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 At Alice & Bob, Marketing translates frontier quantum research into powerful, accessible narratives. We work directly with our physicists and engineers to build deep credibility with technical audiences. We are a lean, hands-on team where everyone ships high-impact work to build the most respected and beloved brand in quantum. About the Mission Your mission is to own and scale our social media and email channels end-to-end—driving everything from growth strategy to content and community. While you'll collaborate with R&D, Marketing leadership, and creative partners for heavy production, the creative spark, vision, and execution strategy must come from you. About You Are you a hands-on builder who lives at the intersection of science and storytelling? We need an exceptional communicator to design and lead our new marketing function. This isn’t about basic marketing; it’s about managing complex stakeholder landscapes, fueling community growth, and intuitively knowing the difference between good and legendary content.
