Company Description

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 47 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.

Job Description

About Health

Cash App has grown rapidly to 70+ million users moving billions of dollars daily. To support this, we are building out Health — a new Platform organization responsible for product experiences aimed at promoting the health of the increasingly complex Cash App ecosystem. Health 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 Health 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).

About Disputes

The Disputes Team is a cross functional product delivery team within Health, established in June 2022. We are responsible for building Cash App’s customer facing transaction disputes experiences. Our mission is to build lasting trust with customers by making disputes more reliable, scalable, and operationally effective while limiting financial losses. In Disputes we build highly available and scalable, Machine Learning driven products that integrate with the broader Cash App ecosystem to help customers solve their problems. Where we can’t solve a customer’s problem through automation, we provide tools and integrations to hand them over to our team of support advocates.

The team currently consists of server engineers, designers, and product management located in Australia, New Zealand and the United States.

The opportunities to have impact are many, and we know we need to expand the team to support global expansion across many time zones and markets.
