About the role

This role involves researching and designing cryogenic control hardware for large-scale quantum processors, with an emphasis on superconducting digital circuits. You will design and model superconducting digital logic (e.g., single-flux-quantum-family circuits) and related cryogenic electronics.

What you'll do

• Design and simulate superconducting digital circuits and cryogenic control/readout electronics for scalable qubit control.
• Develop and validate Josephson-junction circuit models, timing and margin analyses, and verification methodology for superconducting digital designs.
• Quantify system-level trade-offs across candidate control architectures, and communicate recommendations.
• Co-design control interfaces with qubit-device colleagues for integrated system development.
• Deliver design artifacts through the organization's design-request and design-review processes, including tapeout-ready layouts and verification reports.
• Present results internally and publish in peer-reviewed venues where appropriate.

What you'll need

• Experience researching and designing cryogenic control hardware for large-scale quantum processors.
• Emphasis on superconducting digital circuits.
• Ability to design and model superconducting digital logic (e.g., single-flux-quantum-family circuits) and related cryogenic electronics.
• Experience evaluating designs against wiring, power, and thermal budgets of a scaled system.
• Ability to carry designs from concept through simulation, layout, design review, and fabrication handoff.
