Company mission
To expand the internet via software enabling devices to synchronise data in realtime, even where the internet doesn't reach.
Role
Who you are
- Fluency in Rust including proficiency with:
- Asynchronous programming, including cancel safety
- Concurrency primitives
- Multithreading
- Strong type system knowledge and applicability of this knowledge to idiomatic Rust design patterns (e.g. typestate, builder, etc)
- Experience using low-level platform tooling
- OS APIs
- File system
- OS-level concurrency
- Blocking & non-blocking IO, including modern scalable I/O event notification mechanisms (e.g. epoll, kqueue etc.)

- Strong data structure & algorithms knowledge
- Unit and integration testing, with bonus points for lightweight formal methods such as property testing
Desirable
- Experience with SQLite, LMDB, OPFS, IndexedDB
- Deep knowledge or experience implementing database internals such as indexes, storage engines, etc
- Experience implementing blob storage including topics such as cloud object storage, content addressing & deduplication, file systems, etc
- Working knowledge of CRDTs
- Experience with distributed systems
- Experience working in C or C++ codebases
What the job involves
- The Storage team is responsible for the way on-device data is organized across all supported platforms from mobile devices to web clients
- This team will work closely with the Data Sync Team which is responsible for moving the data through the mesh, the Query Team which implements our query language DQL, and the Core Library Team which is responsible for providing a library to our SDKs developers that works on all platforms
- Break ground on greenfield projects, and design new features
- Support the data storage systems across a wide variety of environments, from mobile devices to small servers to web clients
- Collaborate closely with product and neighboring engineering teams to build end-to-end customer-facing features
- Design and build storage interfaces and features that support nearly all Ditto features, including:
- Key-Value stores
- Blob storage
- File system access
- Indexing
- Performance tuning
- Build & maintain native storage implementations across a variety of platforms including Windows, iOS, macOS, linux, and web using operating system specific functionality where appropriate
Our take
While it's convenient to assume that all the data an app needs is always located in a single place, the reality is more messy. Multi-cloud platforms, IoT devices with varied or limited connectivity and even smartphones can hold necessary data for many applications. The problem for developers is how to tame, access and use this data. Ditto exists to fix this, providing a distributed database that pulls and synchronises data from edge devices and the cloud.
Able to operate even in locations without internet, using peer-to-peer WiFi, Bluetooth and wired networks to pull data together, it provides a layer of infrastructure which is increasingly required as IoT picks up steam. However, it is not the only entrant in this growing market, and faces competition from the likes of Whalesync, PieSync and Grouparoo.
While most of these companies provide the same kind of functionality, Ditto's large and growing customer base in the tens of thousands (including the likes of the US Air Force, Lufthansa and Japan Airlines) indicates that its product is a strong competitor in this space. It has also attracted the attention of investors, most recently closing a hefty Series A round. It intends to use this funding to almost double its headcount and to focus on commercializing its product.
