Amazon; Seattle, Northern (WA, KY); Hybrid; USD 144,000 - 194,000; Full time

Job summary

Amazon is seeking a Software Development Engineer II for the Personalization team to design and build scalable knowledge systems that power AI-powered memory across contexts. You will translate research ideas into production, delivering prototypes in partnership with Applied Scientists and engineering leadership.

You will work on end-to-end systems handling real-time streams and batch data, optimizing retrieval, and building APIs to access structured knowledge.

Qualifications

• 3+ years of non-internship professional software development experience.
• 2+ years in design or architecture (design patterns, reliability and scaling) of new and existing systems.
• Experience programming with at least one software programming language.
• Experience with knowledge graphs, vector databases, or information retrieval systems.
• Familiarity with LLM integration patterns, prompt engineering, or agentic AI frameworks.

Responsibilities

• Design and build highly scalable distributed systems that capture, structure, and retrieve knowledge in real time across diverse data sources.
• Implement intelligent retrieval and ranking capabilities that match intent to relevant knowledge with sub-second latency.
• Create APIs and data models that enable AI systems to access structured memory across multiple contexts and domains.
• Develop and optimize pipelines for processing both real-time event streams and batch data into durable, retrievable knowledge representations.
• Build systems that respect temporal decay, relevance boundaries, and access controls to ensure knowledge stays current and appropriate.
• Collaborate with Applied Scientists to integrate novel approaches to knowledge extraction and pattern recognition into production infrastructure.
• Work on innovative solutions for cross-domain knowledge reconciliation — connecting insights that span different tools, teams, and workflows.
• Contribute to the development of feedback loops that allow the system to compound its value with every interaction processed.
