Quantitative investment manager building trading and portfolio analytics systems

Financial Services New York, NY 1,001–5,000 employees Privately Held

Two Sigma is a quantitative investment firm running Python, C++, Java, and a heavy ML stack (PyTorch, TensorFlow, scikit-learn, JAX) across ~1,700 employees. Active migration to cloud-native infrastructure (AWS, Azure, GCP, Kubernetes) and adoption of FPGAs suggest a shift toward lower-latency execution and real-time feature computation. Engineering-heavy hiring (17 roles) combined with active research teams (9 roles) and projects around low-latency frameworks and model productionalization indicate scaling bottlenecks in trading systems and research-to-production workflows.
