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 are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology. Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future! About the role The EDA Research team is developing the tools that predict the performance of our superconducting QPU designs. These tools are essential in the chip design process at Alice & Bob. Our predictions are currently computed using a pipeline of simulation tools, including FEM software for electromagnetic problems, frameworks for approximations of quantum problems, and efficient numerical solvers. As an Expert Optimization Engineer, you will be responsible for developing and applying mathematical optimization tools to fine-tune chip design parameters. This work involves integrating closely with the existing simulation framework to maximize QPU performance metrics. Responsibilities

Lead research and development of optimization tools for numerical and scientific software for chip design simulation

Communicate with users and collect feedback to align the vision for the optimization workflows

Identify limitations in current simulation pipeline and help build improvements needed to meet optimization targets

Assess overall numerical performance of simulation pipeline and work with other simulation engineers to implement necessary improvements

Write specifications for software engineers and collaborate to industrialize and deploy processes

Requirements

3+ years of academic or industrial experience in optimization and large-scale numerical applications

MSc or PhD in mathematics, engineering, physics or related field

Solid experience with efficient numerical solvers
