Senior Manager, Securities Lending Quant

Your opportunity

At Schwab, you’re empowered to make an impact on your career. Here, innovative thought meets creative problem solving, helping us “challenge the status quo” and transform the finance industry together.

As a Senior Manager, Securities Lending Quant, you will serve as a senior desk‑facing quantitative expert within the Treasury Modeling department, focused on securities lending, prime brokerage, margin lending, and equity finance. This role is designed for someone who understands how securities lending desks operate, can speak the language of traders, and can turn market structure, inventory, client demand, collateral, pricing, and P&L dynamics into practical analytics that improve decision‑making.

The ideal candidate brings deep prime brokerage or securities lending expertise, strong quantitative instincts, and a commercial mindset. You should be able to identify trader pain points, challenge existing processes, bring forward innovative quant ideas, and implement solutions that are useful, explainable, and adopted by the business.

This is a high‑impact individual contributor role, not a formal people‑leadership position. You will influence through product expertise, desk judgment, quantitative creativity, and the ability to partner closely with Treasury, Finance, Model Risk Management, product teams, and desk stakeholders. Success in this role requires someone who can bridge desk intuition and analytical rigor while delivering tools and insights that change how the business operates.

If you are a securities lending quant with a strong prime brokerage foundation, a feel for desk economics, and the vision to build next‑generation analytics for trading and balance sheet decisions, we encourage you to apply.
