Job Description
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, 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.
Benefits We Offer
- Competitive salaries and stock options
- Medical, dental, vision, life, and disability coverage
- Flexible spending account (FSA)
- Generous, flexible vacation policy
- 401(k) plan with employer match
Come join our remote team and help shape the future of real-time data sync across every edge device!

Verify Employer Thoroughly
Research the company's identity thoroughly before applying. Check for a professional website with contacts, active social media, and LinkedIn profiles. Verify details across platforms and look for reviews on Glassdoor or Trustpilot to confirm legitimacy.
Never Pay to Get a Job
Legitimate employers never require payment for applications, training, background checks, or equipment. Always reject upfront payment requests or demands for bank details, even if they claim it's for purchasing necessary work gear on your behalf.
Safeguard Your Personal Information
Protect sensitive data like SSN, bank details, or ID copies. Share this only after accepting a formal, written job offer. Ensure it's submitted via a secure company system or portal, never through insecure channels like standard email attachments.
Scrutinize Communication & Interviews
Watch for communication red flags: poor grammar, generic emails (@gmail), vague details, or undue pressure. Be highly suspicious of interviews held only via text or chat apps; legitimate companies typically use video or phone calls.
Beware of Unrealistic Offers
If an offer's salary or benefits seem unrealistically high for the work involved, be cautious. Research standard pay for similar roles. Offers that appear 'too good to be true' are often scams designed to lure you into providing information or payment.
Insist on a Formal Contract
Always secure and review a formal, written job offer or employment contract before starting work or sharing final personal details. Ensure it clearly defines your role, compensation, key terms, and conditions to avoid misunderstandings or scams.
