Role Summary

This is a key role within our CASS function, sitting at the intersection of governance, controls and operations. This role would suit someone who wants to move beyond traditional BAU CASS activity and take on broader ownership.

You'll help ensure our CASS framework is not only compliant, but practical, scalable and continuously improving. That means turning operational activity into clear governance evidence, translating regulatory requirements into effective controls, and using data, automation and AI to strengthen how we manage client assets.

Key Responsibilities

• Own and maintain the CASS risk and control framework, ensuring risks, controls and ownership remain accurate and aligned with how the business operates.
• Review control effectiveness and help enhance how risks are assessed, monitored and evidenced.
• Support the migration and modernisation of the CASS control environment, including identifying opportunities to use automation and AI to improve efficiency and accuracy.
• Lead third-party due diligence and oversight across banking and custody relationships, including counterparty and concentration risk.
• Review and approve client money and custody reconciliations, providing effective challenge around quality, timeliness and evidence.
• Investigate reconciliation breaks, control failures and CASS breaches, getting to root cause rather than simply resolving the immediate issue.
• Own remediation tracking and work closely with CASS Operations to put preventative actions in place.
• Produce meaningful management information and trend analysis on breaches, breaks and control performance for governance forums and senior stakeholders.
• Use incident and control data to identify systemic issues and feed improvements back into the CASS framework.
• Support internal and external audits, ensuring the control environment remains audit-ready throughout the year.
• Over time, contribute to CASS impact assessments, regulatory change and broader CASS strategy.
