Job description
Structured overview of role & requirements
About This Role
- Design and build an Azure-native LLM gateway in C# with features like intelligent routing, fallback/load balancing, rate limiting, token-quota enforcement, semantic caching, and centralized API key management.
- Implement observability and governance layers including request/response tracing, logging, token and cost metering, and latency dashboards using Azure Monitor and related tooling.
- Lead end-to-end technical delivery on client engagements including architecture proposals, hands-on builds, demos, production readiness, and packaging reusable engineering assets for redeployment.
Minimum Requirements
- 12-15+ years of deep C#/.NET production-grade API/service development experience including async patterns, dependency injection, and testing discipline.
- Hands-on Azure platform expertise: Azure API Management with GenAI/LLM policies, Azure OpenAI/AI Foundry, Azure Monitor/Application Insights, Key Vault, and service hosting via Azure Functions/App Service or AKS.
- Working knowledge of LLM gateway and observability platforms such as LiteLLM, Langfuse, Portkey, or Kong AI Gateway to translate their concepts for Azure/C# implementation.
- Experience with Microsoft Agent Framework or demonstrated capability with Semantic Kernel and/or AutoGen, involving multi-agent orchestration and advanced agent communication protocols.
Ideal Candidate Profile
- Senior engineer capable of independently architecting and delivering complex Azure-based AI gateway solutions without a large platform team.
- Experienced client-facing solution engineer skilled in translating ambiguous business requirements into demoable AI agentic scenarios and defending design decisions live.
- Strong practitioner of multi-agent orchestration and AI tooling integration, familiar with Microsoft Agent Framework or its predecessors, oriented towards reusable engineering asset creation.
