Senior Software Engineer - Banking Integration Platform

<p>When the Space Shuttle approached the International Space Station, two vehicles built by different teams, in different countries, with fundamentally different engineering philosophies and systems, had to connect perfectly. The Rendezvous, Proximity Operations, and Docking (RPOD) subsystems were engineered to handle complex mismatches such as different power systems, communication protocols, and technical architectures. Get it wrong, and you have an expensive and potentially catastrophic problem in low Earth orbit.</p> <p>Mercury announced on December 19, 2025 that we submitted an application to the OCC for a national bank charter and applied for FDIC deposit insurance. In other words, Mercury is building a bank. As part of this work, we will be connecting our modern, product-focused engineering systems to enterprise core banking systems and payment networks built in a different era, with different assumptions and different interfaces.
