Headquartered in Old Greenwich, Connecticut, WorldQuant is a global quantitative investment management firm and hedge fund. The company develops and deploys systematic trading strategies, predictive algorithmic signals ("alphas"), and data-driven portfolio management models across global equity and financial markets. By combining advanced machine learning, massive financial datasets, and a distributed international network of quantitative researchers, it systematically identifies market inefficiencies to generate consistent, risk-adjusted investment returns.

WorldQuant develops and deploys systematic financial strategies across a broad range of asset classes and global markets. We seek to produce high-quality predictive signals (alphas) through our proprietary research platform to employ financial strategies focused on market inefficiencies. Our teams work collaboratively to drive the production of alphas and financial strategies - the foundation of a balanced, global investment platform.

Excellent ideas come from anyone, anywhere. Employees are encouraged to challenge conventional thinking and possess an attitude of continuous improvement.

Our goal is to hire the best and the brightest. We value intellectual horsepower first and foremost, and people who demonstrate an outstanding talent. There is no roadmap to future success, so we need people who can help us build it.
