About the Role

We are seeking a Senior/Principal AI Engineer to design and build production-grade Agentic AI and Generative AI applications that enable Client's executives to interact with operational data through a conversational interface.

The ideal candidate will have strong experience building LLM-powered applications, AI agents, RAG solutions, tool-calling workflows, and data-grounded AI systems, with a strong focus on accuracy, trust, scalability, and production readiness.

  • Design and develop Agentic AI / LLM-based applications for enterprise use cases.
  • Build conversational AI experiences that allow users to query complex operational data using natural language.
  • Develop agent workflows using frameworks such as LangGraph and LangChain.
  • Design single-agent and multi-agent architectures based on business and technical requirements.
  • Build RAG and retrieval workflows using vector search, embeddings, and PostgreSQL/pgVector.
  • Develop controlled tool-calling and SQL-based data retrieval workflows.
  • Implement mechanisms to prevent hallucinations and ensure responses are grounded in authoritative data.
  • Design validation processes for data availability, freshness, accuracy, and provenance before generating responses.
  • Integrate AI agents with enterprise data sources and APIs.
  • Work with AWS-based data and AI infrastructure.
  • Evaluate and optimize LLM application performance, including latency, token usage, cost, and response quality.
  • Design approaches for managing long conversational context, intent routing, and context isolation.
  • Implement real-time status/progress updates for long-running AI workflows using technologies such as WebSockets or Server-Sent Events.
  • Establish evaluation frameworks and metrics for AI accuracy, grounding, hallucination, and overall system quality.
  • Collaborate with product managers, data engineers, architects, and business stakeholders.
  • Lead technical discussions, architecture decisions, code reviews, and mentor other engineers.
Required Technical Skills
  • Strong experience with Generative AI / LLM applications
  • Hands-on experience with Agentic AI
  • LangGraph and/or LangChain
  • Python & AWS
  • RAG / Retrieval-Augmented Generation
