The Role
Own end-to-end mobile development for multiple React Native/Expo apps on iOS and Android. Build shared infrastructure (push notifications, analytics, media streaming, subscriptions), architect scalable codebases, integrate AI/LLM features, collaborate with product and design, contribute to CI/CD and automated testing, 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
