Full-Stack Engineer (High-Performance Web Systems)

What You Will Do

• Legacy Transformation: Reverse-engineer complex business logic from C# WPF systems and architect modern, scalable equivalents in a web-native environment.
• Data Pipeline Engineering: Architect and optimize the end-to-end WebSocket pipeline, implementing advanced techniques like binary serialization (Protobuf), message routing, and bounded channel queuing.
• High-Frequency UI: Develop real-time data visualizations and grids that handle thousands of updates per second with zero UI lag using Web Workers and custom rendering strategies.
• Infrastructure Collaboration: Partner with trading and infra teams to bridge the gap between low-latency backend services and the end-user experience.
• Quality & Resilience: Establish automated testing frameworks for real-time systems and provide tier-2 production support to ensure 24/7 system reliability.
