Applied Scientist, Quantum Device Packaging & Environment R&D, Device Team, AWS Center Quan

The Amazon Web Services (AWS) Center for Quantum Computing in Pasadena, CA, is hiring an Applied Scientist on the Device Team focused on packaging and environmental R&D for quantum devices. The role requires deep expertise in design, modeling, and testing of packaging and off‑chip environments for microelectronic or quantum devices, with a strong understanding of how packaging and environmental factors impact qubit performance at cryogenic operating conditions.

• Develop packaging and environmental R&D for superconducting quantum devices, spanning design, modeling, and testing of packaging solutions.
• Build electromagnetic and mechanical models to predict and optimize packaging performance, and characterize packaging at cryogenic temperatures.
• Design and develop test standards for characterizing the DC and microwave qubit environment, ensuring rigorous and reproducible assessment of off‑chip environmental contributions to qubit decoherence and loss.
• Automate data collection for environmental test standards and develop automated reporting pipelines to enable efficient, scalable characterization across devices and configurations.
• Collaborate with hardware engineers, PCB designers, and circuit designers to identify and mitigate significant sources of environmental noise and integration uncertainty, driving improvements in qubit performance through off‑chip environment optimization.
• Contribute to multi‑year roadmap planning for packaging and environmental capabilities aligned with CQC objectives, and establish the scientific foundation for this capability area within the Device team.

• Experience in patents or publications at top‑tier peer‑reviewed conferences or journals.
• Experience programming in Java, C++, Python or related language.
• Master’s degree in electrical engineering, computer science, mathematics or physics.
• 3+ years of experience in cryogenic packaging design/testing, microwave engineering, or quantum hardware characterization.
• Familiarity with cryogenic systems and low‑temperature measurement environments.

• Experience using Unix/Linux.
• Experience in professional software development.
• PhD in electrical engineering, computer science, mathematics or physics.
• Hands‑on experience with superconducting quantum device packaging.
• Knowledge of sources of decoherence and loss in superconducting qubit systems related to packaging, off‑chip environments, and interfaces.
• Track record of driving R&D from concept through hardware demonstration.
