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

The Amazon Web Services (AWS) Center for Quantum Computing in Pasadena, CA, is looking to hire an Applied Scientist on the Device Team, focused on packaging and environmental R&D for quantum devices. You will join a multi-disciplinary team of theoretical and experimental physicists, materials scientists, and hardware and software engineers working at the forefront of quantum computing. You should have deep expertise in the 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.

Candidates with a track record of original scientific contributions in packaging, microwave engineering, or quantum cryogenic hardware will be preferred. We are looking for candidates with strong scientific and engineering principles, resourcefulness and a bias for action, superior problem solving, and excellent communication skills. Working effectively within a team environment is essential. As an applied scientist at CQC, you will be expected to drive packaging and environmental R&D from concept through hardware demonstration and stay abreast of advances in quantum hardware packaging and cryogenic measurement science.

• Design, model, and test packaging solutions for superconducting quantum devices, building electromagnetic and mechanical models to predict and optimize packaging performance and characterizing 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 the most 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 help 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 languages.
• 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.
