Senior Software Engineer - Cloud Database, Cash App

It all started with an idea at Square in 2013. 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, bringing a better way to send, spend, invest, and save to our millions of monthly active users. We want to make the world’s relationship with money more relatable, instantly available, and universally accessible. This is our mission, and it’s why working at Cash App means so much more than a job.

Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward creativity, collaboration and impact. We’ve been a distributed team since day one, and we’ve got offices and remote teammates across the globe. Our offices are great, but many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy.

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 the Cloud Database 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, ElastiCache, ElasticSearch, 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, Temporal.io, 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.
