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. Our mission is to provide banking services to all, in particular- those that are underserved. Every one of our customers needs fast and reliable access to their accounts, and the Cash Availability engineering team is responsible for making sure that happens. We care about infrastructure that makes it easy to write software that is secure, efficient, and tested. We examine metrics to find and fix any problems that arise from a massively scaled app, and if those metrics don’t exist we build them. We’re a team of senior engineers with a very wide breadth of experience, and we frequently work in teams to tackle big problems.

As a member of the Cash Availability engineering team, you’ll collaborate with us to:

  • Own infrastructure projects that provide critical support for tremendous processing requirements
  • Dig into the many parts of a large platform using a wide variety of analytical tooling, and if necessary, to add some new ones
  • Use a data-driven approach to make the call on any new infrastructure that might need to be added, whether it’s off-the-shelf or built in-house
  • Knock down pieces of infrastructure, examine the response, improve on it
  • Unit test your stuff
  • Work with bleeding edge cloud and database tech

Qualifications

You have:

  • Boundless curiosity
  • Drive to find flaws in a system with many moving parts and take whatever steps are necessary to fix them
  • Strong desire to perform and grow as an engineer
  • Demonstrated technical initiative and leadership on previous projects
  • Bachelor's Degree or Diploma in Computer Science, or equivalent experience

Technologies we use and teach:

  • Java, Kotlin
  • Go
  • Docker, Kubernetes
  • Jaeger, Prometheus, SignalFx
  • JUnit
  • Hibernate, Vitess, Guice
