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!

As part of a fast-moving quantum computing start-up, the Building & Facilities Maintenance Technician will ensure the smooth operation, safety, and compliance of all building systems and site infrastructure. This includes maintaining critical laboratory environments, clean rooms, cryogenic facilities, and core building services across multiple development sites. The role demands adaptability, a proactive approach, and the ability to work in an environment where R&D priorities can shift rapidly.


Responsabilities
  • Facilities & Infrastructure Maintenance
  • Carry out preventive and corrective maintenance on:
  • HVAC systems for clean rooms and laboratories (temperature, humidity, and particle control)
  • Cryostat-supporting infrastructure (cooling water, compressors)
  • Electrical distribution and backup systems (including UPS and generator checks)
  • Plumbing, purified water systems, and compressed gas lines
  • Building structure, security systems, and controlled-access installations
  • React quickly to unplanned breakdowns to minimize R&D disruption.
  • Laboratory & Quantum Facility Support
  • Maintain clean room integrity by monitoring pressure differentials, filtration, and gowning protocols.
  • Assist in the safe operation and support of cryogenic systems, following specialist engineers’ guidance.
  • Monitor and support environmental conditions vital for quantum hardware stability (e.g., temperature stability, vibration control).
  • Safety, Compliance & Standards
  • Work in accordance with ISO 45001 occupational health & safety, ISO 14001 environmental management, and ISO 50001 energy efficiency principles.
  • Support risk assessments, incident reporting, and the control of hazards specific to high-tech laboratories (e.g., cryogens, high voltage, laser safety).
  • Maintain safe work practices in line with NEBOSH and company safety training.
  • Monitoring, Reporting & Documentation
  • Use the CMMS (computerized maintenance management system) to log all work orders, inspections, and repairs.
  • Maintain accurate service histories for facility and lab support equipment.
  • Provide daily/weekly reports to the Maintenance Planner on system performance and urgent issues.
  • Emergency Preparedness & Rapid Response
  • Respond immediately to alarms or urgent issues (HVAC failure, power loss, water leaks, cryostat cooling interruption).
  • Participate in crisis simulations and support emergency interventions following the company’s crisis management plan.
  • Continuous Improvement & Start-up Agility
  • Identify and propose cost-effective improvements to facility reliability, safety, and energy use.
  • Support rapid prototyping or ad-hoc facility modifications needed for evolving R&D projects.
  • Embrace multi-skilled work to adapt to the varied demands of a growing start-up.


    • Profile
  • Education: Technical diploma or vocational certificate in mechanical, electrical, building services, or HVAC engineering**.**
  • Experience: 3+ years in building/facility maintenance in a high-tech, semiconductor, research, or clean room environment; start-up experience is a plus.
  • Knowledge:
  • Clean room systems & contamination control
  • Cryogenic safety principles -> optional
  • Building automation systems (BMS)
  • Energy efficiency measures
  • ISO management systems awareness
  • Skills:
  • Strong troubleshooting and quick decision-making under pressure
  • Ability to work independently and in cross-functional teams
  • Competence in reading technical diagrams and SOPs
  • Certifications (desired):
  • HVAC/EPA refrigerant handling certification
  • Cleanroom operations training
  • Basic cryogenic safety training


    • Benefits
  • 25-day vacation policy (as per French law) + RTT
  • Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
  • Competitive health benefits with Helium/Axa
  • Meal vouchers with Swile, as well as access to a fully equipped kitchen
  • Parental benefits with crèche support
  • Flexible remote policy, up to 40 % a month
  • Language courses covered by the company
  • Mental health support with moka.care
  • Subsidized membership with Urban Sports Club


    • Recruitment Process
  • Screening Call with Alex Talent Acquisition Specialist (30 min)
  • Hiring Manager Interview with one of the Experimentalist Team Leader (45 min)
  • Technical Interview/Presentation with the Team (60 min)
  • Leadership and Fit Interview (45 min)


    • Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.

    You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer!

    We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
