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're a diverse team of 140+ brilliant minds from over 20 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!
Alice & Bob is developing a quantum computer based on cat qubits. After initially running nanofabrication processes in academic cleanrooms, the company is now taking a major step forward by building its own prototyping cleanroom in Île-de-France (construction underway, start of operation planned for Q2 2026).
This facility will:
Accelerate design iteration cycles by reducing chip fabrication lead times
Strengthen Alice & Bob’s nanofabrication capabilities, enabling higher performance devices and improved mastery of 3D integration
This position is part of the Foundries & Process Integration (FPI) team within the Quantum Hardware Department.
The FPI team plays a key role along two main axes:
Supporting internal nanofabrication activities carried out by the Nanofabrication Front-End and Back-End teams through:
- Coordination and operation of process data analysis (test structures definition, trend analysis, process data management via MES)
- Development of process and device performance models (e.g., yield projection) to guide design decisions
- Leadership of transversal failure analysis across fabrication teams
Driving external foundry collaborations to ensure scalable chip supply and prepare the transition toward large-scale quantum processors
About the Role
We are looking for a hands-on MES Integration Engineer to deploy, configure, and operate a commercial Manufacturing Execution System (MES) supporting our quantum chip fabrication and packaging activities.
The role focuses on translating complex superconducting device process flows into MES logic, integrating fabrication, metrology, and test equipment, enabling full data traceability, and supporting process engineers and operators in an R&D and prototyping environment.
The MES solution and provider have already been selected. This role will act as the technical owner of the MES within Alice & Bob’s chip manufacturing and characterization ecosystem.
Responsibilities
MES Deployment & Process Configuration
·Deploy, configure, and customize a commercial MES solution tailored to superconducting quantum device fabrication, packaging and characterization.
·Translate complex fabrication flows—including but not limited to thin-film deposition, lithography, etching, Josephson junction fabrication, packaging, and test preparation—into MES routings, workflows, and data models.
·Configure process steps, rework loops, holds, experimental splits, and engineering runs consistent with an R&D / prototyping cleanroom.
·Maintain and evolve MES configurations as processes, stacks, and design rules change.
Equipment Integration, Maintenance & Data Acquisition
·Design and implement custom APIs and interfaces to connect fabrication, metrology, packaging and characterization equipment to the MES.
·Integrate equipment that does not support SECS/GEM, using alternative approaches (file-based interfaces, scripts, APIs).
·Configure the MES to extract, parse, and store parameters from equipment log files (process tools, metrology systems, test benches).
·Configure MES functionalities for preventive and frequent maintenance tracking, including:
oMaintenance scheduling
oUsage-based counters
oAlarm and notification management
·Ensure robust data traceability at the wafer, chip, and lot levels.
Manufacturing Data, Analysis & Dashboards
·Build and maintain analysis dashboards for process and equipment monitoring, yield, variability, and engineering investigations.
·Correlate data across multiple sources (MES, equipment logs, metrology databases, electrical and cryogenic test databases).
·Support process integration, yield analysis, and failure analysis through structured, reliable, and accessible data.
User Training & Support
·Train MES users across process integration, nanofabrication, test, and operations teams.
·Provide day-to-day MES support, troubleshooting, and documentation.
·Act as the main technical interface with the MES vendor for configuration changes, upgrades, and issue resolution.
