Senior Staff Software Engineer, Trust

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:
Cash App has grown rapidly to 50+ million users moving billions of dollars daily. To support this, we are building out Trust - a new organization responsible for product experiences aimed at promoting the health of the increasingly complex Cash App ecosystem. Trust works to improve Cash App access for our customers, while limiting access for bad or unauthorized users by detecting and preventing improper use across all of our core product areas. The teams under Trust creating these mission critical services and products include Identity, Access, Risk Controls and Support Automation. We appreciate broad perspectives, a willingness to dive deep, and a readiness to work collaboratively across many disciplines (including product, design, operations, legal, data science, ML).
About the teams hiring on Trust:

This is one of the most critical areas for Cash App, and has consistently been a top level business priority for over three years.
