Slack enables people all over the world to communicate and collaborate together. Teams of all sizes — 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 12M+ 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, and now at home, all day long. They expect it to be exceptionally reliable and fast, all the time.

You will also partner with Cloud Platform and Core Infrastructure engineers, Product Managers and SREs. You will be required to gather requirements, prioritize decisions and ensure timely execution. You focus on creating alignment and giving your team autonomy in order to execute rapidly. You understand the value of career development and can help propel the team forward by facilitating psychologically safe discussions around: project progress, process improvements, mentorship, and general satisfaction.

We operate at a large scale with systems that process millions of events per second. We maintain and build the lowest levels of our asynchronous background job processing system.
