Senior Superconducting Qubit Design
il y a 4 jours
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
As a Senior Superconducting Qubit Design Engineer, you will be part of the development of our new, cutting-edge microwave architecture embedding the superconducting resonators, and specifically designed to preserve and control their quantum states.
Your mission will be to develop, simulate and troubleshoot microwave circuits and their controls. You will work hand in hand with the experimental physicists building the quantum processor and develop state-of-the-art hardware to control and design an ever more complex system.
ResponsibilitiesSimulate on-chip circuits and package designs numerically to validate performance.Predict interface losses with high accuracy to inform material selection and design adjustments.Forecast inter-resonator couplings precisely using advanced modelling techniques.Design, develop, and troubleshoot room-temperature hardware, including filters and PCBs.Create the architecture and design for upcoming multi-qubit circuits to optimise connectivity and scalability.Requirements5+ years of relevant experienceAn MSc or PhD degree in electrical/microwave engineering or related subjects Solid experience with EDA software Ansys HFSS or similarDemonstrated proficiency in Python programming Strong knowledge in transmission line theory and wave propagation Knowledge of passive and active RF/MW components Experience in cryogenics and/or quantum mechanicsProfessional-level English proficiency, both written and spoken.BenefitsOur success is your success : own it with our BSPCE planDirect IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.Flexible remote policy, up to 40 % a monthA Parental Plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old childrenSubsidized membership with Urban Sports ClubMental health support with 25-day vacation policy (as per French law) + RTTHalf of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle usersCompetitive health coverage, with Helium/AxaMeal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchenFrench language courses covered by the company for those interestedRecruitment ProcessScreening Call with Grace, Talent Acquisition Specialist (30 min)Hiring Manager Interview with Felix (45 min)Technical Interview/Presentation with the team (60 min)Leadership/Fit Interview (45 min)Reference CheckResearch 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.
