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, available and 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.

Are you bored optimizing ads? Do you really want to change the world rather than just say you are? Do you want to be part of the business and have direct influence over business strategies rather than being a “just another scientist”? If so, we have the role for you.
We are hiring for the Head of Network Science and Behavioral Modeling at Cash App. Understanding how network effects enable customer engagement and retention is a strategic priority for Cash. In this position you will have complete ownership and responsibility for building, maintaining and analyzing Cash App’s customer graph for purposes of community finding, business segmentation, quantifying network effect / virality and overcoming customer “cold start”.

Additionally, you will manage other data scientists in the development, implementation and maintenance of a suite of behavioral models to predict customer behavior, specifically churn, winback, product attach and the movement of funds in and out of the cash app ecosystem. The results of these models will be used to drive top-line business decisions, communicate strategies to Wall St. and influence investment decisioning. It is of utmost importance that the modeling specifications are interpretable by a business audience.
