Full Job Description
At [CERN](http://home.cern), the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Introduction: 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. Functions: * Design and maintain Python bindings to the accelerator control system, using a range of technologies such as REST, gRPC, event-driven messaging (e.g. ZMQ), as well as bindings to existing C++ and Java libraries. * Build reusable components, widgets, and libraries supporting control application development at CERN. * Develop and maintain a number of PyQt-based control applications used in the CERN Control Centre. * Contribute t
