Process Integration Engineer - Heterogeneous Integration Development - Santa Clara, CA

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. What we are doing is extremely hard, the classic moon shot. 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 experience developing heterogeneous integration processes for integrated photonics, you will be responsible for developing and optimizing fabrication and integration processes used to build critical components of Xanadu’s quantum computing hardware.

You will:

Design and execute process improvement experiments for heterogeneous integration of photonic components, including defining process splits, gathering and analyzing inline data, etc.

Work with external partners to execute process development and optimization experiments for heterogeneous integration processes, including micro-transfer printing (µTP), die-to-wafer bonding, wafer-to-wafer bonding, or similar

Define and execute metrology and failure analysis plans to identify and mitigate failure modes and assess results of process optimization experiments

Regularly visit and coordinate with Xanadu’s heterogeneous integration industrial partners

Continuously evaluate the need for tool purchases related to heterogeneous integration processes and perform best-of-breed evaluations to inform any tool purchase decisions

Collaborate with internal and external photonics process engineers, process integration engineers and photonics design engineers, including at Xanadu’s industrial partners

Challenge the state-of-the-art in key performance metrics associated with heterogeneous integration for integrated photonics components

Stay abreast of new developments in the field of heterogeneous integration for integrated photonics and rapidly implement new learnings and discoveries

Be available for travel as required (expected ≤ 20% travel time)

Basic qualifications and experience:

PhD in physics, materials science, electrical engineering or related field

Experience with heterogeneous integration processes for integrated photonics and/or semiconductor applications, including some subset of µTP, die-to-wafer bonding, wafer-to-wafer bonding, or similar

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, photoluminescence

Familiarity with functional epitaxial and crystalline materials for photonics, including III-Vs, lithium niobate, etc.

Experience with data analysis and related software, such as Python, JMP, MATLAB, etc.

Basic familiarity with passive and active photonic components, such as waveguides, modulators, switches, beamsplitters, resonators, MZIs, etc.

Strong critical thinking skills

Demonstrated ability to tackle challenging problems and develop innovative solutions
