Company Description

Cash App is the fastest growing financial brand in the world. 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 app with over 36 million monthly active users. We are bringing a better way to send, spend, invest, and save to anyone who has ever sought an alternative to the traditional banking system. 

Loved by customers and pop culture, we’ve consistently held the top spot for finance in the App Store for many years, seeing more engagement with millions of followers across social media in a day than most brands see in a year. We are building an ecosystem to redefine the world’s relationship with money by making it universally accessible.

We want to hire the best talent regardless of location. Our employment model is distributed, offering the opportunity to collaborate with teams across the world in San Francisco, New York, St. Louis, Portland, Toronto, Kitchener-Waterloo, Sydney, and Melbourne.

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. Our mission is to redefine the world's relationship with money by making it more relatable, instantly available, and universally accessible.

Cash App is built as a service mesh, communicating via synchronous APIs as well as asynchronous events, built on AWS and Kubernetes. Tax is a recently acquired product running on Google Cloud Platform and Kubernetes that needs to be integrated into the Cash App ecosystem.  The Tax Platform team is responsible for the mission-critical fabric that these services run on, and provides DevOps, service discovery, routing, self-healing, observability, and developer efficiency features that product teams use to operate their systems on Cash App’s platform.

  • Knock down pieces of infrastructure and improve on it to demonstrate resilience

  • Work with bleeding edge cloud technology


You have:

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

  • Strong desire to perform and grow as an engineer, and mentor other engineers
