• Develop and optimize process modules for integrated photonic devices made from crystalline electro-optic materials, such as thin-film lithium niobate.

• Independently manage and direct wafer lots processed at Xanadu’s foundry partners.

• Design and conduct fabrication process improvement experiments, including defining fabrication splits and collecting and analyzing inline data.

• Develop and execute metrology and failure analysis plans to identify and mitigate failure modes and evaluate process optimization results.

• Collaborate with internal and external photonics process engineers, process integration engineers, and photonics design engineers, including teams at foundry partners.

• Improve key performance metrics for integrated photonics fabrication beyond current industry standards;

• Monitor new developments in photonics fabrication process development and implement relevant discoveries.

Qualifications:

• PhD in physics, materials science, electrical engineering, or a related field.

• Experience with integrated photonics, including familiarity with passive and active photonic components such as waveguides, modulators, switches, beamsplitters, resonators, and Mach-Zehnder interferometers (MZIs).

• Hands-on experience developing fabrication processes for thin-film lithium niobate (TFLN) circuits.

• Familiarity with standard semiconductor and photonics metrology and failure analysis techniques, including at least two of the following: SEM, TEM, AFM, ellipsometry, XRR/XRD, SIMS, Raman spectroscopy, and photoluminescence.

• Experience with data analysis software and tools such as Python, GitHub, JMP, or MATLAB;

• Strong critical thinking skills and the ability to solve challenging problems with innovative solutions.

• Excellent communication skills and a strong sense of teamwork.

• Availability to travel, with travel expected to be 20% or less.

Preferred:

• Five or more years of experience in integrated photonics fabrication and fabrication process development using electro-optic materials, such as thin-film lithium niobate.

• Demonstrated success in achieving low optical loss in integrated photonic components through fabrication process development.

• Experience designing photonic components, including device simulation and layout.

• Experience developing hardware for photonic quantum computing.

• Proficiency in Mandarin.

Compensation and benefits:

• Annual base salary of CAD $120,000 to $160,000, determined by location, experience, and internal benchmarks.

• Eligible for equity and employee benefits.
