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
