You will help build and operate the systems that ingest and integrate global card-network settlement and report files (Visa, Mastercard, and equivalents), along with data from acquirers, processors, and banks, and reconcile them against internal payment data to power settlement, dispute, cost, tax, and regulatory reporting. Contribute to our large-scale tax and regulatory reporting systems, including US IRS information returns (the 1099 family, issued at the scale of tens of millions of forms annually to merchants and customers) and international regimes such as EU-wide CESOP and country-specific reporting for Australia, Ireland, and Spain.
