About the role: As the CASS Oversight Manager, you are responsible for ensuring that client money and custody assets held by Upvest Securities are protected, segregated and accounted for in full compliance with the FCA’s Client Assets Sourcebook (CASS). You will act as the primary day-to-day authority on CASS, bridging the gap between complex regulatory requirements, our operational processes, our client’s needs and our scalable investment API. You will work closely with Product, Engineering, Compliance, Client and Operations teams to ensure our client asset framework remains robust, evidenced and audit-ready, enabling Upvest to scale its financial infrastructure to millions of end-users while maintaining the highest levels of integrity and trust with regulators, clients, and partners. What you’ll do: • Own the CASS oversight framework: Maintain and continuously improve Upvest's CASS risk assessment, controls matrix, policies and procedures across CASS 6, 7, 8, 9 and 10, providing clear guidance to the business on what is and isn't permitted. • Work with our B2B clients, sales and client impact teams to actively shape solutions and provide advice that enables Upvest to support engaging and accessible investing for millions of end users in a CASS compliant way. • Oversee reconciliations and client money calculations: Oversee daily client money calculations and internal and external reconciliations of client money and custody assets, ensuring breaks are investigated promptly, shortfalls are funded and root causes are addressed. • Manage breaches and regulatory reporting: Maintain the CASS breach register, assess materiality, drive remediation and support FCA notifications where required. Own the monthly CMAR submission and act as the primary contact for the annual CASS audit, closing out findings to completion. • Keep the CASS Resolution Pack live: Ensure the resolution pack is complete, current and retrievable within regulatory timeframes, and that it is updated whenever banks, custodians, key vendors or critical staff change. • Embed CASS into how we build: Partner with Product and Engineering teams to assess the client asset impact of new products, features and system changes, and to ensure our ledgers, payment flows and custody integrations do what the rules require by design. • Enhance governance and culture: Produce clear CASS MI for the board and risk committees, deliver CASS training across the organisation, and track FCA developments to assess their impact on Upvest. • Manage external relationships: Support due diligence and periodic reviews of banks, custodians, and maintain acknowledgement letters and mandate registers in the prescribed form.
