Senior Mobile App Developer (React Native)

Job Description

Ratio 16 is not a traditional software agency; we are a high-velocity Digital Factory. We build and scale proprietary SaaS platforms, complex multi-vendor engines, and engaging consumer apps.

We operate on a strict "16:1 Efficiency Ratio." By equipping our engineering floor with high-end workstations and premium AI co-pilots, we empower one elite architect to output the work of an entire traditional team. If you hate corporate red tape, slow deployment cycles, and outdated legacy code, you belong here.

We are urgently looking for a Senior React Native Developer who can architect, build, and deploy world-class iOS and Android applications from a single codebase.

You will not be working in a silo. You will act as the critical bridge between our UI/UX Designer (who will hand you complex, premium Figma prototypes) and our Senior Full-Stack Engineer (who will provide you with secure, headless APIs). You must know how to manage complex state, handle offline data syncing, and ensure 60fps animations, all while using AI to accelerate your boilerplate coding.

Requirements

  • Key Responsibilities:
  • Cross-Platform Architecture: Design and build highly scalable, responsive, and
  • performant mobile applications for both iOS and Android using modern React Native (and Expo, where applicable).
  • API Integration & Security: Consume RESTful APIs securely. Handle token-based
  • authentication, refresh tokens, and encrypted local storage.
  • Complex State & Offline Sync: Architect robust state management (using Zustand or Redux Toolkit) and implement offline-first capabilities so the apps function flawlessly during network drops.
  • Pixel-Perfect UI & Animation: Translate complex, creative Figma designs from our UI/UX team into flawless mobile interfaces. Implement smooth 60fps animations and gestures using React Native Reanimated.
  • Native Bridging & Hardware: Integrate device-level features like Geolocation, Camera, Push Notifications, and background tasks. Write or tweak native code (Swift/Kotlin) when the JavaScript bridge isn't enough.
  • AI-Augmented Development: Aggressively utilize AI tools (Antigravity, GitHub Copilot, Cursor) to write tests, generate boilerplate, and debug complex native build errors rapidly.
  • App Store Deployment: Manage the complete CI/CD pipeline for mobile. Handle the deployment, versioning, and compliance processes for both the Apple App Store and Google Play Store.
  • Qualifications:
  • Availability: Candidates who can join immediately or at short notice will be given absolute priority.
  • Bachelor degree in Computer Science, Software Engineering, or a related field.
  • Experience: 3+ years of heavy, verifiable professional experience building
  • production-ready apps in React Native.
  • JavaScript/TypeScript Mastery: Deep understanding of modern ES6+ and TypeScript.
  • You must understand the React lifecycle, hooks, and memory leak prevention inside and out.
  • Backend Synergy: You must have a strong understanding of how backend databases and queues work, so you can effectively communicate your data needs to our Full-Stack engineer.
  • Payment Integration: Experience integrating mobile payment gateways and managing in-app purchases or subscription routing.
  • Clean Code & Agile: Strong grasp of software design patterns, clean code principles, and rapid sprint delivery.
  • Excellent Problem Solving: The ability to independently debug deep Xcode/Gradle build errors without panicking.
