• Proven Business Analysis skills — requirements writing, acceptance criteria, structured documentation and delivery tracking
• Deep knowledge of collateral workflows including margin call processing, dispute management, exception handling and control frameworks
• Hands‑on experience working alongside Engineering / Technology teams on collateral platform implementations
• Strong understanding of data lineage, reconciliations and operational control design
• Ability to translate complex business requirements into clear functional specifications for IT delivery
• Experience managing and communicating milestone‑driven delivery plans to senior stakeholders

• Familiarity with collateral platforms such as Colleen, Vermeg, Acadiasoft or similar
