What is a Data Scientist at Susquehanna International Group?
At Susquehanna International Group (SIG), data is not just an asset—it is the lifeblood of the entire firm. As a Data Scientist, you will operate at the intersection of quantitative research, software engineering, and live trading. Unlike traditional technology companies where data science might focus on user growth or product features, at SIG, your work directly impacts financial market-making, algorithmic execution, and risk management. You will build, test, and deploy highly sophisticated predictive models that analyze massive, high-frequency market datasets to identify pricing anomalies and execute trades in fractions of a second.
This role is highly critical because SIG is a leading global proprietary trading firm. The models you build will directly influence how capital is allocated across options, equities, derivatives, and other complex financial instruments. You will collaborate closely with quantitative researchers, traders, and systems engineers to translate mathematical theories into highly optimized, real-world trading strategies.
The environment is fast-paced, intellectually rigorous, and deeply collaborative. Whether you are optimizing existing option-pricing models or exploring alternative datasets to find novel signals, your day-to-day work will involve solving some of the most complex mathematical and computational challenges in the financial industry. For individuals who thrive on immediate feedback, quantitative rigor, and high-impact problem-solving, this role offers an unparalleled opportunity to see your work directly affect the firm's bottom line.
