Job Description

The Site Reliability Engineering (SRE) teams are looking for experienced and passionate software engineers and systems engineers who have backgrounds in systems, programming and networking to help in ensuring that customers around the world can access Squarespace sites, that they load quickly, and that all of the features work. We work together with the product teams to maintain the reliability of our features that are backed by a fleet of microservices, with the infrastructure teams to grow our current data centers and build new ones, with the data teams to solve challenging “big data” issues, and the security teams to keep a close eye on the latest vulnerabilities and 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. We implement software for internal DNS management, IP address allocation, and Linux image and package repositories. We build tools for the provisioning of compute capacity on top of VMware, Kubernetes clusters or public clouds. We work together with Server Engineering teams to scale up our storage, database and search infrastructure, which ingests close to 2 TBs of data per day. Our internal products include source code management tools, clusters of build agents for frontend and server-side code, automated testing infrastructure, Docker image generation tools, and continuous deployment pipelines, all used by 150+ software engineers in the wider organization. We engineer ELK clusters that ingest 5 TB of logs daily, Prometheus deployments that process 14 million data points every minute, distributed tracing services that record 10K spans every second, and alerting frameworks that monitors thousands of servers and hundreds of software services. You will report to the team lead in NYC.

    Write high-quality infrastructure-as-code that automates the provisioning, deployment, scaling, and monitoring of Squarespace’s infrastructure and ensure it's redundant and fast around the globe.
