Job Description

CERN, the European Organization for Nuclear Research, is seeking a highly skilled and motivated individual to join our team as an Applied Physicist on Event Reconstruction. This is a unique opportunity to contribute to the development of cutting-edge software for high-energy physics experiments.

Key Responsibilities
  • Design and develop innovative approaches to achieve nearly two orders of magnitude acceleration in the overall reconstruction time for the CMS high-level trigger processing step.
  • Collaborate closely with the Next Generation Trigger (NGT) initiative to leverage their progress and ensure consistent and reliable contributions to developing the CMS NGT high-level trigger project.
  • Develop and oversee a comprehensive validation suite to evaluate the physics and computational prowess of the reconstruction algorithms run during high-level trigger processing.
  • Integrate cutting-edge algorithms into the existing CMS High-level trigger reconstruction software.
  • Assist team members in adopting novel reconstruction algorithms and their products into their specific HLT paths.
  • Supervise doctoral students and fellows to ensure a well-rounded and impactful contribution to the broader research objectives.
Qualifications
  • PhD or equivalent relevant experience in Physics or Computer Science or a related field.
  • Experience in event reconstruction and software development for the High-Level Trigger at a high-energy physics experiment.
  • Experience in C++ programming, including the latest C++ standards (C++17 or later).
  • Knowledge of modern software development tools, including containerised environments, debugging tools, profiling tools, source code management (git), merge requests, CI/CD, issue tracking, and documentation.
Technical Competencies
  • Development of application software: advanced knowledge and application of software development for High-Level Trigger (HLT) and event reconstruction at high-energy physics experiments.
  • Knowledge of programming techniques and languages: strong proficiency in C++ with practical application of the latest standards (C++17 and later) and object-oriented programming principles.
  • Simulation, design and development of trigger, data acquisition chains: expertise in designing and implementing HLT menus and trigger paths for optimised real-time performance.
  • Knowledge and application of software life-cycle tools and procedures: proficient use of containerised environments, debugging, profiling, source code management (Git), CI/CD pipelines, and issue-tracking tools.
Behavioural Competencies
  • Solving problems: addressing complex problems by breaking them down into manageable components.
  • Achieving results: delivering high-quality work on time and fulfilling expectations.
  • Learning and sharing knowledge: keeping up-to-date with developments in own field of expertise and readily absorbing new information.
  • Working in teams: working well in groups and readily fitting into a team.
  • Demonstrating flexibility: demonstrating openness to new ideas and situations.
Language Skills

Spoken and written English: ability to understand and speak the language in professional contexts.
