Python AI Infrastructure Engineer

Build production-grade AI infrastructure with Python and FastAPI at EPAM Systems, supporting enterprise knowledge systems and reliable retrieval. Work across backend services and observability.

As a Python AI Engineer, you will evolve a Confluence-focused RAG chatbot into a broader agentic knowledge system. You will use Pydantic, SQLAlchemy async, asyncpg, and modern retrieval pipelines. Your work will support ingestion, evaluation, agent runtime capabilities, and shared conversational platform primitives.

Key Responsibilities:

• Architect backend services with Python 3.11 and FastAPI
• Design retrieval trade-offs involving quality, latency, cost, and safety
• Build agent memory boundaries, tool sandboxing, permissions, and budget controls
• Improve grounding, failure analysis, and citation enforcement
• Create observability using OpenTelemetry, Prometheus/Grafana, Docker, Helm, and GitHub Actions

Requirements:

• Strong hands-on Python experience in infrastructure-heavy environments
• Experience building CLI tools with Python, Golang, or Rust
• Hands-on LangGraph, LangChain, pgvector, and retrieval pipeline experience
• Experience designing LLM evaluation frameworks and regression detection
• Strong Docker, Helm, GitHub Actions, and Kubernetes workflow experience

Apply Python, retrieval, agent infrastructure, and observability expertise to dependable enterprise AI systems at EPAM Systems.
