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
- 3+ years building production software with a track record of shipping reliable code in a team setting
- Fluency in Dart and comfort designing idiomatic, null‑safe APIs
- Hands‑on Dart FFI experience building bridges to native code
- Strong testing discipline (unit, integration, CI pipelines)
- Familiarity with CI/CD tools such as GitHub Actions or CircleCI
- Clear, concise communication—especially in async, written form
Desirable
- Experience building or maintaining SDKs, libraries, or developer tools in Rust or other languages
- Familiarity with one or more of our consumer languages (Kotlin, JavaScript/TypeScript, Swift)
- Background in peer-to-peer or real-time synchronization systems
- Prior work with performance profiling or memory-constrained environments
What the job involves
- As a Staff Software Engineer (Flutter SDK) on the SDK team, you will set the technical vision and drive the end‑to‑end delivery of Ditto’s Flutter package—empowering developers to synchronize data in real‑time across Android, iOS, desktop, and web
- You’ll design idiomatic, null‑safe Dart APIs, architect cross‑platform plugin modules, and build reliable bridges between Dart and Ditto’s native core using Dart FFI and platform channels
- From day one, you will own architecture decisions, performance profiling, and release automation while mentoring engineers and shaping best practices across the mobile organization
- Working closely with product, design, and backend teams, you will translate developer‑experience goals into intuitive APIs and high‑performance code
- You’ll collaborate with customers and support engineers to diagnose integration issues, optimize for battery, memory, and start‑up time, and iterate rapidly on feedback
- Operating in our async‑first, globally distributed culture, you will craft clear design docs, conduct thorough code reviews, champion rigorous testing and observability, and foster a culture of collaboration and continuous improvement
- Implement and enhance Flutter SDK features
- Deliver scoped ticket work: add new API methods, improve existing functionality, and fix defects under the direction of senior engineers
- Write reliable tests
- Author unit and integration tests to validate Flutter logic and interoperability, ensuring code quality and preventing regressions
- Own quality from test to release – Build unit/integration tests, profile performance, automate releases, and uphold robust observability
- Participate in code reviews
- Contribute thoughtful feedback on pull requests, learn from review comments, and uphold team coding standards
- Collaborate cross-functionally
- Work with product, QA, and support teams to clarify requirements, reproduce customer issues, and verify fixes
- Produce and maintain documentation
- Write clear README updates, code examples, and API reference snippets that help internal and external developers onboard quickly
- Communicate progress and blockers
- Proactively share status updates in standups and async channels; escalate challenges early to keep projects on track
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.
