Senior Site Reliability Engineer

About the Team

This position is on Slack's technical operations team which is already well established in Dublin. In addition to software engineering, this role requires managing a large and varied infrastructure as it grows.

We build our app using reliable tools that our team knows and trusts, including PHP, MySQL, and Linux. Expertise in these areas is a huge plus, but having familiarity with other common web languages (such as Python or Ruby) and other relational databases are fine substitutes. We’re a collaborative team who genuinely enjoys working together to make Slack a better product. We are looking for engineers that understand that simplicity and reliability are aspects of a system to be carefully calculated with every decision made.
