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

Lending offers Cash App and Afterpay users low-friction access to credit without prohibitive repayment terms, and the Lending Engineering team is focused on building the complex systems and tooling to support access and availability.The Lending Engineering team focuses on building the products and platforms that help deliver this access and credit to our customers at scale. We're looking for people who are as excited about our mission as they are about the technical challenges we have.

You Will

• Partner closely with credit risk, legal & compliance, product managers and other engineers to take the Lending capability to the next level.

• 5+ years working on complex systems and delivering quality software, with clear expertise developed in one or more technical areas.
