Senior Software Engineer, Data Sync

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.

Ditto work: our data sync engine (including novel replication algorithms and CRDT libraries), our query engine (DQL—a SQL-like language designed for CRDT-based documents), and our embedded database performance. Together, these three workstreams form the technical heart of Ditto’s product.

From day one, you will own delivery across these workstreams, working closely with senior engineers who are deep domain experts, and partnering with product managers to translate customer needs into a focused, well-prioritized roadmap.

Operating in our async-first culture, you will drive execution through clear written communication, ruthless prioritization, and a relentless focus on shipping. This is a people management role—our Staff+ engineers own the technical depth, and your job is to make them fast, focused, well-supported. Your background in this domain will help guide the team and ensure we’re building in the right direction. Your years of delivering database or adjacent products mean you think about performance, quality gates, and rollout strategies for critical infrastructure.

At Ditto, we know game-changers don’t always come wrapped in a “perfect” resume. Years of experience? Every single bullet point checked? Meh. That’s not what drives us.
