About The Position

The AWS Center for Quantum Computing in Pasadena, CA, is looking to hire an Applied Scientist on the Device Team, focused on integration R&D for superconducting quantum processors. 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, fabrication, and characterization of superconducting quantum devices, with a strong understanding of how materials, process integration, and device architecture impact qubit coherence and performance. Candidates with a track record of original scientific contributions in superconducting qubit coherence, thin film materials, or Josephson junction engineering 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 integration R&D from concept through hardware demonstration and stay abreast of advances in superconducting quantum hardware.

Requirements

• 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 or above in engineering, physics, or equivalent
• Familiarity with cryogenic systems and low-temperature measurement environments
• 2+ years of hands-on experience with superconducting quantum devices (resonators, transmons, or related circuits)

Nice To Haves

• Experience using Unix/Linux
• Experience in professional software development
• Experience collaborating with cross-functional teams
• Experience with flip-chip or 3D integrated superconducting devices
• Familiarity with tantalum or other refractory metal-based superconducting circuits
• Experience with loss characterization and SPR analysis in CPW or lumped element resonator geometries
• Knowledge of Josephson junction engineering including oxidation control, underjunction processing, and junction aging
• Experience with cat qubit or bosonic qubit architectures
• Track record of driving R&D from concept through hardware demonstration

Responsibilities

• Work at the unit cell level to integrate and evaluate new fabrication process modules and device design changes for superconducting quantum processors.
• Design and execute experiments to assess performance impacts.
• Investigate unexpected results through rigorous analysis and follow-on experiments.
• Leverage electromagnetic and circuit-level simulations to interpret findings and connect observations to underlying physical mechanisms.
• Coordinate with production and cross-functional teams on engineering lots, short-loop experiments, and prototyping runs to build the scientific foundation for next-generation processor integration at CQC.

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
• sign-on payments
• restricted stock units (RSUs)
