Sr. Database Reliability Engineer

About the Team

Slack's Database Reliability Engineering team builds and operates the platform services that store data at Slack. We write software to manage thousands of stateful hosts, providing many petabytes of online database capacity. We are also in the midst of transitioning Slack’s core MySQL infrastructure to use Vitess’ flexible sharding and management capabilities.  Review our recent presentation slides: Migrating to Vitess at (Slack) Scale.

Slack has a positive, diverse, and supportive culture—we look for people who are curious, inventive, and work to be a little better every single day. In our work together we aim to be smart, humble, hardworking and, above all, collaborative. If this sounds like a good fit for you, why not say hello?
