Cryogenic & RF Platform Operations Manager H/F

Cryogenic & RF Platform Operations Manager H/F at Alice & Bob, Aubervilliers. A mid-level full time position in the Quantum Platform Operations team, listed under hardware engineering.

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

About the role

Nothing gets measured until a qubit is cooled to 10 millikelvin, wired, and instrumented — and you'll be the person who makes sure that chain never breaks. Between the chip and the measurement sits a full microwave chain: cold RF and DC wiring down the cryostat, attenuation and thermalization at every stage, then instrumentation and control racks at room temperature. That platform — our dilution cryostats and their measurement chains — is one of the company's most critical assets, and the Cryogenic & RF Platform Operations team owns it.

You'll lead that team: 7 engineers and technicians who run cooldown and warm-up cycles, modify cold and room-temperature RF and DC cabling on request, keep cryostats and instrumentation racks available and qualified, build new systems in-house, and act as the single entry point for our QPU design and characterization teams. Your mission is simple to state and hard to deliver: keep the platform available and reliable, because every hour it's down is an hour we're not measuring qubits.

Working conditions

The platform spans two sites in Île-de-France, Aubervilliers and Paris 15th, with regular travel between them (roughly 80% Aubervilliers, 20% Paris 15th). This is a hands-on, on-site role.

Recruitment process

• Screening Call with Alexandra Talent Acquisition Specialist (30 min)
• Hiring Manager Interview with Antoine, your future manager (45 min)
• Technical case study on site (60 min) — prepared and presented on the day, nothing to do beforehand
• Leadership and Fit Interview (60 min)

Requirements

• A 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 — in industry, in a large research facility, or on a pilot line
• Real, practical command of RF instrumentation and signal chains (VNA or spectrum analyzer measurement, cabling integrity, troubleshooting) — the kind of experience where you've personally built, wired, debugged or commissioned a system
• 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), and the pragmatism to make good calls with incomplete information
• 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
• Experience with dilution refrigerators or sub-kelvin cryogenics
• Microwave measurement at low temperature, or exposure to quantum technologies
• Lean or operational excellence practice
