Quantum Scientist

Quantum Scientist - Device Theory (Firmware) Join to apply for the Quantum Scientist - Device Theory (Firmware) role at Alice & Bob. Alice & Bob is developing the first universal, fault‑tolerant quantum computer to solve the world’s hardest problems. Our quantum computer is based on a new kind of superconducting qubit – the Schrödinger cat qubit – which offers autonomous error correction. We are competing with tech giants such as Google and IBM, and we have secured €100 million in funding (2025) to evolve our technology. With a team of 100+ talented physicists, PhD students, engineers and business professionals, we aim to reshape the future of quantum computing. About the Role The Performance Optimisation team uses advanced ML and optimisation tools to improve the performance of Alice & Bob’s quantum processors. As a Quantum Scientist – Device Theory, you will refine theoretical models of our cat qubits, develop efficient numerical methods to study their dynamics, and integrate these models into the firmware platform that operates our processors. You will collaborate with physicists, engineers, and ML researchers to solve practical challenges in quantum computing. Responsibilities Develop theoretical models of Alice & Bob's dissipative cat qubits implemented with superconducting circuits. Create efficient numerical methods to study the dynamics of our systems. Collaborate with quantum experimentalists, machine‑learning researchers, and engineers to analyse and understand experimental data. Contribute to the development of machine‑learning methods to optimise device performance. Requirements PhD in quantum physics, focused on the theory of superconducting devices. Lead‑author publications on device theory in top‑tier physics journals. Expertise in modern numerical and analytical tools for modelling superconducting circuits. Proficiency in Python programming. Excellent communication and collaboration skills for cross‑functional teamwork. Professional‑level English proficiency, written and spoken. Nice to Have Curiosity about machine‑learning. Strong sense of ownership and attention to detail, ensuring quality and completeness of projects. Benefits Success‑share: own it with our BSPCE plan. Direct IP compensation: earn substantial bonuses for core patents. Flexible remote policy, up to 40 % of the month. Parental plan including crèche support or additional days‑off for children under 12. Subsidised membership with Urban Sports Club. Mental health support via moka.care. 25‑day vacation (French law) + RTT. Half of transportation cost coverage (French law) or yearly allowance for bicycle users. Competitive health coverage with Helium/Axa. Meal vouchers with Swile and access to a fully stocked kitchen. Company‑covered French language courses for interested employees. Recruitment Process Screening call with Grace, Talent Acquisition Specialist (30–45 min). Hiring manager interview with Jérémie, VP Firmware (45 min). Technical interview/presentation with the team (60 min). Leadership/fit interview (45 min). Reference check. Research shows that women might feel hesitant to apply for this job if they don’t match 100 % of the requirements. This list is a guide, and we welcome applicants who are only a partial match. We are building teams that innovate, not just tick boxes. Join one of France’s most innovative early‑stage startups to build the first universal quantum computer. We celebrate learning, shared ideas, and personal growth.
