Offer Description

Your responsibilities

Are you ready to revolutionize the calibration workflows within CMS and drive forward the future of particle physics research? We're seeking a dynamic individual to join our team as a High-Level Trigger Calibration Specialist. In this role, you'll conduct comprehensive analyses, collaborate on prototype design and testing, and integrate production-grade systems to enhance calibration efficiency and optimize online reconstruction. If you're passionate about pushing the boundaries of scientific discovery, we invite you to embark on this thrilling journey with us.

This position is in the context of the NextGen Triggers (NGT) project. The NGT project is a 5-year collaboration between the LHC experiments and the CERN Research and Computing Sector to push forward the use and impact of innovative Artificial Intelligence technologies and high-performance heterogeneous computing architectures for the LHC experiments' trigger selection, data processing, and theoretical interpretation, and foster the development of the required technical competencies. The innovation generated while working towards the needs of the High-Luminosity (HL)-LHC phases will provide critical insights to develop future detectors, data flows and theoretical tools.

Responsibilities: 

• Conduct a comprehensive analysis of the current calibration workflows within CMS, collaborating with existing team members to gather information about existing calibration procedures.
• Identify areas for improvement in the calibration process and assess the impact of non-optimal calibrations on the physics performance of the online reconstruction by analysing data to quantify calibration inaccuracies.
• Participate in the design and testing of a prototype system aimed at enhancing calibration efficiency, programming algorithms and analysing data to assess the effectiveness of the prototype in improving calibration accuracy and efficiency.
• Integrate and test the production-grade calibration system within the CMS online infrastructure, working closely with system administrators and software engineers to ensure seamless integration.
• Conduct thorough testing of the prototype in a realistic environment, simulating various scenarios to assess performance and reliability, and produce detailed reports evaluating the impact of improved online calibrations on the physics performance of the High-Level Trigger.

The successful candidate will be expected to work well within a team, including colleagues at CERN and collaborating institutes. There will also be opportunities to present their work at conferences/workshops at CERN and outside.
