• Own the global payments roadmap and strategy across authorization, routing, retries, tokenization, chargebacks/disputes, and refunds/partial captures, with clear KPIs for conversion, cost, latency, and reliability. • Design and scale a multi-PSP platform, including smart routing, failover, experimentation frameworks, and performance monitoring to continuously improve auth rates and reduce processing costs. • Expand payment methods in the US and internationally, including wallets, local payment methods, EBT SNAP, HSA/FSA, and other emerging options, ensuring compliance with regional and network requirements. • Partner closely with engineering (working with approximately 10–20 engineers) to define PRDs, scope systems, manage delivery timelines, and uphold high standards for availability, security, and PCI compliance. • Collaborate across Platform, Fraud, Order Management, Loyalty, Pricing/Discounting, Shopper (for payouts), and Instacart+ (for subscriptions) to support nuanced flows like post-order changes, substitutions, partial captures, and disbursements. • Manage external relationships with PSPs and card networks—driving performance reviews, negotiating favorable terms, running vendor evaluations, and ensuring SLAs and compliance are consistently met.
