• A high-ownership mindset
• A keen eye for UX quality and attention to detail
• Experience with mobile navigation patterns and complex state management
• Familiarity with media handling on mobile
• Experience shipping apps through the App Store and/or Google Play
• Comfort working with RESTful APIs and integrating third-party SDKs
• Ability to rapidly prototype solutions
• Humility and open-mindedness

Requirements

• Build and ship product features in a React Native app
• Own features through their full lifecycle
• Help keep the mobile app up to date with the latest AI capabilities
• Own complex, media-rich UI surfaces
• Bring strong UX taste to every feature
• Develop and maintain an AI-powered chat assistant experience
