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. 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 part of the Hardware Team, you will work with our established team of physicists and engineers to support existing efforts to improve the performance of photon number resolving (PNR) cryogenic detectors. In this role you will contribute your experience spanning cryogenic detectors, superconducting device measurement, clean room fabrication and data analysis all aimed at optimizing our transition edge sensors (TES). You will join the Low Temperature Devices team dedicated to the systems-level design and deployment of large-scale arrays of optical TES PNR detectors and their integration within the full Xanadu hardware stack. A key part of the role will involve travel within Canada for clean room development in partner facilities. In addition, you will interface with internal stakeholders to understand the critical requirements throughout the system.
Required Qualifications and Experience:
- PhD with 4+ years additional experience (postdoc or industry) in Physics, Engineering, Experimental Sciences, or related relevant discipline.
- Experience working with cryogenic detectors or their applications, for example in CMB, TES, MKID or SNSPDs.
- Experienced in the operation of clean room tools including photolithography, deposition (PVD, CVD), wet & plasma etching (RIE, ICP), and characterization (AFM, ellipsometry).
- Experience in developing cleanroom recipes and keep detailed documentation
- Understanding the physics of superconductivity and superconducting devices and circuits.
- Experience with precision measurements of small nanovolt/nanoamp level signals.
- Experience with analog testing equipment (VNA, spectrum analyzer, SMU etc)
- Experience writing Python code.
- Experience working in a collaborative team-based development environment.
- Ability to operate autonomously in a fast-paced environment and manage multiple competing priorities.
Preferred Knowledge and Experience:
- Knowledge of optical thin film stack metrology, characterization and optimization
- Experienced in the independent operation and requirements of milli-Kelvin cryostats, specifically dilution refrigerators.
- Knowledge of relevant areas of photonics.
- Experience with large data set analysis and statistical reporting.
