Your role and responsibilities: In this role, you will contribute your expertise in superconductors and analog components to advance our cutting-edge Superconducting Nanowire Single Photon Detectors (SNSPDs) required for our quantum architecture. This will involve challenging the state-of-the-art with novel approaches to make world-leading devices. As a member of the Low Temperature Devices Team, your primary responsibility will be the development of record-breaking photon-number-resolving detectors with ultra-high system detection efficiency, short reset times, and scalability to large-scale deployment. With your deep technical expertise and experience in superconducting component and circuit design, you will play a critical role in designing and enhancing the performance and scalability of our SNSPD platform. This role requires significant experience with on-chip superconductor design, as well as the ability to work effectively across disciplines in a fast-paced environment to integrate into for large-scale quantum system designs. You will take full ownership of their development, from concept through validation and deployment within large-scale detector arrays. • Design and optimize superconducting analog components and circuits (e.g., inductors, transmission lines, and detector interfaces) 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 (e.g., system detection efficiency, reset time, yield, and scalability) 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 Basic qualifications and experience: • 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 Preferred qualifications and experience: • Simulation experience for device-level modeling (e.g., COMSOL, pyTDGL) • Deep proficiency with superconducting theory including TDGL • Proficient writing Python code • Familiarity with statistical process control and yield optimization in fabrication workflows • Experience with large-scale detector arrays or multiplexed readout architectures This is for a new position. Your base salary will be determined based on your location, experience, and internal benchmarks. The base salary range is 150,000 - 200,000 CAD. You will also be eligible for equity and benefits.
