edge couplers, electro-optic modulators, and room-temperature photodiodes.
Independently own and direct wafer lots processed at Xanadu’s foundry partners.
Design and execute fabrication process-improvement experiments, including defining fabrication splits and gathering and analyzing inline data.
Define and execute metrology and failure-analysis plans to identify and mitigate failure modes and assess process-optimization results.
Collaborate with internal and external photonics process engineers, process integration engineers, and photonics design engineers, including teams at Xanadu’s foundry partners.
Advance state-of-the-art performance metrics associated with integrated photonics fabrication.
Monitor developments in photonics fabrication process development and implement new learnings and discoveries.
