Alice & Bob is hiring a Test and Characterization Engineer — a full-time, based in Aubervilliers role. Apply directly on Alice & Bob's careers page below.
Test and Characterization Engineer H/F
Team: Nanofabrication Backend
Location: Aubervilliers
Commitment: CDI
Workplace Type: onsite
Alice&Bob is developing a quantum computer based on cat qubits. While initially running nanofabrication processes in academic cleanrooms, Alice&Bob now has its own prototyping cleanroom in Ile de France. This facility will allow to:
- Speed up the design iteration cycle, by reducing the leadtime of chip fabrication
- Improve the capability of Alice&Bob nanofabrication processes (improving performance and mastering 3D integration)
As part of the Quantum Hardware department, the “Nanofabrication Backend” team will play a pivotal role in operating and developing the “backend of line” used for manufacturing Alice&Bob Quantum Processor. Technically, this encompasses:
- Room temperature electrical testing
- Dicing
- Optical inspection
- Wirebonding of chips inside sample holders
The team is in charge of:
- operating the tools for the regular delivery of test chips
- developing/improving new processes (for better quality/leadtime/chip selection…)
- overseeing its own tools (daily check of the tools, ensuring maintenance schedules are followed, 1 level of troubleshooting)
- selection, installation and qualification of new tools
Responsabilities
- Develop and optimize superconducting qubit testing methods at room and cryogenic temperatures, providing fast feedback to nanofabrication processes and ensuring efficient sorting of chips.
- Collaborate with design and process integration teams to define and evaluate test structures that improve wafer- and chip-level performance.
- Ensure accuracy and reliability of equipment metrology, data acquisition systems and inspection equipment.
- Contribute to the identification, procurement, and validation of new test and metrology equipment for the backend nanofabrication line.
- Implement continuous improvement plans to enhance testing efficiency, reliability, and throughput.
- Perform device testing at room and cryogenic temperatures, ensuring accurate and reproducible results.
- Participate in failure analysis and root cause investigations, helping to close the loop between design, fabrication, and performance.
About the Role
Requirements
- Master’s degree or Ph.D. in Physics, Electrical Engineering, Materials Science, or a related field.
- 3+ years of hands-on experience with device testing, electrical measurements, or semiconductor/metrology equipment.
- Familiarity with superconducting devices or cryogenic measurements is a strong plus.
- Proficiency with data acquisition systems, lab instrumentation, and analysis tools (e.g., LabVIEW, Python, MATLAB, JMP).
- Strong problem-solving mindset, analytical rigor, and attention to detail.
- Ability to work collaboratively in a fast-paced, cross-disciplinary environment.
- Languages: Proficiency in French, professional English
- Aubervilliers
