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, on an airplane, or at a 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 such as 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.
Role Description
Help us ignite the future of edge data synchronization as a Senior Software Engineer at Ditto! We are seeking someone to work directly within the core of Ditto’s data sync platform and help shape our database replication systems. Design mission‑critical data sync protocols that work in challenging environments to deliver on Ditto’s goal of a high performance, self‑healing, and reliable mesh. Work with a remote team, manage your own time, and tackle interesting problems.
What You’ll Be Up To
- Work with product managers and other engineers to help design and evolve the core technology.
- Troubleshoot production issues and design future remediations to ensure a high‑performance, self‑healing mesh.
- Relentlessly optimize for efficient bandwidth usage and reliable data transfer between peers.
- Build robust data sync technologies using:
- 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.
- Content addressing and retrieval in a dynamic mesh with no central coordination.
- Low‑level I/O optimization across Ditto’s supported platforms.
What Helps You Thrive
- Excellent Rust experience, either professionally or through personal projects or open‑source work.
- Excitement to learn the fundamentals of distributed file storage and sync systems.
- BSc in Computer Science or equivalent.
- Strong operating systems knowledge covering system calls, concurrency primitives, memory mapping, durability, and write ordering.
- Good algorithmic reasoning and data structure knowledge, especially in probabilistic structures, graph theory, and computational complexity.
- Willingness to travel internationally once a quarter for team get‑togethers and design sessions.
- Strong written communication skills for async collaboration and documentation.
Great‑to‑Haves
- Experience with networking on multiple platforms, including mobile OSes such as iOS and Android.
- Understanding of networking and routing protocols (TCP, UDP, BGP, OSPF, etc.) and core concepts.
- Experience with lightweight formal methods such as property testing and model checking.
- Experience with modern networking advancements such as fountain codes, QUIC, and noise encryption.
- Mobile development experience.
