Senior Software Engineer - Banking Integration Platform

the opportunity to go on this mission. As part of this role, you will: - Build Mercury's integration with an FFIEC-approved bank core and the connections to payment networks. - Design internal APIs that give product teams simple, consistent interfaces to complex external systems. - Handle the messy realities of enterprise integrations such as retries, failures, format mismatches, and downtime. - Build data pipelines that keep Mercury's systems in sync with our bank core. - Own monitoring, alerting, and recovery for our most critical external connections. - Partner with many other teams at Mercury to define clean boundaries and reliable contracts. - Help shape the technical architecture of Mercury Bank*.
