Job description

Chief Operating Officer — NY Proprietary Trading Firm

Help a NY-based proprietary trading firm build out a hedge fund business on top of their existing operation — without losing the hands-on culture that got them here.

The firm runs multiple trading businesses under one roof across equities, futures, and digital assets. They’re now standing up a hedge fund alongside it. This role owns the operational and structural work that makes that possible.

What you’ll own:

• Register a broker-dealer and lead BD compliance
• Onboard a secondary clearer and strengthen existing prime relationships
• Oversee build-out of real-time risk systems across trading teams
• Unify live balance tracking, accounting, and reconciliation
• Stand up additional international entities and manage local partnerships
• Expand clearing into new regional markets
• Recruit and onboard new PMs
• Support hedge fund capital raising and clearing relationships

You’ll be a fit if you have:

• Direct experience registering a broker-dealer and operating under BD compliance
• Deep familiarity with US equities, CME futures, and clearing relationships
• A strong reputation in the space — useful for fundraising and clearing
• A genuine operator’s instinct: you build, you don’t just oversee

About the culture:

This is a founder-led firm, not a corporate fund. Leadership stays close to the work, and senior hires are expected to operate hands‑on rather than purely through delegation. The team is flat, fast‑moving, and direct.
