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. We are growing fast, securing 30 million USD of funding in 2022 to develop our unique technology.

We are 80 and counting, between physicists, PhDs, engineers and experienced business professionals, all united in reaching our ambitious goal. If you are an explorer, craving to challenge yourself and make quantum computing come true, come and join us!

As a Quantum Microwave Engineer, you will develop and innovate in the realm of microwave architecture for superconducting resonators. Engage in hands-on development, simulation, and troubleshooting of microwave circuits and controls. Collaborate closely with experimental physicists to create the quantum processor, developing sophisticated hardware for enhanced system control and design.

Responsibilities

    • Conduct numerical simulations for on-chip circuits and their packaging.
    • Predict interface losses and inter-resonator couplings with precision.
    • Design and troubleshoot room temperature hardware including filters and PCBs.
    • Architect multi-qubit circuit systems for future quantum computing advancements.

Requirements

    • MSc or PhD in Electrical/Microwave Engineering or a related field.
    • Minimum 5 years of relevant experience.
    • Proficiency in Ansys HFSS, Python programming, and PCB layout software.
    • Deep understanding of transmission line theory, wave propagation, and RF/MW components.
    • Experience in cryogenics and/or quantum mechanics is highly desirable.

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 Alan
    • Meal vouchers with Swile, as well as access to a fully equipped kitchen
    • Parental benefits with crèche support
    • Flexible remote policy, up to 25 % a month.
