Original job description

English section of this bilingual listing.

Your team's dynamic:

We're looking for a Senior Software Developer specialized in C# and REST API design. Your mandate will be twofold: build the company's new integration services in ASP.NET Core and Azure, and modernize an existing set of APIs built on WCF and .NET Framework 4.8. You'll play a key role in service architecture, migration strategy, and technical leadership within the team. This role is for someone equally comfortable reading legacy code and designing new services from scratch.

Your day at a glance:

Design and develop RESTful APIs in C# / ASP.NET Core (.NET 8+)
Analyze existing WCF and .NET Framework 4.8 services, then plan and carry out their migration to REST APIs hosted in Azure
Maintain and evolve legacy services during the transition, keeping both worlds running side by side without disruption for consumers
Design integration processes using Azure Logic Apps, Azure Functions, Service Bus, and API Management
Define API standards: OpenAPI/Swagger contracts, versioning, backward compatibility, error handling

What makes you a great fit:

5+ years of C# / .NET development experience, including: ASP.NET Core Web API and REST principles, and .NET Framework 4.8 and working knowledge of WCF (SOAP, WSDL, bindings, .svc services)
Azure Logic Apps, Azure Functions, Service Bus
Hands-on experience migrating or rebuilding existing services toward modern architectures
Strong knowledge of OAuth, API security, and JSON/XML transformations
Solid grasp of SQL Server and Entity Framework
Experience with CLI tools, Postman, Swagger
CI/CD implementation with Azure DevOps
Fluent in French and English, both verbal and written (this role requires interaction with our international collaborators and customers)
XXXX
XXXX
Experience with microservices or large-scale enterprise systems
Experience building EDI services (cXML, X12, AS2)
Familiarity with Microsoft Dynamics 365 / Dataverse and the Power Platform
Front-end development in JavaScript / TypeScript

Let's talk perks!

Attractive compensation package
Training Tuition Reimbursement Program
Work-life balance with a flexible working schedule
Onsite fitness facility with personal trainer, and multiple wellness and health workshops

La dynamique de votre équipe :

Nous recherchons un(e) développeur(euse) logiciel sénior spécialisé(e) en C# et en conception d'API REST. Votre mission sera double : développer les nouveaux services d'intégration de l'entreprise sous ASP.NET Core et Azure, et moderniser un ensemble d'API existantes basées sur WCF et .NET Framework 4.8. Vous jouerez un rôle clé dans l'architecture des services, la stratégie de migration et le leadership technique au sein de l'équipe. Ce poste s'adresse à une personne aussi à l'aise avec la lecture de code hérité qu'avec la conception de nouveaux services à partir de zéro.

Votre journée en un coup d'oeil :

Concevoir et développer des API RESTful en C# / ASP.NET Core (.NET 8+)
Analyser les services WCF et .NET Framework 4.8 existants, puis planifier et mener à bien leur migration vers des API REST hébergées sur Azure
Assurer la maintenance et faire évoluer les services existants pendant la transition, en garantissant le fonctionnement parallèle des deux environnements sans interruption pour les utilisateurs
Concevoir des processus d'intégration à l'aide d'Azure Logic Apps, d'Azure Functions, de Service Bus et d'API Management
Définir les normes relatives aux API : contrats OpenAPI/Swagger, gestion des versions, rétrocompatibilité, gestion des erreurs
Appliquer des modèles de conception sécurisés (OAuth 2.0, Entra ID, gestion des API)
Contribuer à l'automatisation DevOps via Azure DevOps (pipelines CI/CD, stratégies de déploiement)
Accompagner les développeurs et contribuer à l'élaboration des normes techniques et aux revues de code

Ce qui fait de vous un excellent candidat :

Au moins 5 ans d'expérience en développement C# / .NET, notamment : ASP.NET Core Web API et principes REST, .NET Framework 4.8 et connaissance pratique de WCF (SOAP, WSDL, liaisons, services .svc)
Azure Logic Apps, Azure Functions, Service Bus
Expérience pratique de la migration ou de la refonte de services existants vers des architectures modernes
Solides connaissances en matière d'OAuth, de sécurité des API et de transformations JSON/XML
Maîtrise approfondie de SQL Server et d'Entity Framework
Expérience avec les outils CLI, Postman et Swagger
Mise en œuvre de la CI/CD avec Azure DevOps
Maîtrise du français et de l'anglais, à l'oral comme à l'écrit (ce poste nécessite des interactions avec nos collaborateurs et clients internationaux)

Un atout si vous avez :

Certifications Microsoft (par exemple : Développeur Azure, Architecte de solutions Azure)
Expérience dans le domaine des microservices ou des systèmes d'entreprise à grande échelle
Expérience dans la mise en place de services EDI (cXML, X12, AS2)
Maîtrise de Microsoft Dynamics 365 / Dataverse et de la Power Platform
Développement front-end en JavaScript / TypeScript

Voilà ce que nous offrons !

Régime de rémunération attrayant
Programme de remboursement des frais de formation
Équilibre entre vie professionnelle et vie privée grâce à un horaire de travail flexible
Repas subventionnés à notre incroyable Bistro (Les Cordons Bleus)
Café et fruits gratuits à volonté
Espace de stationnement gratuit pour tous les employés
Centre de conditionnement physique sur place avec entraîneur personnel, ainsi que plusieurs ateliers de santé et de bien-être

Nous savons que la diversité des parcours et des expériences apporte une grande valeur à nos équipes. Même si vous ne cochez pas toutes les cases nous vous encourageons à postuler - votre profil pourrait nous surprendre!
