It all started with an idea at Block in 2013. Initially built to take the pain out of peer-to-peer payments, Cash App has gone from a simple product with a single purpose to a dynamic ecosystem, developing unique financial products, including Afterpay/Clearpay, to provide a better way to send, spend, invest, borrow and save to our 50+ million monthly active customers. We want to redefine the world’s relationship with money to make it more relatable, instantly available, and universally accessible. Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact. We’ve been a distributed team since day one, and many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy. The Role At Block, we strive to build the best financial products in the world. The Financial Platform Issuing team owns the card issuing platform that serves every Block brand — powering Cash App Card, the largest card program of all, alongside Square Card and the new programs Block launches next. We run the full lifecycle of a card: issuance, fulfillment, and activation; real-time transaction authorization and processing across card networks, digital wallet provisioning, 3-D Secure authentication and the disputes systems. When a customer taps their card at a register, our systems decide the outcome in milliseconds, around the clock, in partnership with card networks and bank partners.
