United States onlyAbout 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.
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.
As a Flutter Staff Software Engineer on the SDKs Team, you will:
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.
What you’ll need:
- 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
Nice to Haves:
- 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.
