Company Description

Cash App is the fastest growing financial brand in the world. 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 money app with over 15 million active monthly users.

Loved by customers and by pop culture, we’ve held the #1 spot in finance on the App Store for almost two years, and our social media posts see more engagement in a day than most financial brands see in a year.

With major offices in San Francisco, New York, St. Louis, Portland, Kitchener-Waterloo, and Melbourne, Cash App is bringing a better way to send, spend, and save to anyone who has ever sought an alternative to today’s banking system.

Job Description

Cash App is a mobile-first bank that ranks in the top 10 free apps in the app store with a rapidly growing user base and feature set.

  • Knock down pieces of infrastructure and improve on it to demonstrate resilience
  • Work with bleeding edge cloud and database technology

  • Boundless curiosity, autonomy, and a strong sense of accountability
