At 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. Find out more on http://home.cern.
Introduction
Are you an expert in software engineering or applied physics with expertise in online reconstruction and high-level trigger (HLT) development? Do you have a strong passion for developing performant software for event reconstruction in high-energy physics experiments? Then apply for this unique challenge as the next step in your career. CERN, take part!
You will join the Next Generation Trigger (NGT) initiative at CERN. As part of our commitment to pushing the boundaries of scientific exploration, we are embarking on the Real-time Reconstruction Revolution (R³ - Rcube) project. This initiative aims to rethink the traditional CMS Phase-2 High-Level Trigger (HLT) reconstruction system by leveraging heterogeneous computing resources, adopting contemporary development methodologies and integrating modern AI-driven techniques.
Functions
You will take on key responsibilities in the Real-time Reconstruction Revolution (R³ - Rcube) project. You will dive into the formidable challenges of achieving nearly two orders of magnitude acceleration in the overall reconstruction time, including particle flow, jets/MET, muon, taus, and E/Gamma for the CMS high-level trigger processing step. Your activities will include:
Conduct a critical assessment of the current high-level trigger reconstruction performance, and design and develop innovative approaches that push the boundaries of existing methodologies. Implement advanced algorithms, incorporating GPU acceleration, heterogeneous architectures, and AI technologies to enhance event reconstruction at the HLT.
Collaborate closely with NGT Task leaders to leverage their progress, align their efforts with your requirements, and ensure consistent and reliable contributions to developing the CMS NGT high-level trigger project.
Develop and oversee a comprehensive validation suite and evaluating the physics and computational prowess of the reconstruction algorithms run during high-level trigger processing.
Collaborate closely with the team, you will integrate these cutting-edge algorithms into the existing CMS High-level trigger reconstruction software.
Assist various team members in adopting the novel reconstruction algorithms developed and their products into their specific HLT paths.
In this dynamic role, you will not only tackle the present challenges but also provide crucial technical guidance and mentorship to propel the project toward creating the CMS HLT community of tomorrow, a necessity in anticipation of the HL-LHC era.
Additionally, you will supervise doctoral students and fellows ensuring a well-rounded and impactful contribution to the broader research objectives.
