Senior Electronics and System Integration Engineer H/F

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 \uD83D\uDC08‍ . 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!

About the Role

Every quantum computer we build depends on getting the physical foundations right — and that's where you come in.

In a context of rapid scale-up of Alice & Bob's quantum computing hardware, you'll be the key link that brings together the many sub-components, instruments, cabling, racks, and custom electronics into reliable, production-ready systems. Reporting to the HERMES Team Lead, our electronics and systems integration team, you'll work closely with physicists, RF engineers, and mechanical engineers to design scalable rack and wiring architectures, reduce system footprint through custom PCB design, and bring innovative integration solutions that keep pace with the team's growing installation needs.

Responsabilities

• Design and integrate electronics systems for our quantum computing set-ups, including custom PCBs, robust rack and cryostat assemblies, and the tooling needed to support implementation
• Integrate equipment into racks and cryostats, manage wiring across instruments, and drive the scale-up of installations across the team's scope
• Design and run validation tests, analyze results, and troubleshoot issues across mechanical, electronic, and control-electronics systems
• Source, evaluate, and negotiate with equipment and component suppliers, keeping an eye on state-of-the-art instrumentation
• Work closely with physicists, RF and mechanical engineers to define hardware architectures, and document your work along the way

Requirements

• Engineering degree (or equivalent) in Electronics, Electrical Engineering, or a related field
• 5+ years in electronics design and system integration, ideally including PCB design and lab/instrumentation environments
• Strong hands-on skills across electronics design (analog/RF/DC), PCB design tools (KiCad/Altium), cabling and rack integration, and lab instrumentation (VNAs, spectrum analyzers, oscilloscopes)
• Comfortable with Python scripting for tooling, testing, or automation
• A pragmatic troubleshooting mindset and a knack for inventing simpler, more scalable integration solutions
• Sourcing and supplier management skills, and strong documentation and cross-team communication
• Proficient in English, French is a big plus

Nice to have

• Knowledge of digital electronics or GPU integration

Benefits:

• 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 withUrban 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.
