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.

We’re looking for a Senior Software Engineer to join Ditto’s Data Sync team, one of our core engineering teams, and help keep mission-critical work moving when connectivity disappears. Our technology lets edge devices access the data they need and share updates as connections come and go, so applications keep working when a device goes offline.

In this role, you’ll help shape the foundation behind that experience. It’s a rare and deeply interesting challenge: making software dependable in a world that’s distributed, unpredictable, and often offline. Your work will help customers build applications that don’t have to wait for a connection to do what matters. You’ll be part of a core technical team changing what’s possible at the edge.

• Prior hands-on experience with CRDTs, distributed systems, or offline-first data synchronization.

• Experience building software or integrating with embedded databases or data sync platforms.

• Basic networking knowledge: IPv4, TCP, UDP, Bluetooth Low Energy, mesh networking concepts.

• Experience with property-based testing, model checking, or other lightweight verification techniques.

• A track record of open-source contributions in relevant ecosystems.

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.

What does matter?

• Grit.

• Curiosity.

• Adaptability.

• And a genuine spark for what we’re building.

So if you’re fired up about our mission but not sure you tick every box - hit that apply button anyway. Use your application to show us how you’ll make an impact here.

We’re always on the lookout for exceptional humans who want to grow, stretch, and build something meaningful with us.
