Il recherche un Data Scientist senior pour une mission de 3 mois au cœur de l'optimisation de ses parcours clients digitaux.\nVous aurez un rôle clé dans la conception de modèles analytiques avancés. Ils serviront à mieux comprendre le comportement des utilisateurs, à détecter les frictions, à améliorer la conversion et à mesurer la performance réelle des actions marketing et opérationnelles.\nVos principales missions :\nSegmentation comportementale : clustering des utilisateurs à partir de la navigation, des réservations et des usages digitaux ; identification des personas, des micro-segments, des intentions et des points de friction.\n\nSystèmes de recommandation : conception de recommandeurs hybrides (collaboratif, contenu, séquentiel) pour personnaliser les contenus et les services à valeur ajoutée proposés.\n\nModèles prédictifs : prédiction de conversion, de churn et de complétion du funnel ; prévision des volumes par étape du parcours ; scoring d'intention et de drop-off.\n\nAttribution multi-touch : modèles de Markov (1er et 2e ordre) et valeurs de Shapley pour mesurer le poids de chaque point de contact (email, WalkMe, AB Tasty, notifications, pages clés) et calculer le ROI des actions CJO.\n\nIA générative et LLM : développement de solutions capables d'interpréter automatiquement les résultats analytiques (tests A/B, conversions, parcours) et de générer des recommandations pour orienter les décisions.\n\nIndustrialisation : passage des POC Jupyter à des modules Python propres, modulaires et testés, et à des pipelines Dataiku/Snowflake documentés et ordonnancés.\n\nUne mission particulièrement intéressante pour un profil qui veut associer data science avancée, IA générative et impact business direct sur les parcours clients.\nProfil recherché\nData Scientist confirmé à senior, avec une solide expérience de l'analyse de parcours clients digitaux et du marketing analytics.
