Quantum Superconducting Qubit Integration

Job Title

Quantum Superconducting Qubit Integration

Role Summary

Technical contributor within GF Labs / Technology Development focused on enabling scalable superconducting quantum-computing hardware. The role supports integration of superconducting materials, Josephson Junction devices, low-loss wiring, resonators, cryogenic read-out structures, and manufacturable process flows.

Emphasis on hands-on execution, data-driven problem solving, and cross-functional collaboration to improve device performance, yield, variability, and scalability.

Experience Level

Mid-level. The role expects demonstrated experience in semiconductor process, device, materials, superconducting device, or integration engineering (guidance: 5+ years).

Responsibilities

Core responsibilities include:

• Integrate superconducting qubit hardware: wiring, Josephson Junctions, resonators, BEOL modules, cryogenic interfaces, and packaging.
• Develop and execute process integration flows for superconducting materials, junction formation, patterning, dielectric interfaces, and module interactions.
• Improve low-loss superconducting interconnects and microwave structures for cryogenic operation (ground planes, vias, crossovers, air bridges, feedlines, filters, resonators).
• Analyze process and device performance drivers: defectivity, variability, contamination, interface quality, dielectric loss, flux trapping, and thermalization.
• Design and run DOEs; analyze inline, physical, electrical, microwave, and cryogenic data to guide integration improvements.
• Collaborate with device, process, metrology, packaging, reliability, design enablement, and cryogenic-test teams to deliver integration milestones.
• Translate superconducting quantum requirements into manufacturable flows, design rules, material specifications, and characterization plans.
• Document process flows, materials tradeoffs, characterization results, and technical learnings for scalable development and knowledge transfer.

Requirements

Must-have technical skills and experience:

• Significant hands-on experience with superconducting wiring, superconducting materials, and cryogenic device or quantum-hardware integration.
• Experience with Josephson Junction fabrication, integration, testing, or characterization.
• Experience with cryogenic characterization of superconducting devices, resonators, interconnects, or related structures.
• Experience designing, integrating, or characterizing superconducting circuits, resonators, or microwave structures for qubit control/read-out.
• Strong data analysis, debugging, problem-solving, written and verbal communication, and cross-functional collaboration skills.
• Familiarity with executing DOEs, analyzing electrical/microwave/cryogenic datasets, and using results to drive process improvements.
• Ability to document technical work for knowledge transfer and scale-up to manufacturable flows.
• Willingness to travel approximately 10%.

Education Requirements

Bachelor of Science (BS) in Electrical Engineering, Materials Science, Chemical Engineering, Physics, Applied Physics, or a related field is required. Master of Science (MS) or PhD in those fields is preferred.
