Company mission
To ensure that anyone anywhere can tell their stories.
Role
Who you are
- 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
- We’re committed to creating a space where our employees can bring their full selves to work and have equal opportunity to succeed. So regardless of race, gender identity or expression, sexual orientation, religion, origin, ability, age, veteran status, if joining this mission speaks to you, we encourage you to apply
Desirable
- Experience building AI-powered or LLM-integrated mobile experiences
- Background in in-app purchases (StoreKit / Google Play Billing)
What the job involves
- 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
Our take
Runway is revolutionising content creation and video editing with machine learning, harnessing the expansive capabilities of web-based tools. At the forefront of this transformation, the startup offers a suite of AI-powered editing tools tailored for designers, artists, and creators, setting itself apart in an industry dominated by enterprise-focused software solutions.
The company has rapidly gained recognition among some of the world's largest brands, including R/GA, New Balance, Google, and IBM, by appealing directly to creative professionals. This approach has not only solidified Runway's position in the market but also facilitated its integration into the design curricula of esteemed institutions such as NYU, RISD< and MIT.
In a testament to its growing influence and success, Runway achieved unicorn status in 2023 following a landmark $100M funding round, which valued the company at $1.5B. This milestone not only reflects investor confidence but also positions Runway to expand its innovative tools and further democratise access to advanced video editing capabilities globally.
