Senior Scientific Software Engineer

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!

Responsibilities

• Architect, implement, and optimize high-performance scientific software components and simulation kernels, while establishing best practices for software quality, testing, and maintainability.
• Lead development and evolution of the simulation environment used to integrate, orchestrate, and execute quantum chip simulations.
• Drive the onboarding and promotion of simulation tools across the organization, demonstrating capabilities, gathering user feedback, and helping shape the tooling roadmap.
• Support simulation studies, including the execution of simulation pipelines.
• Partner effectively with quantum scientists, researchers, and cross-functional colleagues.

Requirements

• PhD or Master’s degree in Applied Mathematics, Scientific Computing, Quantum Physics, or related field.
• 5+ years of experience, including 2+ years in an industrial environment.
• Proficiency in Python and JAX, with strong software engineering skills, including version control (Git/GitLab), CI/CD pipelines, automated testing, code review, and software maintainability best practices.
• Experience with scientific computing ecosystems (e.g., NumPy, SciPy, JAX, PETSc, or equivalent), and familiarity with HPC environments (CPU/GPU).
• Hands-on experience running simulations or using scientific simulation software (e.g., Ansys, COMSOL, or similar).
• Professional-level English proficiency, both written and spoken.
