Collateral Business Analyst / SME

G MASS is partnered with a leading Tier 1 Investment Bank, currently undertaking a significant re-platforming of its collateral management infrastructure. The programme involves replacing a legacy vendor solution with a new in-house platform, with a strong focus on controls, exception management and operational workflow redesign.

This role will provide hands-on Business Analysis and subject matter expertise to support the platform change, working closely with Technology, Operations and Compliance stakeholders to translate business requirements into functional design.

Responsibilities

• Lead business requirements gathering for collateral workflows, controls, exception management and platform onboarding across the re-platforming programme
• Conduct gap analysis between the new platform build and current production processes, identifying and resolving operational and control breaks
• Define expected collateral processing logic and validate outputs independently, providing sign-off before Technology implements
• Support design reviews and contribute to the future-state collateral architecture in partnership with Technology, Operations and Compliance
• Develop and execute test scenarios covering key collateral workflows, margin call processing, dispute handling and exception management
• Interpret and apply collateral-related regulatory and operational obligations to the firm's data model and system design
• Produce structured status updates and maintain clear, milestone-driven delivery plans for senior stakeholder reporting
• Support BAU collateral queries and issue resolution as required, on a secondary basis to programme delivery
• Produce documentation covering control ownership, business requirements and implementation readines

Requirements

• 5+ years' experience in collateral management at a Tier 1 Investment Bank, with direct involvement in platform change or system onboarding (e.g. Colleen, Vermeg or equivalent)
• 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
• Strong documentation and stakeholder management skills

Desirable

• Familiarity with collateral platforms such as Colline, Vermeg, Acadiasoft or similar
• Experience with data querying tools (e.g. BigQuery, SQL) for validation and testing purposes
• Understanding of regulatory margin requirements (e.g. UMR, EMIR, Dodd-Frank) as they apply to collateral operations
• Prior experience working in a programme management or structured delivery environment
