Senior Technical Account Manager, Cash App Pay & Afterpay

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 grown 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 for our 50+ million monthly active customers. We aim to redefine the world's relationship with money to make it more relatable, instantly available, and universally accessible. Today, Cash App employs thousands globally across office and remote locations, fostering a culture of innovation, collaboration, and impact. We’ve been a distributed team since day one, with many roles available remotely in countries where Cash App operates.
