Senior Software/Systems Engineer - Site Reliability at Squarespace
Dublin, IE

The Site Reliability Engineering (SRE) teams are looking for experienced and passionate software engineers and systems engineers who possess backgrounds in systems, programming and networking to help ensure that customers around the world are able to access Squarespace sites, that they load quickly, and that all of the features are working properly.

We build the tools that build Squarespace. From pull request to production dozens of times a day, and just as important, fast push-button rollbacks. We provide the tools to introspect what our code is doing and how it’s doing it. Our footprint is mixed between on-prem and cloud, our job is to choose the right solution to the problem at hand and deliver it efficiently.

Hundreds of engineers, serving millions of sites to millions of users, many millions of times a day. We give our product engineers the confidence to do great things. 

We expect our engineers to lead projects from our offices in Dublin, Portland and New York. While on-call is expected, we value sustainability in our operations and rely on SLOs and error budgets to keep our operational toil in check.
