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, Lightspeed, NfX and other top-tier investors. Role Overview Business Operations is OpenFX's execution and coordination layer for business-critical initiatives that need several functions to work together: launching new currencies and regions, bringing banking and liquidity partners live, operationalising newly acquired licences, and fixing the cross-team processes that slow us down. The team is deliberately hands-on and horizontal. It creates clarity in ambiguous, high-priority problems, fills execution gaps, and stays with the work until it is delivered, then hands ongoing ownership back to the function that should own it. We are hiring a Business Operations Manager based in the United States to be the single accountable owner for OpenFX's US banking and licence-operationalisation program, and to bring senior generalist capacity to the wider Business Operations portfolio. Today our US work is spread across several people in other time zones. This role consolidates it under one owner who works US hours, sits close to our US partners and regulators, and can carry programs sponsored directly by our executive team through to launch. This is a builder's role in a regulated, multi-entity, multi-country business. You will spend most of your time with banks, custodians, liquidity providers and compliance vendors on one side, and with Legal, Compliance, Finance, Trade Operations, Product and Engineering on the other. You will be judged on whether things go live, not on how much
