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!
As Instrumentation engineer and part of the Hardware Platform Operation Team, you will be in charge of operating, maintaining and implementing in mechanical racks cutting-edge instrumentation systems, that are central to our quantum processors. Instruments include RF and DC sources, as well as Vector Network Analyzer, Oscilloscopes and spectrum analyzers. You will also support the users in their daily experiments and characterization, the goal of the team being to focus 100% on operational excellence and quality, to ensure the highest availability rate.
