Hardware Engineer, Superconducting

Job Description

Job Title: Hardware Engineer, Quantum Superconducting Digital Electronics. Location: Goleta, California, USA

Your work will support the development of large scale, error corrected quantum computers.

Responsibilities:

• Work with design, fabrication, and measurement teams to validate integrated quantum processors.
• Design and simulate superconductor digital logic circuits, including SFQ and AQFP logic, for qubit control and readout;
• Solve integration challenges related to multi layer cell design, full chip clock synchronization, signal integrity, and flux trapping.
• Develop digital logic systems that enable multiplexed qubit control and readout;
• Use advanced IC design tools, circuit simulation, and electromagnetic modeling to improve performance, signal quality, and thermal management.
• Support fabrication teams by helping define IC design standards suitable for superconducting qubits and cryogenic electronics;
• Contribute to the creation of modular chip stacks that combine qubits and control electronics in cryogenic conditions.

Qualifications:

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Physics, or a related field, or equivalent experience.
• One year of experience in digital circuit design;
• One year of experience working with at least one superconductor logic family such as RSFQ, ERSFQ, RQL, HFQ, or AQFP.

Preferred:

• Master’s or PhD in Electrical Engineering, Computer Engineering, Physics, or a related field.
• Three years of experience designing and simulating superconductor digital logic circuits.
• Experience working 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 circuits.
• Proficiency with CAD tools and electromagnetic simulation tools.
