Design and develop backtesting frameworks, research tooling, and simulation environments for quant strategy development
Implement and maintain trading algorithms and execution systems across live crypto markets
Optimize code for performance and low latency across the full research-to-production pipeline
Collaborate directly with quantitative researchers to productionize strategies and ensure research assumptions hold in production
Build and maintain data pipelines for market data ingestion, processing, and storage
Monitor and improve live system reliability, catching and resolving issues before they affect trading outcomes
