Remote Graduate Ios Developer Jobs in Georgia (NOW HIRING)

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 Senior SDK Engineer on Ditto's SDKs team, you will own the developer experience for our React Native SDK-one of the most popular ways developers integrate Ditto's real-time, offline-first synchronization into their mobile applications. You'll design and ship APIs that feel natural to React Native developers while navigating the complex boundary between JavaScript and native code.
React Native SDK work is inherently cross-platform. When things go wrong, the root cause often lives deep in native Android or iOS code, not in JavaScript. That's why we're looking for someone who brings strong Android development experience alongside their React Native expertise. You'll need to be comfortable diving into Kotlin, reading JNI stack traces, and debugging issues that span from a TypeScript hook all the way down to our Rust core.
Our React Native SDK bridges to native Android and iOS implementations, which in turn connect to Ditto's Rust core through FFI layers. You'll work across this entire stack-designing ergonomic JavaScript APIs, implementing native modules, and collaborating with platform SDK owners to ensure consistent behavior. When a customer reports an issue, you'll be the one tracing it through React Native's bridge, into native code, and potentially down to the Rust layer.
From day one, you'll own the full development lifecycle: designing intuitive public APIs, implementing robust native bridges, writing comprehensive automated tests, and collaborating with our Release team to ship reliable updates. You'll work directly with customers and support to diagnose integration issues, optimize performance on constrained devices, and turn field feedback into product improvements.
You'll join a small, globally distributed team that values trust, clear communication, and continuous improvement. In our async-first culture, your written design docs and code reviews carry as much weight as synchronous meetings, and occasional offsite gatherings bring us together to share learnings and strengthen our bond.
What You'll Do
Own the React Native SDK. Drive the design, implementation, and ongoing maintenance of Ditto's React Native SDK, ensuring it meets our high standards for reliability, performance, and developer ergonomics.
Craft idiomatic APIs for React Native developers. Expose public interfaces that feel natural-hooks, TypeScript types, familiar async patterns, and clear error handling-while abstracting away the complexity of native bridges and synchronization internals.
Build and maintain native bridges. Implement safe, efficient bindings between JavaScript and native code via JSI, TurboModules, or the classic bridge, handling threading, serialization, memory management, and error propagation.
Debug across the full stack. Trace issues from JavaScript through the React Native bridge, into native Android and iOS code, and potentially into our Rust core. You'll need to be equally comfortable in Chrome DevTools and Android Studio.
Work with other SDK owners. Work closely with the engineers who own our native Android, iOS, and Rust SDKs to ensure the React Native SDK stays in sync with platform capabilities and benefits from shared improvements.
Develop comprehensive test suites. Write and automate unit, integration, and end-to-end tests-including native interop scenarios and multi-device synchronization tests-to continuously validate SDK functionality and guard against regressions.
Integrate with CI/CD pipelines. Collaborate with the Release and QA teams to embed your tests into our continuous integration workflows, monitor release quality, and iterate rapidly on customer feedback.
Partner with customer support. Triage and resolve customer-reported integration issues, debug edge-case failures in the field, and feed learnings back into product and engineering roadmaps.
Mentor and evangelize best practices. Share your expertise in React Native architecture and cross-platform SDK design through design reviews, documentation, and coaching to level up the team.
What You'll Need
5+ years of professional mobile development experience with a proven track record of delivering production-quality applications or libraries.
Deep expertise in React Native internals. Hands-on experience with the native bridge architecture, JSI, TurboModules, or Fabric. You understand how JavaScript communicates with native code and have debugged issues that span both worlds.
Strong Android development experience. You've built or maintained Android applications in Kotlin or Java. You can navigate Android Studio, read native stack traces, understand the Android lifecycle, and debug issues at the native layer. This isn't about owning our Android SDK-it's about being effective when React Native issues lead you into native Android code.
Debugging and diagnostic expertise. Ability to trace issues across the JavaScript-native boundary, read stack traces from multiple languages, interpret logs and memory profiles, and isolate problems in complex cross-platform systems.
Test automation and CI/CD fluency. Experience designing and implementing unit, integration, and end-to-end tests for mobile SDKs, and integrating them into automated build and release pipelines.
Excellent communication skills. Strong written and verbal communication to thrive in an async-first, distributed team-drafting clear design docs, participating in code reviews, and coordinating with customers and stakeholders.
Nice to Haves
Native module development experience. You've built custom native modules for React Native that bridge to platform-specific APIs or native libraries, handling threading, serialization, and lifecycle concerns.
iOS development experience. Familiarity with Swift or Objective-C and Xcode, enabling you to debug issues on both mobile platforms when they arise.
FFI and JNI experience. Background building and maintaining Foreign Function Interface bridges, particularly JNI bindings between Kotlin/Java and native code.
Rust development experience. Hands-on work writing, testing, and maintaining Rust codebases, with familiarity in Cargo workflows and idiomatic Rust patterns.
Experience with SDK distribution. Proven ability to publish packages to npm, including versioning, TypeScript declarations, changelog management, and migration guides.
Track record of open-source contributions. Demonstrated involvement in React Native or mobile SDK projects that showcases collaborative development and code quality.
