En tant qu'AI Engineer, tu seras responsable de la conception et du développement d'applications GenAI, de l'intégration des agents IA aux API et bases de données, ainsi que de la construction et de l'industrialisation des pipelines IA. Tu travailleras dans un environnement exigeant avec des clients prestigieux et bénéficieras d'une culture d'excellence technique et de développement continu.\nMissions\nConcevoir et développer des applications GenAI intégrant des LLM, en exploitant leurs capacités de raisonnement, de génération et d'utilisation d'outils.\nDévelopper des agents IA et des workflows agentiques avec LangChain et LangGraph : orchestration, gestion d'état, mémoire, tool calling, exécution de tâches complexes et gestion des erreurs.\nConcevoir des architectures d'intégration via MCP afin de connecter les agents IA aux API, bases de données, outils et services métiers.\nProfil recherché\n* **Concevoir et développer des applications GenAI** intégrant des LLM, en exploitant leurs capacités de raisonnement, de génération et d'utilisation d'outils.* **Développer des agents IA et des workflows agentiques** avec LangChain et LangGraph : orchestration, gestion d'état, mémoire, tool calling, exécution de tâches complexes et gestion des erreurs.\n* **Concevoir des architectures d'intégration via MCP** (*Model Context Protocol*) afin de connecter les agents IA aux API, bases de données, outils et services métiers.\n* **Développer des API et des services backend en Python** avec FastAPI pour exposer les fonctionnalités IA, gérer les interactions avec les modèles et faciliter leur intégration dans les systèmes existants.\n* **Construire et industrialiser des pipelines IA** : gestion des prompts, intégration des modèles, traitement des données, orchestration des appels LLM et mise en place de mécanismes de fallback.\n* **Déployer et maintenir les solutions en production** en intégrant les composants IA dans des architectures robustes, scalables et observables, avec une attention particulière portée à la performance et à la disponibilité.\n* **Évaluer et optimiser les systèmes GenAI** à travers la conception de jeux de tests, le suivi de la qualité des réponses, la mesure des performances et la maîtrise des coûts d'inférence.\n* **Garantir la sécurité et la fiabilité des applications IA** : gestion des accès, protection des données, validation des entrées et sorties, traçabilité des interactions et maîtrise des risques liés aux agents autonomes.\n* **Contribuer à l'évolution de la plateforme IA** en expérimentant de nouveaux modèles, frameworks et patterns d'architecture, puis en industrialisant les solutions les plus pertinentes.","description_format":"text","description_chars":2734,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"French","level":"Advanced
