Product Manager - Prime Product & Margin in London

Citi's Markets division is one of the world's leading providers of financial products and services across fixed income, equities, currencies, commodities, and prime finance. Within Markets, Prime Finance serves as a critical infrastructure for hedge funds and institutional clients, delivering financing, securities lending, margin, and portfolio solutions across a broad range of asset classes. The business operates at the intersection of client service, risk management, and technology, and plays a central role in Citi's global Markets franchise.

This is a Director-level opportunity within Citi's Prime Finance business, focused on Cross Product Margin (CPM) — a strategically important and technically complex area that sits at the heart of how the firm manages margin efficiency across asset classes for its institutional client base. The successful candidate will lead the product management function for CPM, driving the design, development, and delivery of cross-asset margin frameworks and the technology platforms that underpin them. This is a high-visibility role with direct exposure to senior business, technology, and risk stakeholders, and offers the opportunity to shape a capability that is increasingly central to competitive differentiation in prime brokerage.

• Lead the end-to-end product lifecycle for Cross Product Margin capabilities within Prime Finance, translating complex margin methodologies — including scenario-based, VaR, and Expected Shortfall frameworks — into scalable, well-defined product requirements for technology delivery.
• Define and drive the strategic roadmap for CPM infrastructure, working across execution, clearing, and margin technology to converge platforms into a cohesive, globally consistent architecture.
• Act as the primary subject matter expert on cross-asset margin frameworks, including portfolio-level offsets, concentration add-ons, liquidity haircuts, and regulatory overlays across equities, fixed income, FX, futures, and cleared derivatives.
• Partner with Trading, Risk, Operations, Legal, and Compliance to ensure margin product design meets both commercial objectives and regulatory requirements, including FINRA Rule 4210, Regulation T, ISDA/CSA mechanics, and evolving central clearing mandates.
• Engage directly with institutional clients and internal stakeholders to identify margin optimisation opportunities, articulate product capabilities, and support the development of client-facing margin tools and reporting.
• Drive governance and prioritisation across a portfolio of cross-functional technology programmes, ensuring delivery against agreed timelines and commercial outcomes in a complex, multi-stakeholder environment.

• Significant experience in a product management, business analysis, or senior operational role within Prime Brokerage, Prime Finance, or a closely related area at a global financial institution or broker-dealer — typically 10 or more years.
• Deep technical knowledge of margin frameworks across multiple asset classes, including familiarity with SPAN, TIMS, VaR, and Expected Shortfall methodologies, as well as cross-margining structures and portfolio margin concepts.
• Strong understanding of the regulatory landscape relevant to prime finance and margin, including Regulation T, FINRA Rule 4210, SEC 15c3-1/15c3-3, and ISDA/CSA collateral mechanics; awareness of central clearing developments is highly advantageous.
• Demonstrated ability to translate complex, technical concepts into clear product requirements and to influence and align senior stakeholders across business, technology, risk, and compliance functions.
• Cross-asset product knowledge spanning equities (cash and synthetic), fixed income, FX, futures, and cleared swaps, with an understanding of how margin interacts with financing, securities lending, and client portfolio structures.
• Strong academic background, typically a degree in a quantitative, financial, or technical discipline; a postgraduate qualification or CFA charterholder status would be advantageous but is not essential.
