How You'll Contribute
Build real, production AI features that power Network Solutions and other Newfold products—clean APIs, reliable agent workflows, and pragmatic RAG that measurably improves SMB customer experiences.

What You Will Do

• Ship async APIs in Python (FastAPI) or .NET/C# with DI, typing, tests, and containers.
• Build agentic workflows (tool-calling, structured outputs) using Semantic Kernel or LangChain/LangGraph.
• Build high throughput and scalable MCP servers for agents
• Implement RAG : stand up retrieval using Azure AI Search or a vector DB (pgvector/Qdrant/Chroma) and wire it into generation.
• Integrate multiple LLMs behind a lightweight gateway (e.g., LiteLLM) for A/B, fallbacks, and spend tracking.
• Observe & improve latency/cost/quality using OpenTelemetry + Langfuse traces/evals.
• Collaborate cross-functionally with product/design; write crisp design docs; participate in code reviews.

The must-haves

• 3+ years backend engineering (Python or .NET/C#) with production APIs, testing, and CI/CD.
• 1+ year hands-on GenAI building apps with LLMs (prompting, tool calling, structured outputs).
• Shipped at least one RAG feature (search + generate) using Azure AI Search or a vector store (e.g., pgvector).
• Solid SQL/Postgres skills (ORM + migrations), Docker fluency, and clear written/spoken communication.
• Comfortable with 8:30 AM–12:30 PM ET overlap.

Nice to have

• Langfuse dashboards, OTEL traces, cost guardrails for LLM calls.
• LiteLLM gateway experience (routing, budgets).
• Queueing/streaming (RabbitMQ/Kafka), basic eval pipelines, or exposure to MCP-style plugins in agent frameworks.
