• Contribute to delta hedging, execution, and pricing research that improves trading performance across the firm
• Collaborate with traders and engineers to improve research infrastructure, simulation quality, and data pipelines
• Mentor junior researchers and help raise the quality and rigor of the research process

WHAT WE’RE LOOKING FOR

• 5+ years of experience in quantitative research, systematic trading, market making, or a closely related environment, with a demonstrated track record of developing signals, models, or analytics with measurable trading impact
• Strong statistical intuition and advanced Python proficiency, with hands‑on experience working with large market datasets and designing rigorous backtests and simulations
• Deep understanding of market microstructure, execution, risk, and the practical challenges of moving research into production
• Ability to generate independent hypotheses and collaborate effectively with traders, researchers, and engineers
