Ability to make high-quality decisions rapidly in high-pressure, fast-paced market conditions.
Exceptional verbal communication and interpersonal skills for trading pit negotiations and team collaboration.
Active Series 57 certification.

Quote, facilitate, and trade broker flow in assigned options, equities, and ETF products, providing liquidity and supporting efficient, orderly markets on the BOX floor.

Execute floor-based, voice-assisted, or hybrid options and equity trades, identifying opportunities and representing resting order flow in an open-outcry environment.
Use proprietary pricing software, volatility models, and risk management frameworks to monitor real-time order flow, manage positions, and respond to market volatility or order imbalances.
Partner with electronic trading desks, quantitative research teams, and technologists to optimize workflows, enhance pricing tools, and improve execution performance.
Communicate with floor brokers, counterparties, and internal trading desks to support optimal execution and team coverage.
Comply with BOX exchange rules, SEC regulations, and internal risk and compliance policies.
