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 app, bringing a better way to send, spend, invest, borrow and save to our millions of monthly active users. With a mission to redefine the world's relationship with money by making it more relatable, instantly available and universally accessible, at Cash App you'll have the opportunity to make a real-world impact with your career.

Today, Cash App has thousands of employees around the world with a culture geared toward creativity, collaboration and impact. We’ve been a distributed team since day one, and continue to value working across time zones and continents both remotely and in our Cash App offices.

Our offices are great, but many of our roles can be done remotely from the countries where Block operates. We tailor our experience to champion our employees’ creativity and productivity wherever they are.

The Cash engineering team is responsible for building and maintaining the systems that make it all work.  Every one of our customers needs fast and reliable access to their accounts, and the Cash Availability engineering team is responsible for making sure that happens. We care about infrastructure that makes it easy to write software that is secure, efficient, and tested. This includes the feature flagging interface used by all of Cash Engineering, which we have deep focus on building out safety rails and improving user experience. We examine metrics to find and fix any problems that arise from a massively scaled app, and if those metrics don’t exist we build them. We take an active hand in incident response, both in responding quickly to incidents as well as owning the tooling to improve response. We’re a team of engineers with a very wide breadth of experience, and we frequently work in teams to tackle big problems.
