Laboratory Technician Backend Process

Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.

The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously

We are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.

Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future

Alice&Bob is developing a quantum computer based on cat qubits. While initially running nanofabrication processes in academic cleanrooms, Alice&Bob is stepping up by building its own prototyping cleanroom in Ile de France (construction started, start of operation beginning 2026). 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, 1st level of troubleshooting)

selection, installation and qualification of new tools

As **nanofabrication backend technician**, you will play a key role in bringing into reality the QPU designs imagined by the company. Your technicity and attention to the details will directly contribute to our technical excellence and speed of execution, shaping the future of quantum computing. For this position, we are seeking a technician with a background in **backend / electrical tests in semiconductor/superconductor processes** to join our talented team.

**Responsibility**:

- **Execute the day-to-day operations, which include**:

- Dicing
- Optical inspection
- Wirebonding of chips inside sample holders
- Assembly of sample holders
- ** Process development**: Contribute to the R&D tests for improving the process/recipes, keeping up with the latest technological progress.
- ** Tools responsibility**: Be responsible for one or several tools of the team (following preventive maintenance plan and managing corrective/troubleshooting when necessary). This includes the responsibility of training new users on the tool if necessary.
- ** Continuous Improvement**: Contribute to continuous improvement projects in the team (troubleshooting, A3, failure analysis )
- ** Documentation & Reporting**: Ensure standard operation procedures stay up-to-date, and document the operations and results obtained.
- ** Contribute to specific projects of the department** (examples : assembly and start of operation of new cryostats, hook up and qualification of new tools )

**Requirements**:

- ** Educational Background**: BSc in a related field (DUT « Electronique », « Mesures physiques », « Genie industriel et maintenance » or equivalent)
- ** Experience**: Mini 3 years of experience as laboratory or operation technician in an industrial or R&D environment. Experience in a semiconductor, electronic, or cryogenic environment is considered as a plus.
- Experience in one part of our backend process (wirebonding, dicing, electrical testing) is considered as a plus.
- Nice to have : Rigorous, strong adherence to processes, Autonomous, Prone to continuous improvement, ability to work as part of a multi-disciplinary team without friction, ability to troubleshoot and solve hardware issues
- English = intermediate (required to communicate with Alice&Bob team, and suppliers)
