Software Engineer – Python for RF Systems

About the role

As a Software Engineer at CERN you will develop Python applications that support the simulation, automation and operation of radio‑frequency (RF) systems across the accelerator complex. You will work across the full software lifecycle, from gathering user requirements to design, testing, deployment and operational support. Collaboration with C++ real‑time control developers and accelerator physicists is a core part of the role.

Key responsibilities

• Design, develop and maintain Python‑based tools for configuration, monitoring, automation, commissioning and analysis of RF systems.
• Integrate software solutions with real‑time C++ control middleware and accelerator hardware.
• Create and maintain CI/CD pipelines, containerised environments and automated testing workflows.
• Provide on‑call operational support during accelerator runs, including deployment and troubleshooting.
• Produce technical documentation and share knowledge within the controls software community.

Required profile

• Master’s degree or equivalent experience in Computer Science, Software Engineering, Applied Physics, Electronics Engineering or related field.
• Proven experience delivering production‑quality software in scientific or engineering environments.
• Ability to understand and interface with C++ control‑system code.
• Familiarity with radio‑frequency or accelerator systems is a plus.

Required skills

• Python programming, including NumPy, SciPy, Matplotlib.
• GUI development with PyQt.
• C++ (reading and interfacing).
• Version control with Git.
• CI/CD concepts and tools.
• Containerisation (e.g., Docker).
• Software testing and debugging.
