AI Engineer (RAG & Multi-Agent Systems)

Job Description

We are looking for an experienced AI/LLM Engineer to design, build, and maintain intelligent applications powered by Large Language Models (LLMs), embeddings, similarity search, vector databases, and multi-agent architectures.

The ideal candidate will build real-time AI systems such as chatbots, semantic search engines, recommendation systems, document intelligence platforms, MCP servers, and autonomous multi-agent workflows capable of tool usage and inter-agent communication.

You will own the end-to-end lifecycle of AI pipelines including data ingestion, embedding generation, vector storage, retrieval, LLM response orchestration, tool invocation, agent communication, and automated decision workflows.

Experience: 23 Years

Location: Bangalore

Employment Type: Full-Time

Key Responsibilities

• Design and implement embedding pipelines for text, documents, images, and structured data.
• Build and optimize semantic search and similarity search systems using vector databases.
• Integrate and manage vector databases such as:
• Pinecone, Weaviate, Milvus, FAISS, Chroma, OpenSearch Vector Engine, etc.
• Develop LLM-powered applications for:
• Chatbots
• Q&A systems
• Recommendation engines
• AI agents and automation workflows
• Implement RAG (Retrieval Augmented Generation) pipelines with hybrid retrieval and reranking.
• Design and develop multi-agent architectures (planner-executor, supervisor-worker, tool-using agents).
• Build and deploy MCP (Model Context Protocol) servers to expose tools, memory, and external systems to LLM agents.
• Develop structured agentic workflows using frameworks like LangGraph, Strands, or similar orchestration engines.
• Implement multi-agent communication using A2A (Agent-to-Agent) protocols for collaborative reasoning and task execution.
• Design tool-calling pipelines and function-calling integrations.
• Fine-tune prompt strategies, memory handling, and system prompts for optimal LLM performance.
• Integrate LLM providers such as:
• 
  
• OpenAI, Azure OpenAI, Anthropic, Google Gemini, Meta LLaMA, Mistral, etc.
• Build APIs and microservices for AI systems using:
• Python / Java / Node.js / Spring Boot / FastAPI
• Implement similarity scoring, ranking, filtering, and metadata-based retrieval.
• Monitor, optimize, and scale vector search performance.
• Optimize LLM cost, latency, caching, and response validation strategies.
• Implement AI safety mechanisms, hallucination reduction, guardrails, and evaluation pipelines.
• Work closely with product, frontend, and data teams.
• Deploy AI workloads on AWS, Azure, GCP, or OCI.

Maintain CI/CD pipelines for AI services.
