Safety and Controls Engineer for the CMS Experiment

Join the CERN team working on the Compact Muon Solenoid (CMS) experiment to design, develop, test, procure, implement, operate and commission highly reliable PLC-based SCADA systems for detector control and environmental safety. The role supports next-generation upgrades such as the High Granularity Calorimeter (HGCAL) and Tracker detectors, ensuring safe and stable operation in extreme conditions.

Responsibilities

• Coordinate a team of experts from the HGCAL CMS detector system to ensure coherence and synergy with the rest of CMS throughout procurement, construction, commissioning, and operational phases of the SEP/DCS.
• Finalise the development, procurement and implementation of necessary hardware for the HGCAL SEP, including PLCs, environmental sensors, and intermediate hardware at all levels on the CMS site.
• Develop the DCS software tree for control and monitoring of all HGCAL hardware to enable rapid identification of issues by non-experts and semi-experts.
• 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.
• Develop and test the action matrices for the HGCAL SEP at all levels to ensure safe and efficient operation.
• Ensure proper documentation of the SEP and DCS is updated and stored to integrate the HGCAL DCS and SEP into the central CMS system.

Requirements

• Master's degree or equivalent relevant experience in the field of Electrical Engineering or a related field.
• A strong track record in the design, implementation, testing, operation, and maintenance of large PLC-based SCADA systems, including the development of feedback loops and interlock mechanisms.
• Proven ability to program PLCs and develop/maintain software to interface to PLCs and monitor/archive sensor-based data and execute actions according to the data, such as alarming and interlocking.
• Skills in evaluating environmental sensors (e.g. humidity, temperature, smoke) for long-term reliable performance in harsh environments.
• Experience evaluating such sensors in high magnetic and radiation fields will be an advantage.
• Proven experience with industrial control software (e.g. WinCC-OA) for the monitoring and control of large, complex systems.
• Basic knowledge of procurement of industrial and custom devices, including liaising with companies and following up on production.
• Proven ability to work successfully within multinational and multicultural teams of scientists and engineers would be an advantage.
• A valid driving licence.
• Willingness to work during nights, Sundays and official holidays, when required by the needs of the Organization.
• Ability to work in Radiation Areas and perform interventions in underground installations.
