Senior Engineering Manager – Domestic Wires & Real-time Payments

Wire transfers trace their roots back to the telegraph, early systems built to move information and eventually money across long distances with speed and certainty. That legacy still defines how wires work today: they are fast, final, and effectively immutable. Once a transaction is sent, it cannot be undone. This makes wires some of the most exacting systems in modern finance. They power critical moments for businesses, including payroll, large vendor payments, and capital movement, where precision, reliability, and trust are essential. When they work, they’re invisible. When they don’t, the consequences are immediate. At Mercury, wires and real-time payments sit at the core of how businesses move money. The Domestic Wires & RTP team builds the systems behind secure, compliant, and reliable money movement, enabling customers to move significant amounts of capital with confidence. These systems must balance speed with safety, scale with strict controls, and product flexibility with regulatory requirements. As instant payments become the expectation rather than the exception, the importance and complexity of this work continues to grow. And as Mercury pursues a bank charter, this team is at the leading edge of building the infrastructure and controls required to operate bank-grade payments systems. We’re looking for a seasoned engineering leader to guide the Domestic Wires & RTP team through its next stage of growth.
