The Site Reliability Engineering (SRE) teams are looking for passionate students with an interest in systems, programming and networking to help in ensuring 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 work together with the product teams to maintain the reliability of existing and new features that are backed by a fleet of microservices, with the infrastructure teams to scale our current data centers and adopt public cloud infrastructure, with the data teams to tackle challenging “big data” issues, and the security teams to keep a close eye on the latest vulnerabilities and constantly protect our product, infrastructure and networks.

The Site Reliability Engineering (SRE) teams are also responsible for designing the systems that allow us to operate on our data centers and evolve the massive Squarespace software engine that serves millions of users worldwide.
