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

Financial reporting and controls

• Review the bank entity's standalone GAAP financial statements, including the balance sheet, income statement, and notes
• Design and operationalize the bank's SOX/SOC controls environment in partnership with internal audit and the holding company controller function
• Lead the bank's relationship with external auditors, coordinating the annual audit and interim reviews for the bank entity
• Establish and maintain robust reconciliation controls covering deposits, loans, investments, intercompany balances, and suspense accounts

Team and systems build-out

• Partner with Finance Systems and Engineering to implement or configure the bank's core accounting system, ensuring it supports regulatory reporting and audit requirements
• Define data flows between the bank's core banking system, the Double Entry Ledger, and Mercury's consolidated reporting infrastructure
• Collaborate cross-functionally with Legal, Compliance, Risk, Treasury, and Product to ensure the bank's accounting architecture supports new product launches and regulatory timelines

What we're looking for:

Required experience

• 10+ years of progressive accounting experience with meaningful time in banking
• Deep familiarity with bank regulatory accounting, including Call Report preparation and GAAP as applied to insured depository institutions
• Strong technical accounting skills across investment securities (ASC 320/326), credit losses (CECL/ASC 326), interest income, and intercompany accounting
• CPA required

Strongly preferred

• Prior exposure to OCC, FDIC, or Federal Reserve examinations in an accounting or controllership capacity
• Hands-on experience building or materially transforming a bank accounting function or experience with a de novo bank charter, bank acquisition, or bank conversion
• Big Four public accounting background with a financial institutions practice

The kind of person who will thrive here

• You are a builder. You get energy from creating infrastructure, not just operating it
• You are comfortable operating in ambiguity. De novo chartering is inherently a process of writing the playbook as you go
• You can translate complex regulatory requirements into practical accounting policies and workflows that a high-performing team can execute
• You communicate fluently with regulators, auditors, engineers, and executives — calibrating your depth and language for each audience
• You have strong opinions on controls and data integrity, and you know how to build consensus to implement them without slowing the business down
