- Experience trading directly with inter-dealer brokers (IDBs) matching platforms — voice, or electronic IDB platforms ) — sourcing and providing liquidity across the street
- Solid understanding of trade reporting, settlement mechanics, and the regulatory rules governing inter-dealer trading (FINRA, CAT reporting, best execution)
- Must have three to five years direct experience in market making, and proprietary trading for a broker-dealer in corporate securities
- Comfort working in a fast-moving, high-growth environment where processes are still being built out

Ideal candidates will also have:

- Strong preference for securities lending experience (borrow/loan activity, agent lender relationships, or collateral management)
- Repo/reverse repo experience a bonus
- Margin lending experience a bonus
- Bonus: S24 license
