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.
Responsabilities
-
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)
- 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
- Manage and develop a team of engineers and technicians: 1:1s, mentoring, hiring
- Own the team's budget and drive continuous improvement
Run day-to-day operations
Build and integrate new systems
Lead and grow the team
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
