About the Role

We're looking for an experienced AI/LLM Engineer to design, build, and deploy production-ready AI agents powered by Large Language Models (LLMs). The ideal candidate has hands-on experience building intelligent conversational agents using ChatGPT/OpenAI APIs, implementing Retrieval-Augmented Generation (RAG), integrating external tools, and developing real-time voice AI applications.

This role requires someone who has shipped AI products—not just experimented with prompts.

Responsibilities

• Design and develop AI agents using OpenAI GPT models and other leading LLMs
• Build conversational AI systems capable of reasoning, tool use, memory, and workflow automation
• Develop voice AI agents with real-time speech-to-text and text-to-speech capabilities
• Integrate AI agents with APIs, CRMs, databases, and third-party services
• Implement Retrieval-Augmented Generation (RAG) using vector databases
• Optimize prompts, agent workflows, latency, and model performance
• Develop multi-agent systems when appropriate
• Deploy AI applications to cloud environments
• Monitor, evaluate, and improve AI performance in production
• Collaborate with product and engineering teams to deliver scalable AI solutions

Required Qualifications

• 3+ years of software engineering experience
• 2+ years building applications with Large Language Models
• Strong experience with:
• OpenAI API / ChatGPT
• GPT-4.x and newer models
• AI agent frameworks (LangGraph, LangChain, OpenAI Agents SDK, CrewAI, or similar)
• Python
• REST APIs
• JSON
• Git
• Experience implementing:
• Function calling / tool calling
• RAG architectures
• Vector databases (Pinecone, Weaviate, Chroma, Qdrant, FAISS, etc.)
• Prompt engineering
• Conversation memory
• Experience deploying AI applications to AWS, Azure, or Google Cloud
