Overview In this role you will engineer cryogenic control hardware for scalable superconducting qubit systems, driving the design from concept through fabrication handoff. You'll model and simulate superconducting logic, assess system-level trade-offs, and align control electronics with qubit devices to enable large-scale quantum processors. You'll work with cross-functional teams to shape control architectures and publish results in peer venues, contributing to AWS's quantum computing ambitions.

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
Key requirements- 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
- Collaborative mindset
- Strong communication and presentation skills
- Cross-functional teamwork with hardware and quantum-device colleagues
- Superconducting digital circuit design (RSFQ/ERSFQ, SJQP-related)
- Josephson-junction circuit modeling and simulation
- Cryogenic electronics design and validation
