About Mercury: Mercury is an innovative financial technology company dedicated to developing cutting-edge banking solutions for ambitious businesses. Since our inception as a startup banking platform, we've evolved significantly, now managing tens of billions in deposits. We are excited to announce our next venture: pursuing a de novo bank charter to operate as a fully licensed bank. This is a pivotal moment in our journey. As we transition from fintech to a fully operational bank, we are focused on constructing institutional-grade accounting systems from the ground up. This foundational work begins with this role. Note: Mercury operates as a fintech company and is not an FDIC-insured bank. Banking services are provided through Choice Financial Group and Column N.A., both members of FDIC. The Role: As the Bank Controller, reporting directly to the Corporate Controller, you will take charge of the accounting function for Mercury's banking operations. This is a key leadership position where you will establish the policies, processes, systems, and team necessary for Mercury to function as a fully regulated and insured depository institution. You will be at the crossroads of technical accounting, regulatory compliance, and operational development. This is not a role for those looking to maintain existing functions; it is for those who aspire to architect and innovate while collaborating closely with our Engineering and Product teams. What You'll Do: Bank Accounting Infrastructure Craft and implement the Chart of Accounts, general ledger structure, and subledger architecture for the bank entity, ensuring alignment with call report and regulatory reporting requirements. Establish bank-specific accounting policies related to investment securities (ASC 320/326), loan accounting, interest income accruals, ALLL/ACL methodology, and fee recognition. Develop the bank's financial closing processes and reconciliation frameworks. Regulatory and Call Report Compliance Lead the preparation of FFIEC Call Reports (FFIEC 031/041), FR Y-9C, and other regulatory financial submissions on a quarterly basis. Act as the primary accounting subject matter expert during regulatory examinations (OCC, FDIC, Federal Reserve), addressing examiner queries and managing remediation items. Implement and maintain the bank's accounting policy manual in conformity with GAAP, regulatory guidelines, and safety standards. Collaborate with Treasury on ALM reporting, liquidity coverage ratios, and interest rate risk disclosures. Financial Reporting and Controls Design comprehensive financial reporting frameworks and monitor internal controls to ensure accuracy and compliance. Oversee the preparation and analysis of the bank's financial statements, ensuring transparency and adherence to regulatory standards.

Your expertise in account management and a client-centric approach will be crucial in building long-lasting relationships and contributing to Mercury's mission of empowering businesses with innovative banking solutions.

Arthur C. Clarke famously stated that “any sufficiently advanced technology is indistinguishable from magic.” At Mercury, we strive to provide a magical experience to our customers who depend on us for their banking and financial workflows. However, beneath this enchantment lies a commitment to rigor—internal audit plays a vital role in safeguarding Mercury's integrity, resilience, and the trust of our customers. As Mercury’s inaugural Chief Audit Officer, you will be responsible for establishing and spearheading the independent assurance program that allows us to scale with confidence. You will act as a strategic partner to the Board and Audit Committee, offering an objective, enterprise-wide perspective on our financial, operational, and technical resilience. This position is centered around finding the right equilibrium between high-velocity innovation and the stringent expectations of our partner banks and regulators. By transcending manual checklists and embracing data-driven, continuous monitoring, you will ensure that our growth is firmly anchored in integrity.

Providing Independent Assurance — delivering objective evaluations to the Board and Audit Committee(s) on the effectiveness of our risk management, internal controls, and governance. Auditing the Stack — overseeing technical and operational audits that thoroughly examine our business, automated fund movements, and cloud infrastructure to ensure data integrity and security. Validating the “Magic” — ensuring that our product workflows and financial controls function as intended, identifying potential friction before it affects the customer. Bridging the Regulatory Gap — serving as a key liaison for our partner banks and regulators, instilling confidence in Mercury’s proactive internal oversight. Automating Oversight — designing and implementing continuous monitoring systems that replace manual checklists with real-time, data-driven audit insights. Driving Meaningful Remediation — collaborating with Engineering, Product, and Risk leads to ensure that audit findings lead to substantive improvements rather than temporary fixes.

The electrical grid may not be glamorous, but it is the backbone of our modern world, powering homes, hospitals, factories, and entire cities. At Mercury, we understand the importance of infrastructure that is stable, meticulously regulated, and resilient. When it functions flawlessly, it goes unnoticed; when it falters, everything grinds to a halt. Our Domestic Wires team is integral to Mercury's mission. We are responsible for developing secure, compliant, and dependable domestic wire transfers, enabling businesses to transfer substantial amounts of capital with precision and confidence. The systems we create must strike a balance between speed and safety, scalability and stringent controls, as well as product adaptability and regulatory compliance.
