Software Engineer

About this role

Responsibilities

• As a Software Engineer, you will develop Python applications that support the simulation, automation and operation of radiofrequency systems across CERN's accelerators.
• You will contribute to the full software lifecycle, from understanding user needs and designing solutions to testing, deployment and operational support.
• You will also collaborate with developers working on C++ real-time control software and contribute to tools and interfaces that connect high-level applications with low-level hardware systems.
• Your responsibilities:
• Design, develop, and maintain Python-based software applications and tools for the configuration, monitoring, automation, commissioning, and analysis of RF systems across CERN's accelerator complex.
• Collaborate with engineers and physicists to understand operational requirements and deliver reliable, user-focused software solutions integrated with real-time control systems and C++ middleware components.
• Develop automation, testing, and deployment workflows using modern software engineering practices, including CI/CD, containerised environments, and maintainable software architectures.
• Participate in the deployment, commissioning, operational support, and continuous improvement of software systems used during accelerator operation, including on-call support activities.
• Contribute to technical documentation, knowledge sharing, and software quality practices within the team and the wider controls software community.
• Still here?
• Let's make a quick check about:
• Your profile:
• Solid Python development skills, ideally including scientific libraries (NumPy, SciPy, Matplotlib) and GUI frameworks (PyQt).
• Understanding of C++ sufficient to read and interface with existing control-system code.
• Knowledge of software engineering processes: version control (Git), testing, CI/CD and containerisation.
• Experience delivering production-quality software in scientific or engineering environments.
• Exposure to radiofrequ
