Senior Integration & Yield Engineer (Superconducting Quantum Circuits)

Location: Aubervilliers, France; hybrid workplace. Flexible remote work is available for up to 40% of the month.

Company

Alice & Bob is developing a universal, fault-tolerant quantum computer based on superconducting Schrödinger cat qubits with autonomous quantum error correction.

What you will do

• Own yield monitoring across fabrication flows by defining metrics, building automated wafer-report dashboards, and providing visibility into fab performance.
• Lead root cause analysis of systematic and random yield detractors and perform statistical analysis using Python and JMP.
• Define and maintain process-of-reference integration flows, design-for-manufacturability guidelines, fabrication documentation, and process KPIs.
• Maintain design-to-fabrication interfaces, including LUTs linking design parameters to Josephson junction fabrication and DRM extensions.
• Translate device designs into fabrication-ready wafer layouts and develop Python tools to automate the design-to-wafer pipeline.
• Coordinate failure investigations at room and cryogenic temperatures using electrical test data, inline metrology, SEM, and AFM, and lead corrective and preventive actions.

Requirements

• Master’s degree or Ph.D. in Physics, Materials Science, or a related field.
• At least 3 years of hands-on experience in semiconductor or superconducting circuit nanofabrication or process integration.
• Expertise in yield engineering, SPC, DOE, and statistical analysis tools.
• Proficiency in Python scripting to adapt and extend tools connecting design and fabrication workflows.
• Command of root cause analysis methodologies, including 5 Whys, FMEA, and Ishikawa.
• Strong problem-solving skills, excellent communication skills, and the ability to work effectively in a cross-disciplinary environment.

Nice to have

• Experience in the fabrication or characterization of superconducting circuits, or in cryogenic testing.
