Bank Controller

<h3><strong>About Mercury:</strong></h3> <p>Mercury is a financial technology company building banking products for ambitious businesses. We've grown from a startup <em>banking*</em> 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.</p> <p>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.</p> <p><em>*Mercury is a fintech company, not an FDIC-insured bank.
