Sr. Software Engineer, Site Reliability Engineering

About the Team

The Site Reliability Engineering (SRE) team manages and scales core components of Slack’s infrastructure and product. We continuously seek to improve the visibility, speed, and safety of Slack’s distributed application architecture.

We are a growing and evolving team, welcoming new perspectives and strategies to address evolving challenges to reliability.  We collaborate with many product and infrastructure engineering teams at Slack to continuously improve shared technology and processes, improving the baseline of reliability. 

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?
