Role
Who you are
- Experienced: 3+ years of experience as a Software or Full Stack Engineer in a cloud environment
- Proficient in Python: Strong backend experience, with a good grasp of modern Python, FastAPI or similar frameworks, and asynchronous programming
- Frontend-Capable: Comfortable with React (or similar frameworks) and understand how to build and maintain SPAs
- DevOps-Minded: Experience working with containers (Docker/Podman), CI/CD workflows, and infrastructure tools like Ansible
- Infrastructure-Aware: Familiar with modern deployment environments, including Kubernetes (on-prem or in the cloud) and VM-based setups
- Collaborative Leader: Able to mentor others, lead by example, support a growing team, and help apply best practices
- Product-Focused: You understand user needs and care about delivering useful, maintainable, and well-documented software
- Experience working in high-performance computing, hardware control systems, or quantum/physics-driven and product-driven environments
- Contributions to open-source projects
- Familiarity with GitLab (projects, issues, CI/CD)
- Understanding of authentication and user access control (OAuth2, Keycloak, etc.)
What the job involves
- The Cloud team empowers quantum hardware with software, creating tools for users. We seek a Senior Software Engineer to architect, mentor, and lead product delivery

Our take
Creating top-tier quantum hardware, including qubits and control electronics, presents a significant hurdle for those pursuing high-power quantum computing. Various qubit technologies exist, each boasting unique advantages and drawbacks, with the most recent research in the sector involving the pursuit of a scalable, fault-tolerant qubit technology.
Joining this pursuit is Alice & Bob, a company specialising in "cat qubits". This technology, named for Schrodinger’s infamous cat, is able to reduce hardware requirements, promising fault-tolerant quantum computing at scale. With over 90 employees and pioneering experimental results, Alice & Bob has notable achievements, including the development of its 16-bit Helium 1 quantum processing unit.
Recognised for its ground-breaking work, Alice & Bob recently received a hefty innovation grant that will support its work moving forwards. Through projects like "Cat Factory," in collaboration with academic partners, the company aims to optimise quantum computation infrastructure, making it more cost-effective and market-ready and ultimately building "the first universal quantum computer”.
