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 Join the CERN team working on the Compact Muon Solenoid (CMS) experiment, one of the most advanced scientific instruments in operation. In this role, you will design, develop, test, procure, implement, operate and commission highly reliable PLC-based SCADA systems for detector control (DCS) and environmental safety and protection (SEP), supporting next-generation upgrades such as the High Granularity Calorimeter (HGCAL) and Tracker detectors. You will ensure safe and stable operation in extreme conditions by implementing monitoring and feedback systems that manage temperature, humidity, and cooling processes, contributing to the long-term performance of critical particle detection infrastructure. This position is to develop and commission the full DCS/SEP for the HGCAL. Functions * Coordinate a team of experts from the HGCAL CMS detector system to ensure coherence and synergy with the rest of CMS. Ensure this coherence continues throughout the procurement, construction, commissioning, and operational phases of the overall SEP/DCS. * Finalise the development, procurement and implementation of the necessary hardware for the HGCAL SEP, including PLCs, environmental sensors, and intermediate hardware (e.g. multiplexers for temperature sensors) at all levels on the surface at the CMS site: from single cassette tests (warm), multi-cassettes (up to 10 at a time, warm and cold), HGCAL sectors (up to 55 cassettes, warm and cold) and full endcaps (330 cassettes per endcap warm and cold). *
