Superconducting Qubit Design Engineer

Join to apply for the Superconducting Qubit Design Engineer (Microwave) role at Alice & Bob1 month ago Be among the first 25 applicantsJoin to apply for the Superconducting Qubit Design Engineer (Microwave) role at Alice & BobAlice & 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 futureAs a 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.ResponsibilitiesNumerical simulations for the on-chip circuits and its packagingAccurate prediction of interface lossesAccurate prediction of inter resonator couplingsDesign, development and troubleshoot of room temperature hardware (filters, PCBs, etc.)Design of the architecture of the upcoming multi-qubits circuitsRequirementsAn MSc or PhD degree in electrical/microwave engineering or related subject, with 6+ years of relevant experienceExperience with EDA software Ansys HFSS or similarExperience in Python programmingStrong knowledge in transmission line theory and wave propagationKnowledge on passive and active RF/MW componentsExperience in cryogenics and/or quantum mechanics25-day vacation policy (as per French law) + RTTHalf of transportation cost coverage (as per French law), or yearly allowance for bike enthusiastsCompetitive health benefits with Helium/AXAMeal vouchers with Swile, as well as access to a fully equipped kitchenParental benefits with crèche supportFlexible remote policy, up to 40 % a monthLanguage courses covered by the companyMental health support with moka.careSubsidized membership with Urban Sports ClubRecruitment processScreening Call with Sabrina, Talent Acquisition Manager (30 min)Hiring Manager Interview with Felix (45 min)Technical Interview/Presentation with Felix, Danielius, Emanuele, and Przemek (60 min)Fit Interview (30 min) with 2 team members from a different departmentFounders/Leadership Team Interview (30 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.
