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

We're looking for a Senior Software Engineer to work directly within the core of Ditto's data sync platform and help shape our database replication systems. You'll design mission-critical data sync protocols that work in challenging environments, delivering on Ditto's goal of a high-performance, self-healing, and reliable mesh.

Your written design docs and code reviews matter just as much as live collaboration, and regular meetups and customer visits bring the team together around real-world problems. If you're passionate about owning large cross-platform projects end-to-end, improving developer experience at scale, and building the systems that power mission-critical applications, this is the role for you.

Responsibilities

• Work with product managers, public sector and commercial customers, and other engineers to help design the future of data sync and mesh network technology.
• Troubleshoot production issues, and design future remediations to deliver on Ditto's goal of a high performance, self-healing, and reliable mesh.
• Relentlessly optimize to ensure efficient bandwidth utilization and reliable data transfer between peers.
• Use both industry standard and novel techniques to build robust data sync technologies:
  • Checksumming, content-defined chunking, Merkle trees, erasure codes, and data deduplication with content-addressable storage.
  • Modern probabilistic data structures such as bloom filters and cuckoo filters.
  • Highly concurrent async programming in Rust.

Requirements

• Grit
• Curiosity
• Adaptability
• A genuine spark for what we’re building

The Benefits of Building with Us

We offer competitive salaries and meaningful equity. We believe everyone on the team should have a stake in what we’re building. Benefits vary by region to make sure you're covered in the ways that matter most. In the US, that includes health, dental, vision, life, and disability insurance, plus a 401(k) and flexible spending accounts.

Regardless of where you live, everyone at Ditto can utilize flexible time off. And while we work remotely, our Atlanta office is always open if you ever want a place to work or meet up with teammates.
