All components operate without batch processing, ensuring continuous, low-latency performance across the system.
From a business standpoint, the platform supports core Front Office functions including trading, execution, and order management, with a strong focus on equities and complex financial instruments. Engineers collaborate closely with Front Office–aligned IT teams, contributing to systems that are critical to trading operations while requiring solid domain understanding of capital markets products and workflows.
