Python Software Engineer

As a Python Software Engineer with a strong interest in both API development and desktop application engineering (with PyQt6), you will work on tools at the heart of CERN’s accelerator complex, used daily across operations, engineering, and physics.

This role spans the Python APIs that interface to the CERN control system, and the PyQt6-based desktop applications built on top of them.

On the API side, you will develop frameworks, libraries, and bindings integrating tightly with backend control system services, with a strong emphasis on developer experience, robustness, and long-term maintenance.

On the UI side, you will work on applications for operating, monitoring, and configuring accelerator systems, ensuring reliable, responsive, and effective user experiences.

You will collaborate with colleagues across the organisation, contributing to design reviews, documentation, training, and technical support, while staying abreast of relevant emerging technologies and playing an active part in shaping the future of CERN’s accelerator control system.
