Establish and maintain effective governance and validation processes, perform regular reviews and audits, and work with internal and external stakeholders to resolve data quality or reporting issues.
Reporting Controls, Reconciliation, and Review: Own end-to-end reconciliation and exception management for all core transaction and position reporting. Routinely perform data integrity reviews and support internal or external audit activity for ongoing compliance.
Automation, Technology Liaison & MI Production: Collaborate effectively with technology teams to identify requirements and support the delivery of automated solutions for regulatory reporting and reconciliation. Drive the production of high-quality management information (MI), supporting senior management, compliance, and regulatory needs.
Broader Reporting Scope & Change: Support, as required, reporting under additional regimes (such as commodity position limits, Dodd-Frank, SEC 13F/13H, etc.), participate in regulatory change projects, and keep abreast of and prepare for evolving regulatory requirements and new reporting obligations.
Stakeholder Engagement: Act as SME for key reporting regimes; provide advice and training across the business; support senior leadership, audit, and regulatory inquiries as required.
