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.

Remote Work

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. 

This opportunity is only open to students who are currently enrolled in a PhD (or Masters) program and offers a 4-month term (with a possibility for extension) on Cash App's Machine Learning Engineering team starting in Fall of 2022. If you've already graduated (or are set to graduate before the end of 2022) please apply to one of our full-time roles.

Machine Learning is an integral part of how we design products, operate, and pursue Cash App’s mission to serve the unbanked as well as disrupt traditional financial institutions. Our massive scale and deep trove of data create an endless number of opportunities to use artificial intelligence to better understand our customers and offer new products and experiences that can improve their lives. We are a highly creative group that prefers to solve problems from first principles; we move quickly, make incremental changes, and deploy to production every day. 

This internship is part of our Cash App's Recommendations & Incentives Machine Learning team (RIML). This team provides an ML-powered recommendation services platform that works for the entire gamut of our Product Abstractions and enables Cash to make creative and personalized customer experiences. Furthermore, our ML models used for incentives programs consistently provide value to the business and our customers by attracting and engaging more customers which directly contributes to the massive success of Cash.
