About The Position

Client is seeking a .NET full-stack developer with a back-end focus (C#) for its Extranet applications, working in an environment that combines a modern stack (Azure, integration components) with legacy systems. The core of the role is server-side development; front-end work primarily involves integration rather than building rich user interfaces. Requirements regarding user session management (tokens), public-facing applications, IIS, and Windows Server—combined with the project's high priority—point to a candidate comfortable with external-facing systems and access security. Integration technologies (Kafka, Kong, BizTalk) indicate a context of inter-system data exchange. The mandate specifies no minimum experience or seniority level. Profiles to exclude: pure front-end developers, middleware specialists lacking a .NET application development background, and legacy developers with no Azure experience.

Requirements

• C# .NET back-end development
• Front-end integration for exposed applications
• User session and token management
• Azure cloud services
