Job summary

Alice & Bob is building the first universal, fault-tolerant quantum computer and operates across two Île-de-France sites (Aubervilliers and Paris 15th). This hands-on, on-site role leads a team of engineers and technicians, ensuring uptime of cryostats, RF instrumentation, and assembly of new systems.

You will participate in validation campaigns, sign off on new hardware, and drive continuous improvement while collaborating with design teams.

Qualifications

• Master degree in Electrical Engineering, Physics, or Production management — or equivalent experience.
• 7+ years hands-on experience with RF/microwave measurement chains, cryogenic systems, test benches, or comparable critical experimental infrastructure.
• Real, practical command of RF instrumentation and signal chains (VNA or spectrum analyzer measurement, cabling integrity, troubleshooting).
• Experience leading a technical team, or clear readiness to step into your first team lead role.
• Strong planning instincts under real-world constraints (tool availability, maintenance windows, competing requests).
• Professional English; enough French to work day-to-day on-site, with French classes covered by the company if you want to build on it.

Responsibilities

• Keep the platform running
• Own the health and uptime of cryostats, wiring and instrumentation: preventive maintenance, corrective action, first-level troubleshooting
• Run routine V&V on RF and DC instrumentation, characterize the signal path, and catch drift before it becomes a problem
• Align with other team leads on RF and hardware architecture standards
• Plan and schedule the team's work against user requests and company iteration cycles
• Jump in yourself on cooldown/warm-up cycles and cabling changes when the team needs the extra pair of hands
• Build and maintain SOPs, manage stock, and keep supplier loops running (RF components, cryogenic consumables)
• Build and integrate new systems
• Oversee in-house assembly, from cryostat builds to cabling, racks, and full system integration
• Support the design teams through validation (test campaigns, V&V) and sign off on new systems before they enter production
• Lead and grow the team
• Manage and develop a team of engineers and technicians: 1:1s, mentoring, hiring
• Own the team's budget and drive continuous improvement
