Le/la candidat(e) participera pleinement à la compréhension du métier, à la construction du vocabulaire partagé avec les équipes fonctionnelles, à l'identification des agrégats et invariants du domaine, ainsi qu'à la définition de frontières applicatives cohérentes — avant de transformer ces décisions en solutions logicielles de niveau production. La mission couvre l'ensemble du cycle : découverte du domaine métier, conception technique, développement frontend et backend, tests automatisés, mise en production, supervision et maintien en conditions opérationnelles.\nMissions principales\nConcevoir et développer des API métier et des produits stratégiques utilisés à l'échelle du Groupe\n\nModéliser des processus métier complexes selon une approche pragmatique du Domain-Driven Design\n\nDéfinir les périmètres fonctionnels (bounded contexts), les modèles de données, les contrats d'interface et les patterns d'intégration\n\nContribuer activement aux choix technologiques et à l'évolution de l'architecture\n\nInfluencer les décisions produit et techniques en collaboration avec ingénieurs, architectes et product managers\n\nDévelopper des fonctionnalités sur l'ensemble de la stack : interface moderne, services .NET, API REST, architecture événementielle et infrastructure cloud-native\n\nPorter la responsabilité complète du cycle de vie applicatif (conception → build → run) : développement, tests, déploiement, supervision, amélioration continue\n\nAccompagner la montée en compétences des profils plus juniors via guidance technique et revues de code\n\nProfil recherché\nCompétences techniques requises\nForte expertise en C# / .NET (API REST, Entity Framework, xUnit), Git et Azure DevOps (pipelines YAML), sur des services distribués en production\n\nBonne maîtrise de TypeScript et d'un framework frontend moderne (React, Angular ou Vue.js)\n\nPratique confirmée du Domain-Driven Design : vocabulaire métier partagé, agrégats, invariants, périmètres fonctionnels, capacité à traduire des besoins métier ambigus en modèles techniques clairs\n\nConception et maintien d'API bien documentées, versionnées et à contrats stables\n\nBonne compréhension des principes d'architecture logicielle : séparation des responsabilités, modularité, clean architecture, inversion de dépendances\n\nExpérience solide des tests automatisés sur toute la chaîne (unitaires, intégration, API, composants, contrats, end-to-end) avec xUnit, NSubstitute, SonarQube (ou équivalent), ainsi que des outils frontend comme Jest, Vitest, Testing Library, Cypress ou Playwright\n\nExpérience de l'architecture événementielle et de la communication asynchrone (Kafka ou équivalent)\n\nCapacité à raisonner sur la propriété des données, la cohérence, l'idempotence, l'auditabilité, la gestion de la concurrence et des modes de défaillance\n\nExpérience en environnement Cloud Azure (Container Apps, Key Vault, CosmosDB, Azure SQL, Azure Monitor/App Insights), conteneurisation et pratiques cloud-native\n\nOutils CI/CD et Infrastructure as Code : Azure DevOps, GitHub Actions, Terraform\n\nCapacité à diagnostiquer et résoudre des incidents de production complexes, du frontend à l'infrastructure\n\nParticipation active aux décisions d'architecture et à des revues de code exigeantes","description_format":"text","description_chars":3293,"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":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-07T13:04:23Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long
