Job Description

• Own technical direction and architecture for PVP’s mobile trading experience. • Build high-performance React Native UI for real-time trading, analytics, and social features at scale. • Craft smooth, interruptible animations, gesture-driven motion systems, and tactile feedback that feel premium and effortless. • Translate Figma design systems into reusable RN component libraries that scale. • Work closely with designers to iterate on UI/UX in Figma and code, ensuring pixel-level fidelity. • Design a robust, resilient real-time data pipeline for mobile using modern TypeScript state management and WebSockets. • Bridge native modules (Swift/Kotlin) where performance, animations, or haptics demand it. • Partner with backend engineers to optimize API and data-layer efficiency for bandwidth and latency. • Profile and eliminate performance bottlenecks—achieve consistent 60 FPS across devices and platforms. • Ship production-ready code with monitoring, debugging, and iterative tuning post-launch.

Job Requirements

  • 5+ years of hands-on React Native experience shipping production apps built with TypeScript.
  • Deep knowledge of React Native Reanimated (v2/v3) for gesture-based motion and animations.
  • Experience using RN Skia, Lottie, or similar low-level rendering systems for custom charts, visuals, or effects.
  • Native iOS (Swift / SwiftUI) or Android (Kotlin) experience is a bonus.
  • Experience at high-quality consumer-grade or trading apps (e.g., Discord, Shopify, Rainbow Wallet, Robinhood, Coinbase, or similar).
  • Contributions to open-source React Native libraries or animation frameworks is a bonus.
  • Experience designing motion or animation systems used across a scaled mobile app.

Benefits

  • Remote (EU, LATAM, or North America preferred with 5–6 hours EST overlap)
