Senior React Native Engineer @ UK Startup - 45MN Indonesian Rupiah

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

Affinity Labs is a full-stack, AI-driven software builder that partners with content creators to co-found and scale software businesses. We take products from idea to launch, then keep operating and improving them - so creators can focus on their content and community while still owning meaningful upside.

Our model is built for a world where software is getting cheaper to build, but distribution is harder to earn. Creators already have trust and attention, but most don’t have the time, technical skills, or the right partners to turn audience demand into a real product. We solve that by combining a repeatable product engine (reusable templates + AI-assisted development) with creator-led distribution.
