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.

• 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.
