Quantum Superconducting Qubit Integration (Member of Technical Staff)

Job Title

Quantum Superconducting Qubit Integration (Member of Technical Staff)

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.

Experience Level

Mid-level. Requires approximately 5+ years of experience in semiconductor process, device, materials, superconducting device, or integration engineering.

Responsibilities

Execute hands-on process and module integration work across device, BEOL wiring, resonator, packaging, and cryogenic characterization domains; use data to drive improvements in performance, yield, variability, and scalability.

• Support integration of superconducting 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, read-out resonators).
• Analyze drivers of process and device performance: defectivity, variability, contamination, interface quality, dielectric loss, flux trapping, and thermalization.
• Design and execute DOEs; analyze inline, physical, electrical, microwave, and cryogenic data to guide integration changes.
• Collaborate cross-functionally with device, process, metrology, packaging, reliability, design enablement, and cryogenic-test teams to meet milestones.
• Translate quantum device requirements into manufacturable flows, design rules, material specifications, characterization plans, and yield-learning actions.
• Document process flows, materials tradeoffs, characterization results, and technical learnings for scalable development and knowledge transfer.

Requirements

Must-have technical skills, experience, and other job requirements.

• Minimum ~5 years relevant experience in semiconductor process, device, materials, superconducting device, or integration engineering.
• 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, problem-solving, debugging, communication, and cross-functional collaboration skills.
• Willingness to travel approximately 10%.

Nice-to-have:

• Experience with superconducting films (Al, Nb, NbN, TiN, Ta) and Josephson Junction process modules (trilayers, shadow evaporation, oxidation control, lift-off, damascene, subtractive patterning).
• Familiarity with microwave engineering for superconducting qubits (resonator Q, dielectric loss, impedance matching, crosstalk, filtering, packaging parasitics).
• Experience with dilution refrigerator measurements, cryogenic probing, S-parameters, resonator extraction, critical-current testing.
• Experience with BEOL integration, low-loss dielectrics, air bridges, TSVs, flip-chip, interposers, or cryogenic packaging.
• Experience with DOE, yield learning, variability modeling, root-cause analysis, SPC, or reliability assessment in R&D or manufacturing.

Education Requirements

Required: BS in Electrical Engineering, Materials Science, Chemical Engineering, Physics, Applied Physics, or a related field. Preferred: MS or PhD in Electrical Engineering, Physics, Applied Physics, Materials Science, or related field.
