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: You will work at the forefront of applying artificial intelligence to accelerator control systems and operational workflows at CERN. Working collaboratively across the BE-CSS group and the broader Accelerator and Technology Sector (ATS), you will design, develop, and deploy practical AI solutions — from LLM-based knowledge assistants to agentic AI workflows. A defining aspect of your role will be contributing to the newly established ATS AI Core Team, where you will provide expertise in LLM and agentic AI systems, secure knowledge connectors, and safe agent deployment patterns. Your work will span hands-on software development, cross-group collaboration, and technical leadership — an excellent opportunity to work alongside engineers and scientists from across CERN and to shape the organisation’s AI capabilities in a meaningful and lasting way. Functions: * Contribute to the AI-driven evolution of the BE-CSS group’s software product portfolio, identifying and implementing opportunities to embed AI capabilities across group applications. * Design and develop LLM-based solutions, including a first-line support chatbot backed by retrieval-augmented generation (RAG) pipelines, vector databases, and secure knowledge connectors, in close collaboration with the CERN IT department providing the underlying MLOPs substrate. * Join the ATS AI Core Team and take a major role in the rollout of LLM/agentic AI and knowledge systems, contributing to reusable patterns, evaluation frameworks, and s
