• Improve visibility into firmwide liquidity, intraday funding, and forward cash requirements
• Develop forecasting models for margin, reserve, and collateral demand under base and stress scenarios

• Centralize transparency into collateral pools, availability, and usage across entities and products
• Strengthen controls, documentation, and auditability of collateral and liquidity processes
• Ensure alignment with regulatory requirements

Cross-Functional Execution

• Translate optimization opportunities into actionable initiatives across business lines and support functions
• Partner with Technology and Data teams to enhance automation, reporting, and analytics
• Drive initiatives around netting, pooling, allocation sequencing, and internal liquidity utilization
• Build scalable processes that support growth across products, jurisdictions, and counter parties

Leadership & Communication

• Act as a senior integrator across Treasury, Risk, Finance, and the front office
• Present clear, data-driven recommendations to leadership
• Establish operating cadence and accountability for delivery against optimization targets

Qualifications

• 10–15+ years in treasury, liquidity management, collateral management, securities finance, clearing, or prime services
• Deep understanding of margin, collateral, reserve mechanics, and funding markets
• Strong knowledge of post-trade workflows (settlement, margin, financing, collateral movement)
• Proven ability to drive cross-functional initiatives and influence senior stakeholders
• Experience building analytics-driven decision frameworks
• Comfortable operating in a regulated, control-heavy environment
• Highly analytical, detail-oriented, and execution-focused
