Rust Jobs for Rustaceans

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 Role
As a Senior Rust Engineer at Ditto, you'll work on the systems that millions of devices depend on to stay in sync — reliably, efficiently, and correctly. You'll contribute to one or more of our core areas: the sync engine, networking and transport layer, query execution, storage, or cross-platform SDK delivery. You'll collaborate closely with a distributed team of engineers who hold the bar high and care about getting the details right.

Key Responsibilities:

• Design, build, and maintain performance-critical components of Ditto's core platform, written primarily in Rust
• Contribute to one or more areas: sync protocol, CRDT engine, networking transports (Bluetooth, P2P Wi-Fi, TCP/QUIC), query execution (DQL), or SDK packaging and FFI layers
• Write robust, well-tested code that operates correctly under distributed, offline, and resource-constrained conditions
• Collaborate on API design, making our SDKs a great experience for developers across platforms
• Debug complex concurrency issues, race conditions, and distributed system anomalies in production environments
• Review code thoughtfully, raise the quality of the codebase, and help grow the team through mentorship and documentation

Requirements:

• 4+ years of professional software engineering experience, with at least 2 years writing production Rust
• Deep understanding of Rust's ownership model, type system, async/await, and the broader ecosystem (Cargo, Tokio, Serde, etc.)
• Solid grasp of systems programming fundamentals: memory management, concurrency, networking, and I/O
• Experience working on distributed systems, embedded environments, or performance-sensitive infrastructure
• Strong debugging skills across async, multi-threaded, and cross-platform contexts
• Excellent written communication — we're a distributed team and async clarity matters

Nice to Have:

• Experience with CRDTs, eventual consistency models, or distributed data structures
• Familiarity with P2P networking, Bluetooth LE, QUIC, or mesh networking protocols
• Experience with FFI — exposing Rust to C, Swift, Kotlin, or JavaScript environments
• Background in mobile or embedded systems (iOS, Android, embedded Linux)
• Contributions to open-source Rust projects

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 and San Francisco offices are open if you ever want a place to work or meet up with teammates.

Apply Anyway
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.
