Runway에서 React Native 기반의 AI 창작 도구를 함께 개발할 모바일 엔지니어를 찾습니다. 5년 이상의 모바일 개발 경력과 TypeScript 숙련도가 필수이며, 제품의 기획부터 배포, 모니터링까지 전 과정을 주도적으로 이끌어갈 분을 환영합니다. 생성형 AI 기술을 모바일 환경에 최적화하여 사용자에게 혁신적인 경험을 제공하는 것이 핵심 과제입니다.
We are building AI to simulate the world through merging art and science.
We believe that world models are at the frontier of progress in artificial intelligence. Language models alone won’t solve the world’s hardest problems – robotics, disease, scientific discovery. Real progress requires models that experience the world and learn from their mistakes, the same way that humans do. And this kind of trial and error can be massively accelerated when done in simulation, rather than in the real world.
World models offer the most clear path to general-purpose simulation, changing how stories are told, how scientific progress is made and how the next frontiers of humanity are reached.
Our team consists of creative, open minded, caring and ambitious people who are determined to change the world. We aspire to continuously build impossible things and our ability to do so relies on building an incredible team. If you are driven to do the same, we'd love to hear from you.
*Open to hiring remote across North America + Europe — we also have offices in NYC, San Francisco, and Seattle
We are looking for a Mobile Engineer to join our team and help build the next generation of AI-powered creative tools on iOS and Android. You will own key product surfaces in our React Native app, from generative video workflows and an AI assistant chat experience, to real-time media playback, ad/storyboard creation tools, and character interactions powered by LiveKit. Ownership here goes beyond writing code: you will instrument features for measurement, manage feature-flag rollouts, monitor for stability and usability post-launch, and use those insights to help inform what we build next. We are seeking engineers with strong mobile fundamentals, a high bar for UX quality, and the drive to see features through from prototype to production and beyond.
Our mobile app is built with React Native and Expo in TypeScript. Navigation is handled by React Navigation (native-stack, drawer, modals), and we rely on TanStack Query alongside React Context patterns for state management. The UI layer leans on Reanimated, Skia, and Expo modules for rich animations, graphics, and media handling (video playback, cropping, image manipulation, camera). We integrate LiveKit for real-time video, Mixpanel for analytics, and Sentry for error monitoring. Builds and OTA updates ship through EAS (Expo Application Services), with CI on GitHub Actions.
Build and ship product features in a React Native app that puts cutting-edge generative AI video models directly in users' hands
Own features through their full lifecycle: instrument analytics, manage feature-flag rollouts, monitor stability and usability post-launch, and surface learnings that inform next steps
Help keep the mobile app up to date with the latest AI capabilities and contribute to a continuous stream of experiments aimed at improving retention and engagement
Own complex, media-rich UI surfaces: video playback and cropping, asset galleries, multi-step storyboard/ad-builder workflows, and interactive prompt interfaces
Bring strong UX taste to every feature, ensuring interactions feel polished, intuitive, and native to each platform
Develop and maintain an AI-powered chat assistant experience with streaming responses, tool-use handlers, and rich message rendering
Integrate real-time audio/video features using LiveKit for character call experiences
Collaborate with backend and web engineers to design and consume APIs that power generative AI tools, asset management, billing, and in-app purchases
Improve app performance, startup time, animation smoothness, and reliability across iOS and Android
Participate in release engineering, managing EAS builds, OTA updates, and App Store / Play Store submissions
5+ years of industry experience in mobile engineering, with production experience on React Native (TypeScript), iOS (Swift/UIKit or SwiftUI) or Android (Kotlin)
A high-ownership mindset: you care about what happens after code merges, from rollout and monitoring to measuring impact and iterating
A keen eye for UX quality and attention to detail in interactions, animations, and visual polish
Experience with mobile navigation patterns, complex state management, and performance optimization on resource-constrained devices
Familiarity with media handling on mobile: video playback, image manipulation, camera, or audio
Experience shipping apps through the App Store and/or Google Play, including familiarity with build tooling, code signing, and OTA update mechanisms
Comfort working with RESTful APIs and integrating third-party SDKs (analytics, auth, payments)
Ability to rapidly prototype solutions and iterate under tight product deadlines
Humility and open-mindedness; at Runway we love to learn from one another
Experience building AI-powered or LLM-integrated mobile experiences
Background in in-app purchases (StoreKit / Google Play Billing)
