Safety and Controls Engineer for the CMS Experiment
About this role
What you'll do
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

- Your responsibilities
- 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).
- Develop the DCS software tree for control and monitoring of all HGCAL hardware, such that rapid identification of issues by non-experts (e.g. by the CMS Technical Shifter) and semi experts (HGCAL on-call personnel) is fast and efficient.
- Finalize the SEP and DCS for commissioning and operation of the full HGCAL underground, installed in CMS.
- Help ensure the HGCAL feedback control and monitoring for the thermal screen and cooling are fully developed, tested, and debugged
