- Escalate material risk events promptly and proactively.
Requirements
- Degree in Quantitative Finance, Mathematics, Computer Science, Statistics, or a related quantitative field.

- Event-driven options trading (earnings, macro releases) or structured volatility strategies.
Ability to use data tools (Excel, Python, SQL) for research, journaling, and analytics.
