L'objectif est de libérer le métier de l'obsolescence d'un socle historique AS400 dont la fin de licence est fixée à 3 ans, en basculant vers une architecture cible moderne, résiliente et hautement évolutive. Dans le cadre d'une démarche Design-to-Cost et frugale, le programme s'appuie sur une plateforme agentique de pointe (OpenHands).

Contrôle Technique & Lecture de Code (Poste MOE) : Inspecter, relire et valider le code produit automatiquement par la plateforme agentique (stack Java / Micronaut). Détecter les éventuels écarts entre les spécifications et le code généré, puis ajuster les prompts et la documentation pour corriger la plateforme. Participer à la conception de la couche de données et aux requêtes sous PostgreSQL. Définir et exécuter les cas de tests fonctionnels et de recette en parallèle de la rédaction des spécifications. 3. Démarche Agile & Contribution à l'Architecture : Participer activement aux cérémonies Agile (Scrum) et apporter votre vision lors de la phase de cadrage d'architecture en cours. Collaborer étroitement avec les équipes Front-Office (Pega) et les experts de la gouvernance informatique.
