D-Wave is seeking a Superconducting Integrated Circuit (IC) Designer to join our IC Design team, which builds the chips at the heart of our quantum computers. These chips are some of the most complex superconducting integrated circuits ever fabricated and require a sophisticated, customized electronic design automation (EDA) toolchain.

• Modeling, designing, and improving performance of devices on a superconducting quantum processor. These devices include Josephson junctions, qubits, SQUIDs (superconducting quantum interference devices), SFQ (single flux quantum) gates, QFPs (quantum flux parametrons), resonators, and many others.
• Using the EDA toolchain, identifying shortcomings, and conceiving and developing improvements.
• Topological and parametric design of a variety of novel devices and/or device enhancements to improve processor performance or enable new capabilities.
• Understanding the impact of the processor’s environment, including packaging, I/O, electronics and cryogenic elements, and developing approaches to mitigate it.

In this intermediate-seniority role, you will receive frequent mentorship and feedback from colleagues. Previous experience in quantum circuits or superconducting circuits is not required.

The IC Design team is part of the PD group, which leads the advancement of our quantum computing hardware. Your work will directly impact our quantum processor architecture and its capabilities. If you’re passionate about design, complex systems, and collaborating across disciplines, we want to hear from you.
