The Role
Own end-to-end mobile development across multiple React Native/Expo apps. Build shared infrastructure (notifications, analytics, media, subscriptions), integrate AI/LLM features, architect scalable codebases, improve CI/CD and tests, collaborate with product/design, and set engineering patterns alongside the CTO.
Summary Generated by Built In
Join the core engineering team and own the mobile layer across our live product portfolio. This isn't a single-product role - you'll work across multiple creator-led apps and build the shared mobile infrastructure that powers all of them.
Tasks
* Own end-to-end mobile development across iOS and Android on our React Native / Expo stack
* Build and maintain shared infrastructure: push notifications, analytics, media streaming, subscription flows
* Architect scalable codebases that can grow with the product and the user base
* Integrate AI-powered features - streamed LLM responses, generative content, intelligent notifications
* Collaborate with product and design to ship high-quality, pixel-perfect experiences
* Contribute to CI/CD pipelines, automated testing, and code quality standards
* Work closely with the CTO - set engineering patterns future hires will learn from
Requirements
* 5+ years building and shipping production React Native apps on iOS and Android
* Deep expertise with Expo (managed and bare workflows), React Navigation, and state management
* Experience with Reanimated, Skia, and Apollo Client
* Solid understanding of push notifications (APNs / FCM), background processing, and app lifecycle
* Hands-on experience with Supabase or similar BaaS, and PostgreSQL
* Familiarity with RevenueCat or other in-app subscription platforms
* Strong TypeScript skills and a high bar for code quality
* Comfortable working async in a remote-first team with strong written communication
Benefits
* Live products with real users - not internal tools or greenfield prototypes
* Remote-first, async culture with high autonomy
* Fast-moving team that ships constantly - no endless planning cycles
* Equity-aligned model: we build products we co-own with creators
