About the role
Design and scale data systems that support years of market data across multiple asset classes. Own the infrastructure and modeling logic for data ingestion, validation, research, and backtesting, ensuring data remains clean, queryable, and trustworthy. Candidates should have experience designing and scaling large data systems and a background in trading or financial markets. Exposure to quantitative work such as backtesting, pricing, risk, or execution is expected; experience with a major market data or portfolio and risk platform is a plus.
