LOOKING FOR CANDIDATES PREFFRERABLY FROM GAMING BACKGROUND

- System Architecture & Performance Engineering

  • Architect a unified client-side architecture that shares core trading logic, order-book management, and binary data parsers across Web (Wasm), Native iOS/Android, and Cross-Platform frameworks (Flutter / React Native).
  • Design zero-copy data ingestion pipelines for streaming WebSockets using binary protocols (Protobuf, FlatBuffers, or SBE) that parse and process market depth off the main UI/JavaScript/Dart threads.
  • Build hardware-accelerated charting and order-book rendering systems utilizing Canvas, WebGL/WebGPU (Web), Impeller/Skia (Flutter), and Metal/Vulkan (Native Mobile) to guarantee deterministic 120 FPS performance.
  • Manage memory and thread optimization by eliminating garbage collection pauses, UI thread blocking, and frame drops through memory pooling, background Web Workers/Isolates, and lock-free data structures.

- Standards, Governance & Technical Leadership

  • Establish and enforce comprehensive coding standards, design patterns, and code quality benchmarks\\ across Web, Native, React Native, and Flutter codebases.
  • Define architectural criteria for feature development using Flutter/React Native versus native modules (Swift/Kotlin) or C++ for maximum throughput.
  • Define and monitor performance SLAs across all platforms.
  • Implement automated performance testing pipelines that enforce strict thresholds for bridge overhead, memory usage, bundle sizes, and rendering latency.
  • Lead mentorship and hiring efforts, elevating the engineering team's technical capabilities and conducting technical evaluations for new hires.

- UI/UX Collaboration & Human Factors

  • Collaborate with UI/UX designers to translate complex market data (Level 2/3 order books, depth charts, position logs) into high-density, ergonomic web and mobile layouts.
