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).
