Security Operations Center (SOC) Engineer

About Us OpenFX is on a mission to move money as freely as data, unrestricted by time zones, banking hours, or legacy systems. We are building the infrastructure that will power the next generation of cross-border payment systems for institutions. The team's execution has been exceptional, and we're scaling at a remarkable pace. Our stellar early team comes with experience in companies like J.P. Morgan, Goldman Sachs, FalconX, Paypal, Affirm, Polygon, Kraken, Nium & others. We're backed by Accel, Faction, NfX, Accomplice, and other top-tier investors. Role Overview OpenFX processes billions of dollars in transaction volume every month across global corridors, connecting banks, liquidity providers, and third-party systems in real time. As transaction volume and geographic footprint scale, so does our threat surface. We need a SOC Engineer who can build and own a high-performance security operations function—one that detects early, responds decisively, reduces systemic risk, and scales ahead of growth. In fintech, a delayed alert is money lost and a missed signal is reputational damage. Security must be operational, measurable, and deeply integrated into how we ship and scale.
