Role Summary We are seeking a Senior AI Engineer to design, build, and scale a production-grade Generative AI and Data Platform on AWS. The role focuses on enabling LLM-powered capabilities through vector search, graph-based knowledge systems, and governed data pipelines. The ideal candidate will own end-to-end delivery across the AI lifecycle, including:

Data ingestion and knowledge curation Embeddings and retrieval systems Backend services and APIs CI/CD pipelines and deployment

This role will closely partner with product and engineering teams to operationalize AI capabilities in externally facing applications and drive evolution toward agentic AI systems.

Key Responsibilities 1. GenAI Enablement & Integration

Build and operationalize LLM-powered applications using:

Retrieval-Augmented Generation (RAG) Embeddings pipelines Prompt orchestration and evaluation frameworks

Design and implement vector search systems using Amazon OpenSearch Develop graph-based knowledge systems using Amazon Neptune for relationships, lineage, and explainability Integrate supporting infrastructure:

Amazon ElastiCache (Redis) for session state and caching DynamoDB for scalable, low-latency data access

Implement agentic workflows using frameworks such as:

LangGraph, AutoGen, CrewAI (or equivalent)

Integrate with LLM frameworks like:

LangChain, LlamaIndex (tool calling, retrieval orchestration, context management)

Define standards for:

Tool integration Context-sharing patterns (MCP-style designs)

Evaluate LLM models and retrieval strategies across:

Latency Cost Accuracy Context limitations
