Flutter Developer

Why This Role Exists

What You'll Own

• Core trading screens:

  watchlists, stock pages, option chain, order entry, positions, holdings and P&L, built for speed and one-handed use

• Real-time data layer:

  WebSocket streams for live prices, order updates and alerts, with reconnection logic, subscription management and smooth handling of patchy mobile networks

• AI on mobile:

  the chat interface where traders ask questions and get answers as live cards, charts and widgets

• Charts and visualisation:

  fast, readable charts and payoff diagrams that hold up on smaller screens

• App performance:

  smooth scrolling on long lists, low startup time, sensible memory and battery use, and no dropped frames during market hours

• Release and quality:

  clean builds and releases on Play Store and App Store, crash monitoring, and working closely with QA on every release

What We're Looking For

• 5-7 years building mobile apps, with at least 2 years of production Flutter and Dart. Apps you've shipped that are live on both stores
• Solid state management at scale with Riverpod or Bloc. You know why you picked one over the other
• Real-time experience: WebSockets, streams and keeping the UI responsive while data updates every second
• A clear understanding of how Flutter renders, and the habit of profiling before guessing at a slowdown
• Comfort with platform channels when you need native Android or iOS features
• Design sense. You can take a Figma file and make it feel better on an actual device

Bonus Points

• Experience building a trading, broking or fintech app
• You trade yourself
