Job description

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
