Australia beBeeFrontEnd Full time $160,000 - $200,000
Overview

Twine is seeking a skilled front-end developer to refine and accelerate our React-based user interface. Our application is functional but requires focused upgrades to responsiveness, rendering efficiency, and UX clarity across real-time market views.

As a key member of our development team, you will be responsible for auditing the current React codebase, implementing performance optimizations, and refactoring state management for responsiveness and clarity.

Responsibilities
  • Audit the current React codebase to identify rendering bottlenecks, excessive re-renders, and inefficient state flows.
  • Implement performance optimizations (memoization, virtualization, code-splitting, selective re-renders) to improve perceived and actual speed.
  • Refactor state management for responsiveness and clarity; improve data handling for streaming/rapid updates (e.g., WebSocket-driven UI).
  • Enhance core views such as market overview, opportunity listings, order/book tables, and execution history for legibility and speed.
  • Introduce or refine design system components (buttons, tables, modals, toasts) to ensure consistency and accessibility.
  • Improve charting and tabular data experiences (pagination, sorting, filtering, column pinning) with minimal latency.
  • Establish metrics and profiling routines (React Profiler, performance marks, Core Web Vitals proxies) and create a lightweight performance budget.
  • Optimize network usage for real-time data: request batching, debouncing, stale-while-revalidate patterns where appropriate.
Requirements
  • Strong proficiency with React in production environments; experience improving performance in data-intensive apps.
  • Experience with state management patterns (Context, Redux Toolkit, Zustand, or similar) and query/data libraries (React Query/SWR).
  • Experience with data visualization and complex tables (e.g., Recharts, Victory, ECharts, TanStack Table, ag-Grid).
  • Competence in UI/UX fundamentals, responsive design, and accessibility (WCAG-aware).
  • Comfort with tooling: Vite/webpack, ESLint/Prettier, Jest/RTL, and React Profiler/DevTools.
  • Ability to work independently on a part-time, remote contract; clear communication and structured delivery.
  • Bonus: knowledge of financial/trading UI patterns (order books, spreads, latency cues) and basic understanding of arbitrage concepts.
