Software Engineer

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 70+ million users moving billions of dollars daily. To support this, we are building out Trust — a new Platform organization responsible for product experiences aimed at promoting the trust 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).

The Limits Platform team is responsible for applying daily, weekly and monthly limits on customer transactions across the Cash App ecosystem. We do this to manage risk and provide control over our products, and to maintain the trust of our customers. Our systems track transactions across the vast majority of Cash App products, and check them against our limit thresholds. As a server engineer on the Limits Platform team, you will build scalable and performant solutions to protect our customers and allow them to gain access to the global financial system. The contributions you make on this team will be used by millions of people globally.
