About The Position

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. 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.

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 Haves

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

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
