About Citadel Global Quantitative Strategies (GQS)
GQS is the systematic investment business within Citadel. Founded in 2012, it is the youngest of Citadel's core investment strategies. Our team of researchers, engineers and traders develop quantitative models and scalable systems to autonomously identify and capture investment opportunities across global markets.
C++ at GQS
At GQS, C++ is central to our end-to-end systematic investing platform. We use modern C++ to build low-latency, performance-sensitive applications that serve proprietary research data, power the core analytics libraries used for quantitative research and real-time forecasting and execute GQS systematic trading. Across the entire investment workflow, C++ is critical to GQS production systems that directly translate to business results.
Key Responsibilities
C++ Quantitative Research Engineers at GQS work on a wide variety of challenges in collaboration with Quant Researchers. Examples include:
  • Real-Time Data Processing: Develop robust low-latency applications that ingest and normalize terabytes of data spanning a vast set of asset classes from hundreds of exchanges and vendors worldwide each day.
  • High-Frequency Trading Systems: Architect and evolve high-performance trading execution systems with uncompromising standards for latency, reliability, and correctness.
  • Low-Latency ML Inference: Build research tools on top of cutting edge statistical and machine-learning libraries to enable our researchers to ideate and productionize market forecasts with velocity and academic rigor.
