High-Level Trigger Calibration Scientist (EP-CMS-TDQ-2026-150-GRAP)

A monthly net stipend of either 6372 or 7004 Swiss Francs per month depending on your degree.

Your responsibilities

• Work with the CMS Detector Performance Groups (DPGs) and Physics Object Groups (POGs) to develop new and improve calibration algorithms.
• Maintain the successful NGT Demonstrator System, developed during LHC Run 3, ensuring it remains operational and capable of running in replay mode against archived data throughout Long Shutdown 3.
• Building on the NGT Demonstrator System experience, contribute to the design of a realistic, production-grade NGT Data Acquisition and Calibration System implementing the Optimal Calibrations required for CMS's High-Level Trigger during the HL-LHC era.
• Integrate and test the production-grade system within the CMS online infrastructure, working closely with system administrators and software engineers to ensure seamless compatibility.
• Conduct thorough testing of the NGT system in a realistic environment, simulating various LHC and CMS operational scenarios to assess performance and reliability.
• Produce detailed reports evaluating the impact of improved online calibrations on the physics performance of the High-Level Trigger.
• This role includes team supervision responsibilities.
