Job Description

We provide a set of fully managed databases as a platform, used to persist data for all of Cash App. Our platform, running on AWS, automates operating a constantly growing number of databases and database systems like DynamoDB, AWS Aurora, and TiDB. We are responsible for a wide variety of data and access patterns, ranging from mission-critical payment data to high volume user event and sensor data, requiring us to gain deep expertise in a variety of database systems.

Our teams are remote first and globally distributed. You will have high levels of autonomy and curiosity.

As a member of Cash Cloud Database Infrastructure engineering team, you'll collaborate with our stakeholders - including product engineers - to:

  • Design, build, and own infrastructure projects that provide critical support for operating database systems at scale
  • Build the platform that provides self-serve provisioning, scaling, and management of database systems like DynamoDB, AWS Aurora, and TiDB.
  • Build and operate continuous integration and chaos testing for our platform
  • Spread database best-practices across the organization, while mentoring and inspiring fellow engineers

You'll also have the chance to explore and contribute to bleeding edge open source technologies that will form the future of Cash App's cloud storage platform, like TiDB,, and ChaosMesh.


You are a self-motivated, curious engineer who wants to work with stateful distributed systems at scale. Automating chores is second nature. An afternoon spent tracking down an obscure kernel bug is your idea of a good time. You can jump up and down the cloud platform stack at will. The fact that you'll be jumping head first into a massive, distributed cloud platform excites you.

Skills you’ll bring:

  • A curiosity for highly available systems at scale
  • Technical initiative and a desire to make those around you better
  • Experience with incident response, including disaster recovery
  • Proficient in Go or a mainstream scripting language
  • At least one of:
    • Experience operating Data Storage at scale with one or more of the following databases: MySQL, DynamoDB, Amazon RDS, and TiDB
    • Proficient with container orchestration technologies like Docker and Kubernetes

Technologies we use and teach:

MySQL, DynamoDB, TiDB, Amazon RDS, AWS, Kubernetes, Terraform,, Go, and Kotlin. We don’t expect candidates to have experience in all of these technologies.

Cash App spends much of its time using these tools, but we're committed to working on the right tech for the job. As a senior member of the team, we look forward to having your expertise guide us into the future.
