About the Role

Advance cutting-edge Superconducting Nanowire Single Photon Detectors (SNSPDs) for Xanadu's quantum architecture by developing record-breaking photon-number-resolving detectors with ultra-high system detection efficiency, short reset times, and scalability. This role involves designing and enhancing the performance and scalability of the SNSPD platform, taking full ownership from concept through validation and deployment.

Responsibilities

  • Design and optimize superconducting analog components and circuits for integration into SNSPD-based systems.
  • Contribute to circuit architectures enabling scalable multiplexing and readout of large-scale SNSPD arrays and on-chip integration.
  • Drive improvements in key SNSPD performance metrics relevant to Xanadu’s system architecture.
  • Translate device designs into tapeout-ready GDS layouts for fabrication with external foundries.
  • Support cryogenic validation of device and circuit performance, including analysis of measurement data to inform design iterations.
  • Collaborate with internal and external process integration engineers, packaging engineers and technicians, including at Xanadu’s foundry partners.

Requirements

  • PhD in Physics, Electrical/Mechanical Engineering, or a closely related field, with at least 2 years of postdoctoral or industry experience.
  • Circuit design and simulation using SPICE models, including relevant parasitic components.
  • Strong understanding of superconducting device physics and single-photon detection mechanisms.
  • Familiarity with standard fabrication techniques and their influences on design.
  • Experience using Python for component design, simulation, GDS layout, and data analysis.
  • Ability to work independently and collaboratively in a fast-paced, cross-disciplinary environment.
  • Strong attention to detail and a rigorous, data-driven approach to problem solving.
  • Excellent written and verbal communication skills.
