We are a social trading interface that lets thousands of users long, short, copy- or counter-trade perpetual futures together on the high-throughput Hyperliquid L1 order-book DEX.

We combine real-time market data, social leaderboards and a playful points system to turn trading into a team sport. The platform routinely handles sub-second position updates and billions of dollars of volume every month.

Why this role matters

On mobile, every dropped frame or delayed WebSocket packet is a missed fill. React Native can deliver a native-feeling 60 FPS experience when tuned correctly —but only if we keep latency low through persistent, bi-directional connections. WebSockets are key to that low-latency, real-time flow, and new performance techniques emerging in 2025 let us push React Native even faster. You will own the mobile layer that makes hyper-responsive trading (and clan trash-talk) possible from a phone.

What you'll do

• Build & optimize React Native screens that stream order-book deltas, PnL and clan leaderboards over WebSockets with sub-100 ms budgets.

• Implement a robust real-time data layer (TypeScript, Redux Toolkit Query or equivalent) with offline caching and graceful reconnection logic.

• Bridge native modules when performance demands it, including exposing SwiftUI or UIKit components to React Native on iOS.

• Work closely with backend engineers to define gRPC/JSON payloads and back-pressure strategies that keep mobile sockets thin but dependable.

• Ship monitored code—instrument Sentry and REACT-Native-perf metrics, surface KPIs in Grafana, and own on-call rotations for the mobile stack.

• Collaborate with design to finesse micro-interactions that make the app feel native on both iOS and Android.

What you'll bring

• 4 + years crafting production React Native apps in TypeScript, including experience hitting 60 FPS on complex list and chart views.

• Deep understanding of WebSocket / SSE performance tuning on mobile (heart-beats, batching, incremental JSON, back-pressure).

• Familiarity with native iOS or Android bridges and willingness to dip into Swift / SwiftUI or Kotlin when a pure-JS solution isn't fast enough.

• Comfort profiling CPU, memory and JS-thread contention with Flipper, Xcode Instruments or Android Studio.

• A bias toward shipping measurable improvements every week and iterating with Telegram-first feedback loops.

Bonus points

• Prior work on trading, gaming or other ultra-low-latency apps.

• Experience integrating hardware secure-enclave key custody or wallet libraries.

• Contributions to React Native performance libraries or open-source WebSocket tooling.
