Senior Quantum Control Scientist - Cryogenic Electronics

Amazon Science; San Francisco (CA); On-site; USD 192,000 - 260,000; Full time

Job summary

Amazon Science seeks a Senior Applied Scientist to research and design cryogenic control hardware for large-scale quantum processors, emphasizing superconducting digital circuits and qubit readout. You will model, simulate, and co-design control electronics with qubit devices across multiple cryogenic stages.

Responsibilities include delivering tapeout-ready layouts, verification reports, and presenting results; and publishing in peer-reviewed venues when appropriate.

Qualifications

• PhD, or Master's degree and 7+ years of applied research experience.
• Experience programming in Java, C++, Python or related language.
• Experience in patents or publications at top-tier peer-reviewed conferences or journals.
• Experience with circuit design and simulation.
• Familiarity with superconducting qubit control and readout – pulse generation, multiplexed readout, feedback latency requirements.
• Experience designing superconducting digital circuits (RSFQ/ERSFQ, adiabatic quantum phase parametron, or related single-flux-quantum logic families), including Josephson-junction circuit simulation and margin analysis.
• Experience with EDA flows for custom circuit design – schematic capture, layout, physical verification, and working against a process design kit.

Responsibilities

• 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 – wiring count, power dissipation at each cryogenic stage, latency, footprint – across candidate control architectures, and communicate recommendations
• Co-design control interfaces with qubit-device colleagues so control electronics and quantum devices are developed as one system
• Deliver design artifacts through the organization's design-request and design-review processes, including tapeout-ready layouts and verification reports
• Present results internally and, where appropriate, publish in peer-reviewed venues
