Quantum Hardware

Overview 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 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 Flexible remote policy, up to 40 % a month 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 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. #J-18808-Ljbffr
