Founding Backend Engineer - AI Checkout Agents (NYC)
Jack
Jack is recruiting a Founding Engineer for a seed-stage NYC startup building AI agents that complete real online checkouts. The goal is to let any platform sell anything from any merchant with minimal integration, piloted with major players in payments and infrastructure. You\'d reverse engineer checkout on merchant sites with agents that make purchases, learn, and adapt when sites change or defenses trigger. #J-18808-Ljbffr Jack
