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 are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.
Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future!
About the Role:
Alice & Bob is transitioning from a cutting-edge research lab to a product-focused quantum computing company. As part of this transformation, we’re creating Quantum HPC, a new team bridging technical expertise and customer engagement.
We’re looking for a Quantum Hardware & Physics Specialist to join this team. You will play a key role in technical conversations with HPC centers, our natural early adopters and help shape how our superconducting “cat qubits” are understood, integrated, and used.
Responsibilities:
- Lead technical meetings with HPC clients and partners
- Present our core technology: superconducting cat qubits, roadmap to FTQC, integration challenges
- Convey complex scientific ideas and the vision of Alice & Bob to technical and non-technical audience in a clear and accessible manner (in talks, hackathons, workshops, meetings…)
- Prepare high-quality technical content: briefs, diagrams, comparison tools, slides
- Contribute to internal work on machine development in accordance with your expertise: experiments, theory, specifications, cryogenics, RF, hardware/software stack…
- Interact with customers as a scientific expert
- Help align our internal tech development with real-world constraints and needs
Requirements:
- PhD or MSc in quantum physics, superconducting circuits, or similar field, with 3 years of experience
- Comfortable navigating between lab-level details and real-world applications
- Excellent communication skills with both technical and non-technical audiences. Experience with customer-facing role (US and Europe).
- (Bonus) Familiarity with HPC environments, cryogenics, or RF systems
- Curious, proactive, and eager to build something meaningful in the quantum space
- Fluent in professional English & French, both written and spoken.
Benefits:
- 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 benefits with Helium/AXA.
- Meal vouchers with Swile + access to a fully-equipped kitchen.
- Parental benefits with crèche support
- Flexible remote policy, up to 40 % a month.
- Mental health support with moka.care
- Subsidized membership with Urban Sports Club
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.
