Site Reliability Engineer Job Description Example

What does a Site Reliability Engineer do?


SREs are professionals who ensure that computer systems work perfectly without failures or disruptions in most organizations where they operate. This is a hybrid role that crosses over the development-operation divide, meaning it will contribute hands-on to traditional operations team activities. The expertise of SREs is applied in introducing measures that enhance reliability, reduce downtimes, and promote efficiency in the organization’s infrastructure.

Site Reliability Engineer  Job description


The site reliability engineer is a pivotal interface between development and IT ops, performing operational functions that usually fall under operations. This is crucial towards making sure that the computers within an organization are reliable operational and available.

SREs act in advance by using monitoring, automatic approaches, etc., to avoid problems. It involves being “on call” for possible problems and to stop them before they blow up.

They use their tools such as Chef, Terraform, Ansible, Kubernetes, and GitLab CI/CD, to perform their duties of running and overseeing infrastructure. These include activities such as deployment, scaling, and maintenance.

SREs develop robust monitoring facilities focusing on symptom alerting instead of the traditional wait-until-the-outage approach. Consequently, this consists of setting up notifications on different operational problems which the computers could have.
