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

Job description

About the role

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'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!

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

Requirements

Educational Background

• A Master degree in Electrical Engineering, Physics, or Production management — or equivalent experience.

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
• Nice to have
• Experience with dilution refrigerators or sub-kelvin cryogenics
• Microwave measurement at low temperature, or exposure to quantum technologies
• Lean or operational excellence practice

Working conditions

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)

• Our success is your success: own it with our BSPCE plan
• Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
• A Parental plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
• Subsidized membership with Urban Sports Club
• Mental health support with moka.care
• 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 coverage, with Alan.
• Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
• French language courses covered by the company for those interested

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.
