Company Description


Miracle is a next-generation cryptocurrency front-end trading terminal designed for retail & professional traders. We are building a high-performance, visually stunning interface that bridges the gap between complex blockchain data and seamless user experience.


Role Description


We are seeking a Senior React Native Developer who lives at the intersection of high-end UI/UX and financial engineering. You will be responsible for the architecture and implementation of our mobile trading application. You will be building real-time data visualizations, complex order-entry systems for perpetual futures, and a highly polished interface.


Key Responsibilities



  • Performance Engineering: Develop and maintain high-performance React Native applications with a focus on low-latency data updates and smooth interactions.

  • UI/UX Craftsmanship: Implement sophisticated UI features, ensuring pixel-perfect execution of transparency, blurs, and fluid animations.

  • Protocol Integration: Work closely with our backend team to integrate Web3 providers, APIs, and real-time WebSocket feeds.

  • Native Optimization: Write Custom Native Modules (Java/Kotlin and Objective-C/Swift) when React Native’s bridge isn’t enough to achieve the desired performance.

  • Trading Lifecycle: Build and optimize the end-to-end trading flow, from wallet creation to complex order execution and position monitoring.


Qualifications



  • Technical Mastery Deep React Native Expertise: 4+ years of professional experience building complex, production-grade mobile apps. You should be an expert in the bridge, Reanimated, and optimizing the render cycle.

  • Native Best Practices: Strong understanding of iOS (Human Interface Guidelines) and Android (Material Design) best practices, specifically regarding “Liquid Glass” effects and haptic feedback.

  • Crypto & Domain Expertise Perpetual Futures Knowledge: You are not just a developer; you are a trader. You understand funding rates, leverage, maintenance margin, and liquidation mechanics.

  • Trading Terminal Experience: Prior experience building trading interfaces or financial dashboards for large web3 companies is highly preferred.


Soft Skills



  • Problem Solver: Ability to debug complex performance bottlenecks in a remote, fast-paced environment.

  • Attention to Detail: An obsession with “the feel” of an app, ensuring every gesture and transition is fluid and intentional.
