The position involves designing, developing, and optimizing software for real-time market-making and pricing of U.S. Treasury instruments on a Linux platform. There is a deep emphasis on yield curve analytics and automated spread calculations across benchmark points. The role includes implementing algorithmic hedging strategies driven by real-time curve exposure and DV01-based analytics, along with sophisticated circuit breakers for D2C e-trading platforms to ensure stable operations. The candidate will integrate FIX protocol specifications to facilitate order routing on major Treasury venues (Tradeweb, Bloomberg, and BrokerTec), applying market microstructure expertise to optimize RFQ workflows and internal liquidity routing. Performance profiling is necessary to maintain strict system SLAs, as well as collaboration with risk and compliance teams to conduct regulatory and operational stress tests on order management systems. The candidate will analyze desk requirements to maintain robust venue connectivity and price distribution architecture, while also mentoring junior developers in Treasury electronic trading systems.
