The Role
The Senior Software Engineer will develop and maintain software solutions, mentor junior engineers, and enhance critical workflows for quantum computing.
Summary Generated by Built In
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!
The Framework team is a central resource, working across the organisation with researchers and technicians, and is fundamentally integrated into the workflows. As a Senior Software Engineer on this team you will play a key role in designing, developing, and maintaining high-quality software solutions.
