Software Development Engineer , DynamoDB Index, Search and Storage

Senior Software Development Engineer Software Development Engineer, DynamoDB Search and Indexing Amazon DynamoDB is a serverless, distributed NoSQL database that delivers single-digit millisecond performance at virtually any scale. The DynamoDB Search and Indexing organization is building native search capabilities that allow customers to perform vector similarity search, full-text search, and hybrid search across their operational data. We are looking for a Senior Software Development Engineer to help design and build the distributed indexing, retrieval, and ranking infrastructure behind these capabilities. You will work on problems at the intersection of databases, distributed systems, information retrieval, and machine-learning infrastructure. The role includes designing vector and text-indexing architectures that operate across partitioned datasets; integrating approximate nearest-neighbor algorithms and inverted indexes with DynamoDB's storage and query systems; and building hybrid retrieval that combines semantic similarity, lexical relevance, and structured filtering. You will help determine how search indexes are created, maintained, rebuilt, rebalanced, and recovered while the underlying DynamoDB data continues to change. You will also shape query planning, distributed execution, relevance ranking, and result aggregation while delivering predictable performance across latency, throughput, recall, freshness, availability, and cost. This is an opportunity to shape new DynamoDB capabilities from foundational architecture through customer launch and operation at DynamoDB scale.
