## About the Role

Must-Have

 - 10+ years of software development with strong Python expertise in production environments

 - 2+ years hands-on LLM development (LangChain, LangGraph, or equivalent frameworks)

 - RAG pipeline experience - embeddings, vector search, re-ranking, answer generation

 - LLM APIs - OpenAI Chat Completions, Responses API, streaming, tool calling

 - Async Python - asyncio, httpx, FastAPI

 - Prompt engineering - system prompts, few-shot, structured JSON output

 - Circuit breaker patterns, retry logic, resilient service design

 - PostgreSQL and async ORMs (SQLAlchemy async / Alembic)

 - Git, CI/CD, Docker, Kubernetes basics

 - Strong system design skills - microservices, distributed systems, API design

Nice-to-Have

 - LangGraph StateGraph (conditional edges, node pipelines, compiled graphs)

 - Multi-agent systems - orchestration, routing, RBAC-based access control

 - Langfuse or similar LLM observability (tracing, token usage, latency)

 - WebSocket and SSE streaming protocols

 - Multi-modal AI (vision models, image analysis)

 - Vector databases (OpenSearch, Pinecone, pgvector)

 - AWS services (Aurora PostgreSQL, SSM, IAM, EKS)

 - Telecommunications or field service domain experience

## Description

We are looking for a skilled AI/ML Developer to join our agentic platform team. You will design, develop, and deploy LLM-powered agents and pipelines that directly serve field technicians in production. You will work closely with the platform architect and contribute to the core multi-agent orchestration system.

Key Responsibilities

 - Design and develop LLM-powered agents using LangGraph and LangChain frameworks

 - Build and enhance multi-agent orchestration pipelines with conditional routing, state management, and error recovery

 - Develop RAG pipelines with hybrid search (semantic + keyword), re-ranking, and Reciprocal Rank Fusion

 - Implement tool-calling agents with parallel API execution, sequential enrichment chains, and summarization

 - Build real-time streaming capabilities (WebSocket / SSE) for conversational AI

 - Integrate with Azure OpenAI APIs with circuit breaker patterns and fallback chains

 - Implement prompt engineering and dynamic prompt management (DB-backed with in-memory caching)

 - Design and implement multi-modal AI features (image analysis with vision models)

 - Write production-quality Python code with error handling, logging, observability, and unit tests

 - Participate in code reviews, architecture discussions, and sprint delivery
