Quantitative Researcher

Quantitative Researchers at Jane Street help build models, strategies, and systems that price and trade financial instruments. You'll work alongside experienced researchers learning experiment design, dataset generation, time series analysis, feature engineering, and model building for financial datasets. Our researchers, engineers, and traders collaborate closely to train models, architect systems, and run trading strategies using petabytes of data and sophisticated computing infrastructure. You'll work across diverse tasks including market data analysis, hyperparameter tuning, debugging distributed training, and studying model performance in production. We apply a wide range of statistical and ML techniques—from linear models to deep learning—tailored to specific problems rather than one-size-fits-all solutions.
