CEA/IRFU recrute un ingénieur spécialisé en traitement de données et IA pour participer au développement d’un modèle fondation dédié à la physique des particules, destiné à répondre aux défis du HL-LHC et à traiter d’énormes volumes de données.
Vous intègrerez une équipe pluridisciplinaire et contribuerez au design, à l’entraînement et à l’évaluation de modèles IA, au développement de pipelines de données et à la publication des résultats scientifiques et techniques.
Irfu is recruiting an engineer specialized in data processing and artificial intelligence (AI) / deep learning as part of the development of a foundation model dedicated to particle physics to address the scientific and technological challenges of the High‑Luminosity Large Hadron Collider (HL‑LHC).
Scheduled to begin operation around 2029, the HL‑LHC will increase the integrated luminosity of the current LHC by a factor of ten, producing unprecedented volumes of data (on the order of several exabytes over its lifetime). This major evolution makes the development of new AI and algorithmic approaches essential, particularly for event reconstruction and physics analysis. Scientific objectives include Higgs boson physics, searches for physics beyond the Standard Model, heavy‑flavour physics and QCD phenomenology.
Within this context, Irfu is developing a foundation model trained on large volumes of simulated and/or real data from the ATLAS, CMS and LHCb experiments to enable efficient transfer learning (fine‑tuning) for a wide range of downstream physics tasks. This approach is directly inspired by the success of large language models (LLMs) and vision foundation models.
You will join a multidisciplinary team composed of particle physicists, scientific computing engineers and machine learning researchers.
