The role focuses on designing, building, and scaling production-grade LLM applications using advanced Python, generative AI orchestration, multi-agent workflows, and Retrieval-Augmented Generation (RAG) systems.

Requirements

Advanced, production-level proficiency in Python, including asyncio, design patterns, profiling, and testing.
Hands-on production experience with one or more of LangChain, LangGraph, LangSmith, or Deepagents.
Strong working knowledge of RAG pipelines, prompt engineering strategies, and vector database integration.
Familiarity with major LLM providers, including OpenAI, Anthropic, or open-source models through Hugging Face or Ollama.
Familiarity with function-calling and tool-use architectures.
Experience with Git, CI/CD pipelines, Docker, and cloud environments such as AWS, GCP, or Azure.

Responsibilities

Design, implement, and optimize RAG architectures, including custom chunking, hybrid search, embedding optimization, and reranking.
Develop stateful multi-agent systems and autonomous workflows using frameworks such as LangGraph and Deepagents.
Use LangChain for LLM integration and LangSmith for tracing, evaluation, debugging, and production pipeline performance monitoring.
Write clean, modular, efficient, and maintainable Python code using asynchronous programming, strict typing, and robust error handling.
Connect LLM agents and workflows with external data sources, enterprise APIs, vector databases, and developer tooling, including Model Context Protocol integrations where applicable.
Optimize token usage, latency, and operational costs while maintaining response quality and accuracy.
