Nanofabrication back end technician F/H

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. Compared to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously.

We are a diverse team of 180+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault‑tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us and help shape the future of quantum computing.

About the Role

As a nanofabrication backend technician , you will play a key role in bringing the QPU designs imagined by the company into reality. Your technical expertise and meticulous attention to detail will directly contribute to our technical excellence and speed of execution, shaping the future of quantum computing.

The Team Is In Charge Of
