AI Research Intern

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

This opportunity is only open to students who are currently enrolled in either a Masters or PhD program and offers an 8-month term (with a possibility for extension) on Cash App's Risk AI team starting in Winter of 2024/2025. If you've already graduated (or are set to graduate before May 2025) please apply to one of our full-time roles.

This role is for Block's AI R&D team, which pursues an ambitious agenda of fundamental and applied research. We are a highly creative group that prefers to solve problems from first principles, while moving quickly. At the moment, we are actively working in the areas of Graph Representation Learning, Sequential Modeling, Explainability, and Sequential Decision Making; and we're looking for candidates with experience in these topic areas. We have shown that these technologies have the power to transform the way that Block detects fraudulent behaviour, and are continuing to invest in them.
