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're a diverse team of 250+ brilliant minds from over 35 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 let's shape the future of quantum computing together! About the role: As a Senior HPC Engineer, you will play a central role in scaling and optimizing the computational backbone of our chip simulation workflows. Collaborating closely with quantum theorists, experimentalists, and software engineers, you will design, optimize, and maintain high-performance scientific software and compute backends that support quantum chip design and calibration.
