Description

Amazon's AGI Information is seeking an exceptional Software Development Engineer to drive advancements in the Amazon Knowledge Graph (AKG) Construction and Retrieval infrastructure. AKG is re-inventing knowledge graphs for the LLM-era, optimizing for LLM grounding and enabling agentic AI systems that require real-time knowledge retrieval. AKG serves as the foundational knowledge layer for Nova and Alexa+, providing structured, factual information that grounds LLM responses and powers autonomous agent decision-making across Amazon surfaces.

As a member of the AKG Interfaces team, you will have the opportunity to work on interesting problems with immediate customer impact. The team is addressing challenges in automating gap detection, data ingestion, fact verification, query optimization, entity resolution, and building scalable APIs that serve billions of requests from agentic systems.

Key job responsibilities

Build a scalable information grounding infrastructure that provides grounding evidence to multiple Amazonian experiences and agentic AI systems. Grounding large language models (LLMs) and AI agents ensures that their interactions with users are informed, relevant, consistent, and trustworthy. It ensures accuracy and relevance by providing context-specific responses and mitigating the risk of generating false information through techniques like Retrieval-Augmented Generation (RAG).

Design & Write code: Write code primarily in Java and design scalable, fault tolerant and distributed applications running on AWS technology. Leverage state of the art AWS resources in the development of a scalable web grounding service for LLM based applications.

Troubleshoot and fix operational problems: You will work with systems engineers to troubleshoot operational problems and fix them. If you are so inclined, you will also automate troubleshooting procedures and write tools. And when the issues concern specific customers, you will also have the opportunity to talk to them and understand their space better.
