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 a Senior Software Engineer at Alice & Bob, you will play a key role in designing, developing, and maintaining high-quality software solutions. You will also contribute to our core products and drive innovation while building our in-house software which controls the hardware equipment and the experiments that we perform. Working as a technical leader, you will mentor junior engineers and contribute to architectural decisions.
Responsibilities:
- Hands on development, maintenance and testing of the software code.
