Dot NET Back End Developer

NET Back End Developer

We are looking for a NET Back End Developer to build the reliable services, serverless logic, APIs and integration endpoints behind an Enterprise AI platform. You will develop secure steering and telemetry APIs, durable workflows, integration services and governed MCP endpoints that expose enterprise data and tools safely to agents and user-facing applications.

• Build ASP.NET Core services and Azure Functions using modern C# (.NET), including APIs for steering, telemetry, audit, tool execution, and agent runtime support.
• Implement secure APIs behind Entra and API Management, including pause, resume, kill, override, redirect controls and other operational commands required by the ACC.
• Develop durable orchestrations for long-running agent loops: serverless workflows, retries, idempotency, circuit-breakers, and reliable data access patterns.
• Design and build integration services and MCP servers that expose entity data and tools safely to agents through governed endpoints.
• Implement OAuthOIDC on-behalf-of flows, scoped credentials, short-lived tokens, least-privilege access and secure tool argument schemas.
• Integrate with legacy and modern enterprise systems using APIs, Logic Apps, web Methods, .NET, Type Script, Python SDKs and event integration patterns where appropriate.
• Emit audit logs, application telemetry, trace IDs and operational metrics for every meaningful system and agent action.
• Work closely with AI engineers, cloud Dev Ops, data developers, front-end engineers, governance and delivery teams to move services from sandbox to production.

• Strong hands‑on C# and .NET 8/9 experience, including ASP.NET Core REST APIs, Azure Functions isolated worker and secure API design.
• Experience with distributed systems patterns, async programming, retries, idempotency, circuit‑breakers, background jobs, durable workflows and operational reliability.
• Experience with Azure API Management, Microsoft Entra, OAuth/OIDC, MSAL, managed identities, Key Vault and role‑based access control.
• Practical experience with data access using EF Core and at least one of Azure SQL, PostgreSQL, Cosmos DB, Redis or comparable data stores.
• API and integration engineering experience, including enterprise integration patterns, API contracts, versioning, contract testing and secure connectivity.
• Understanding of MCP (Model Context Protocol) or willingness to build MCP endpoints using .NET, Type Script, Python SDKs as governed integration contracts for agents.
• Strong testing, debugging, performance tuning, logging, and CI/CD collaboration habits.

• Semantic Kernel for .NET, Dapr, gRPC, durable agent-loop hosting or high‑reliability service design experience.
• Experience with Azure API Center, Logic Apps, web Methods, event‑driven integration, iPaaS or complex enterprise integration environments.
• Experience building services that support AI agents, tool calling, HITL workflows, audit‑ledger operation or observability‑heavy platforms.
• Familiarity with sovereign cloud, government, regulated environments, security reviews, data residency and least‑privilege design.
• Experience collaborating directly with external entity IT teams, security reviewers or platform governance stakeholders.
