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 We're looking for a Quantum Compilation Scientist to join our growing compilation team. You'll design and optimize the software toolchain that translates quantum programs into physical gate operations on our processors. This is a cross-disciplinary role spanning quantum physics and computer science. Your first major focus: integrating our latest architectural advances into the resource estimator, so our systems scale efficiently without sacrificing performance.
