Oct 19
It all started with an idea at Square 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, and save to our millions of monthly active users. We want to make the world’s relationship with money more relatable, instantly available, and universally accessible. This is our mission, and it’s why working at Cash App means so much more than a job.
Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward creativity, collaboration and impact. We’ve been a distributed team since day one, and we’ve got offices and remote teammates across the globe. Our offices are great, but 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.Â
