## Description

Prêt à transformer la vision en action ? Magellan est un Groupe international de Conseil en management et de Technologies. Notre force réside dans notre capacité à activer à la fois expertise métier et maîtrise technologique pour accompagner les entreprises et les organisations publiques dans toutes leurs transformations. VISION IN ACTION Dans un environnement où les mutations s’accélèrent, les organisations doivent en permanence réinventer leurs modèles pour rester compétitives. Pour y répondre, nous accompagnons nos clients de la définition de leur stratégie à sa mise en œuvre opérationnelle, en combinant expertise métier, maîtrise technologique et capacité d'exécution. Rejoindre Magellan, c’est intégrer un collectif de 6 700 talents engagés, unis par une même exigence : accompagner les enjeux de nos clients dans toute leur complexité pour construire des solutions concrètes et activables au plus près des réalités du terrain. Magellan figure parmi les entreprises où faire accélérer sa carrière (Classement LinkedIn Top Companies 2026). Au sein de la business line Strategic Solutions & Services, le pilier Omnichannel Interactions accompagne les organisations dans la transformation de leur expérience client. Il mobilise l’expertise métier, les technologies de centres de contact et l’intelligence artificielle pour concevoir des interactions plus fluides, personnalisées et performantes. En intégrant l’IA au cœur de nos solutions, nos équipes conçoivent des solutions permettant aux organisations d’automatiser les parcours clients complexes tout en maintenant une supervision humaine là où elle est essentielle. The opportunity Multi-agent architectures are no longer science fiction: they already handle millions of customer interactions (voice, email, chat, social media), automatically processing simple cases and intelligently escalating complex ones to human advisors. In this fast-moving environment, We are expanding our Agentic AI platform to fully integrate voice, chat, and orchestration capabilities into our CCaaS solution. The ambition is clear: build a truly unified, AI-native contact center that elevates both customer experience and agent productivity, while positioning us at the forefront of the next wave of customer engagement. Day-to-day responsibilities You contribute to the full development and maintenance lifecycle of our Agentic Platform, actively participating in project delivery phases. You specify, design, and develop APIs and Web services, while writing and maintaining robust unit and functional tests. You identify, challenge, and analyze both functional and technical requirements to deliver value-driven solutions. You work on a microservices-based architecture deployed on our Sovereign Cloud or on the Google Cloud Platform, leveraging a modern and diverse tech stack — Java/ Kotlin, Angular, Spring, Docker, Kubernetes, and more — within a cutting-edge engineering environment built on Clean Architecture, design patterns, and dependency injection. You apply engineering best practices: code reviews, merge requests, automated testing, and continuous integration (GitLab CI). You build and extend the harness of our AI Agent, enhancing state-of-the-art LLMs with custom capabilities (connectors, RAG) to deliver high-quality support powered by internal knowledge base. You drive continuous improvement of our processes through an SRE-oriented approach, industrializing and scaling the solution. Who are we looking for We are looking for people capable of driving positive change, moving forward, and showing the way — passionate individuals with a positive attitude and a thirst to learn and progress. In practice, this means: You have a global vision and end-to-end technical understanding of an IT service: application, underlying infrastructure, and related dependencies. You have solid knowledge of Cloud computing and a strong sensitivity to DevOps and FinOps practices. You have hands-on experience with Agentic technologies, prompt
