About Salesforce

We’re Salesforce, the Customer Company, inspiring the future of business with AI+ Data +CRM. Leading with our core values, we help companies across every industry blaze new trails and connect with customers in a whole new way. And, we empower you to be a Trailblazer, too — driving your performance and career growth, charting new paths, and improving the state of the world. If you believe in business as the greatest platform for change and in companies doing well and doing good – you’ve come to the right place.

Come build the infrastructure powering work!

Our Team

Slack's Datastores team builds and operates the database platform powering Slack. We write software to manage thousands of stateful hosts, providing several petabytes of online database capacity. We are building one of the fastest-growing database platforms in the world. Our MySQL databases run in Vitess.

Background

Slack enables people all over the world to communicate and collaborate together. Teams of all scales — from the world’s largest public companies to the smallest of startups — use Slack to get work done, so we take performance and reliability very seriously. A taste of our scale:

• The average user spends over 10 hours connected and 2.5 hours active in Slack every single day

• 1.5 billion+ messages are sent per month, half of those outside the United States

• Every day we see over 10M+ daily active users, over a billion web requests, and 10s of billions of database queries.

For millions of people, Slack is the primary communication tool they use at work all day long. They expect it to be exceptionally reliable and fast, all the time.

Infrastructure at Slack

We operate at tremendous scale with systems that process millions of events per second. Teams in our group maintain and build the lower levels of our stack, including:

• Edge services

• Data Stores and Caches

• Real-time messaging

• Asynchronous background job processing

We know we’ve done our job correctly when none of our users think about us. We don’t typically ship new user-facing features, but rather ensure our systems are incredibly performant, highly available, reliable, and scalable. In other words, Slack just works seamlessly.

Slack's API and web backend is built on PHP/Hack, our backend services are written in Java and Go, and we use Vitess as our storage engine. Our architecture is constantly evolving to handle millions more users. You can read about how we scaled our datastores with Vitess, how we respond to incidents, and much more on our blog.

What you will be doing:

• Operate and enhance our large, highly-available database infrastructure, utilizing technologies such as MySQL and Vitess.

• Develop tools to enable self-service and self-managing capabilities of our database infrastructure so that other teams can operate full-stack while rapidly building new features for our customers.

• Collaborate with engineering teams on their database storage needs, and advise them throughout the development lifecycle.

• Write code to capture database performance, and create tools and dashboards to provide actionable insight into that data.

• Participate in our on-call rotation and collaborate with our operations team to triage and resolve production issues.

• Support FedRAMP and DoD SRG activities.

What you should have:

• Have been working in data storage, core infrastructure, or distributed system-owning teams with incre
