AI Engineer building generative-AI applications end to end: LLM apps, RAG pipelines, and agentic workflows (MCP tools, vector search, prompt engineering) from PoC through deployment and support. Core stack is Python, LLM providers (Azure OpenAI/OpenAI/Claude/Gemini), and agent frameworks like LangChain/LangGraph, plus REST APIs, SQL, and CI/CD.
About the role
Develop and enhance AI/Generative AI applications using Large Language Models (LLMs). Design and implement RAG pipelines for intelligent knowledge retrieval and question-answering solutions. Build AI agents and agentic workflows for reasoning, planning, tool usage, and task automation. Develop end-to-end AI solutions from PoC and prototyping through implementation, testing, deployment, and support.
