Job summary

Amazon Web Services (AWS) Center for Quantum Computing is seeking a Senior Applied Scientist to research and design cryogenic control hardware for large-scale quantum processors, focusing on superconducting digital circuits. You will carry designs from concept through simulation, layout, design review, and fabrication handoff, informing organizing investments in control-electronics directions.

The role involves co-design with qubit-device teams, presenting results, and contributing to

Qualifications

PhD or Master's with 7+ years of applied research in a relevant field.
Experience programming in Java, C++, Python or related language.
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.
