Hardware Engineer, Quantum Superconducting Digital Electronics

GoogleGoleta, CA, USA

Minimum qualifications:

  • Bachelor’s degree in Electrical Engineering, Computer Engineering, Physics, a related field, or equivalent practical experience.
  • 1 year of experience with digital circuit design.
  • 1 year of experience with one or more superconductor logic family (e.g., RSFQ, ERSFQ, RQL, HFQ, AQFP, and other related families).

Preferred qualifications:

  • Master's or PhD degree in Electrical Engineering, Computer Engineering, Physics, or a related field.
  • 3 years of research/industry experience in the design and simulation of superconductor digital logic circuits.
  • Experience with superconducting qubits.
  • Experience with full digital design flow including RTL, synthesis, verification, timing closure, place-and-route, and post-fabrication validation.
  • Experience with low-temperature measurements of superconductor digital logic circuits.
  • Proficiency with computer-aided design tools and electromagnetic simulation tools.

About the job

Be part of a team that pushes boundaries, developing custom silicon solutions that power the future of Google's direct-to-consumer products. You'll contribute to the innovation behind products loved by millions worldwide. Your expertise will shape the next generation of hardware experiences, delivering unparalleled performance, efficiency, and integration.

As a Hardware Engineer, your primary focus will be designing and simulating superconductor digital logic circuits (such as single flux quantum (SFQ) logic and adiabatic quantum flux parametron (AQFP) logic) for qubit control and readout. You will engage in co-design loops with qubit designers and other hardware engineers, utilizing advanced IC design tools, numerical circuit simulation techniques and 3D electromagnetic modeling to optimize signal integrity, minimize cross-talk, manage thermal budgets, and aim performance metrics required for coherent control of qubits. You will also interface with fabrication engineers to help define and establish robust IC design standards that are compatible for both the sensitive superconducting qubits and the co-located cryogenic control electronics. This work is critical to building a fully integrated, modular chip stack that combines superconducting qubits with their control electronics directly within the cryogenic environment, accelerating the path toward large-scale, error-corrected quantum computer.

The full potential of quantum computing will be unlocked with a large-scale computer capable of complex, error-corrected computations. Google Quantum AI's mission is to build this computer and unlock solutions to classically intractable problems. Our roadmap is focused on advancing the capabilities of quantum computing and enabling meaningful applications.

The US base salary range for this full-time position is $126,000-$181,000 + bonus + equity + benefits. Our salary ranges are determined by role, level, and location. Within the range, individual pay is determined by work location and additional factors, including job-related skills, experience, and relevant education or training. Your recruiter can share more about the specific salary range for your preferred location during the hiring process.

Responsibilities

  • Collaborate with teams focused on design, fabrication, and measurement to validate fully integrated quantum processors.
  • Design and simulate superconductor digital logic circuits (such as single flux quantum (SFQ) logic, adiabatic quantum flux parametron (AQFP) logic, and other emerging superconductor logic families) for generating waveforms tailored to qubit control and readout.
  • Address challenges in the large-scale integration of superconductor digital electronics such as multi-layer cell design, full-chip clock synchronization, flux trapping, and signal integrity.
  • Develop superconductor digital logic systems enabling multiplexed qubit control and readout.
