Description de posteAlice & 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 250+ brilliant minds from over 35 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. As part of the Quantum Hardware and Infrastructure department, the Hardware Platform Operation (HPO) team is in charge of operating the cryoplatform. This platform represents a major investment and asset of the company: HPO team is focused at 100% on operational excellence and quality, to ensure the highest availability rate.
Responsibilities
HPO team is in charge of operating the cool down/warm up + modifications of cabling (inside the cryostat and instrumentation racks), according to the requests of the users. The HPO team is the main entry point from the users.
The maintenance in operational conditions of the cryostats
The maintenance in operational conditions of the control electronics (racks)
This includes routine V&V on instrumentation devices
First level of troubleshooting
Monitoring of environmental conditions (vibrations, temperature…)
Assembly of new systems
About The Role As the Leader of the HPO Team, you play a pivotal role in bringing into reality the QPU designs imagined by the company. For this role, we are seeking an engineer experienced in production management and team management.
Responsibilities
Organize, plan and oversee the day-to-day operations
Ensure that the requests of users are documented and complete Elaborate the planning of operations with the team and in compliance with users' constraints Contribute to the tasks of warm-up/cool down cycle and cabling modification Be responsible for the review of the work done Establish with the team standard operating procedures Lead improvement actions (A3…) Manage the stock and loop back with suppliers and purchasing team
Coordinate the team planning with company iteration cycles, ensuring coordination with other teams in the company
Cryostats and racks responsibility: Ensure that the tools and instruments under the team's responsibility are maintained up and running (following preventive maintenance plan and managing corrective/troubleshooting when necessary), to maximize the "up-time". Align with other team leaders on good practices and standard definition for architectures and HW implementation.
Systems fabrication & integration Oversee the in-house fabrication, assembly and integration of the platform's hardware systems, from components to fully operational setups. This includes:
Assembly of the cryostats
Build of the chandelier (cold cabling assembly / wiring tree inside the cryostat): mounting of the plates, thermalization, and cold RF/DC wiring
Assembly and wiring of the instrumentation and control racks
Interconnection between the cryostat, the chandelier and the racks (RF/coax, DC, control and monitoring lines)
Provide help and support to the design teams in the validation of the new systems (participation in test campaigns, execution of V&V procedures, feedback on manufacturability and operability)
Ensure that fabrication follows the standard procedures, quality checks and traceability, and feed back improvements to the design teams
Check final acceptance of new systems: Before entering into production, HPO team will proceed to an acceptance phase, ensuring that tools are qualified, documentation ready, and the team trained to operate them.
Budget responsibility: prepare and oversee budget for HPO team
Team Leadership & Supervision: Manage and inspire a team of engineers and technicians, fostering a collaborative environment. Supervise and motivate the team members. Define the profiles needed when necessary and drive with HR the hiring process. Provide mentorship and guidance, promoting professional growth and skill development within the team.
Continuous Improvement: Drive ongoing improvements in the team (both at a technical and organizational level).
Documentation & Reporting: Ensure standard operation procedures exist, and system configurations are thoroughly documented.
Requirements Educational Background: A Master degree in Electrical Engineering, Physics, or Production management
Experience
Proven experience (5+ years) in a production environment or a "critical infrastructure" environment.
Strong experience in management of a team.
Technical Skills
Knowledge of cryogenics is a plus
Knowledge of RF instrumentation is a plus
Leadership & Collaboration
A communicative and team‑oriented approach
Strong organizational skills, with planning ability (to coordinate tool usage and team schedule efficiently)
Ability to implement processes and actions to optimize and accelerate work tasks
Pragmatism, and ability to manage in real-time/operational context
English and French communication skills, both written and verbal
Ability to collaborate effectively with multidisciplinary teams
Commitment to quality
Service oriented approach
Attention to detail and ability to maintain thorough documentation of procedures, tests.
Nice to have
Desirable Skills & Experience (Optional But Not Required) Experience in quantum technologies.
