Bank Controller

About Mercury:

Mercury is a financial technology company building banking products for ambitious businesses. We've grown from a startup banking* platform to a company that manages tens of billions in deposits — and now we're taking the next step: pursuing a de novo bank charter to become a full-fledged bank.

This is a rare and defining moment. As we transition from fintech to bank, we need to build institutional-grade accounting infrastructure from the ground up. That work starts here.

*Mercury is a fintech company, not an FDIC-insured bank. Banking services provided through Choice Financial Group and Column N.A., Members FDIC.

The role:

Reporting directly to the Corporate Controller, the Bank Controller will own the accounting function for Mercury's banking entity. This is a foundational leadership role — you will build the policies, processes, systems, and team that enable Mercury to operate as a fully regulated insured depository institution.

You'll work at the intersection of technical accounting, regulatory compliance, and operational build-out. This isn't a role for someone who wants to maintain an existing function — it's for someone who wants to architect one and work closely with Engineering and Product.

What you'll do:

Bank accounting infrastructure

• Design and implement the Chart of Accounts, general ledger structure, and subledger architecture for the bank entity in accordance with call report and regulatory reporting requirements
• Establish bank-specific accounting policies covering investment securities (ASC 320/326), loan accounting, interest income accruals, ALLL/ACL methodology, and fee recognition
• Build out the bank's financial close process and reconciliation framework

Regulatory and call report compliance

• Lead preparation of FFIEC Call Reports (FFIEC 031/041), FR Y-9C, and other regulatory financial submissions on a quarterly basis
• Serve as the primary accounting subject matter expert in regulatory examinations (OCC, FDIC, Federal Reserve), responding to examiner requests and managing remediation items
• Implement and maintain the bank's accounting policy manual in compliance with GAAP, regulatory guidance, and safety and soundness standards
• Partner with Treasury on ALM reporting, liquidity coverage ratios, and interest rate risk disclosures
