Position : AI Engineer (Conversational Analytics & GenAI Systems)

Location : Bengaluru, India

About the Product :

You will work on IRISS's conversational analytics platform, a GenAI-powered chatbot that

transforms natural language queries into validated, compliant, and tenant-aware SQL and

visual insights. This platform enables users to ask business questions like “Show me last

and reports generated safely through AI-driven data pipelines.

Our AI stack :

Interprets user intent using LLMs.
Generates validated, policy-compliant SQL.
Executes and visualizes data with context and feedback loops.
Powers a RAG-based (Retrieval-Augmented Generation) framework integrated with

existing IoT and analytics microservices

Job Overview :

You will design, develop, and maintain the AI chatbot platform that serves as the

intelligence layer for our SaaS ecosystem. This includes architecting end-to-end

conversational pipelines from LLM prompt design to data retrieval, integrating vector-

based search systems and RAG pipelines into our service mesh, leveraging AWS AI / ML and

orchestration services such as Bedrock, Kendra, OpenSearch, Lambda, ECS, and S3 to build

scalable and secure infrastructure, and partnering with full-stack and front-end engineers

to embed AI features directly into user workflows
