Senior Software Engineer, Database

About Ditto: Ditto is redefining how data moves at the edge. Our mission is to make it seamless for developers to build resilient, real-time applications, regardless of network conditions. Whether you're in a stadium, airplane, or remote military base, Ditto's peer-to-peer sync engine ensures devices stay connected and data stays consistent, even without internet. With more than $145 million in funding and trusted by organizations like Chick-fil-A, Delta Airlines, and the U.S. military, Ditto powers mission-critical experiences across aviation, retail, travel, hospitality, defense, and more. As a globally distributed, fast-growing startup, we’re committed to building a diverse and inclusive team that reflects the wide range of perspectives needed to solve the world’s hardest connectivity problems. About the position: The Query Engine and Store team owns the storage and transaction layer at the heart of Ditto’s edge database. This role works with the Ditto Query Language (DQL) and the raw storage engines that underpin our embedded database. You’ll be responsible for backend abstraction, transaction management, concurrency control, CRDT-aware document storage, and blob storage — all designed to run reliably on constrained edge devices like phones, IoT hardware, and ruggedized military systems. This is a uniquely challenging domain: unlike a traditional cloud database, every design decision must account for memory, unreliable storage media, and the need to natively handle Conflict-Free Replicated Data Types (CRDTs) as part of the transaction layer. The storage layer is the foundation that the query engine, sync system, and SDKs all build upon. As a Senior Software Engineer — Embedded Database, you will: - Design and maintain the storage backend abstraction layer and transaction management system that underpins Ditto’s embedded database. - Implement and optimize storage backends (e.g. SQLite, in-memory, RocksDB and other engines), including connection pooling, write ser
