Job DescriptionAs part of the software team of the group, you will work on the upgrade of the Beam Interlock System (BIS) and Safe Machine Parameters system (SMP), which are key protection systems for the safe and reliable operation of the whole accelerator chain.Both systems are undergoing a major overhaul, starting from their components and extending to software elements: data acquisition, control, supervision and monitoring. While each have their own purposes, use-cases and domain specificities, the two systems share the same technical stack: low level C++ real-time controls application, Java data transformation layer, Python and Angular GUIs, and integrations within the wider CERN accelerator controls.Key aspects of the job include extending the reference model of the SMP system, implementing the real-time controls application integrating with the SMP and BIS hardware elements, as well as the upper software layers (Java, Python, Angular), and facilitating their integration with other software systems and the accelerator controls environment.Your responsibilities:
  • Contribute to the development, testing, and maintenance of software components for the BIS and SMP systems (real-time control, data processing, and user interfaces).
  • Support the collection of requirements and feedback from users and hardware experts; assist in maintaining and extending the SMP reference model.
