Software Engineer (SY-RF-CS-2026-117-LD)

Introduction:

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.

Functions:

• 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.
