Site Reliability Engineers are Software Engineers who specialize in site reliability engineering (SRE). SRE is used to manage and develop software systems that are reliable and scalable. SRE began at Google in 2003 when the company needed Software Engineers to make their large-scale sites more reliable and efficient. The result was so successful that other big tech companies soon started following the same practices.

Site Reliability Engineers are now used to develop more efficient software systems for businesses in almost every industry. They may develop better systems for communication, manufacturing, healthcare, and many other areas of business.

What they do

Site Reliability Engineers are responsible for developing and managing software systems, typically focusing on systems used for maintaining local or public websites. They also bridge the gap between software development and business operations.

Develop Efficient, Scalable Software Systems

The main duty of a Site Reliability Engineer is to develop efficient, scalable software systems. They work on projects to help ensure that IT products are easy to use and highly adaptable. These systems should require minimal input and operational procedures.

The software systems that Site Reliability Engineers typically work on include websites. This may include local sites that are part of an organization’s intranet and intended only for internal use. They may also work on public-facing websites or online services. Along with sites, Site Reliability Engineers help develop more efficient cloud computing solutions, IT infrastructure, or software as a service (SaaS) solutions).

Automate Tasks to Streamline Software Systems

Site Reliability Engineers often develop automated processes to increase the efficiency of software systems. They add automated scripts to existing software to reduce the need for human involvement. The most efficient systems do not require any manual input.

Perform On-Call Monitoring of Software Systems

Site Reliability Engineers may deal with on-call monitoring and business operations. They address any technical issues that arise and walk end-users through troubleshooting scenarios. These tasks are also completed by other IT professionals. However, Site Reliability Engineers engage in on-call duties to learn more about the performance of the software that they work on.

Some organizations limit the amount of time devoted to operations. Site Reliability Engineers spending a significant amount of time on operations and monitoring indicates a lack of efficiency and scalability. When the software solutions perform as expected, Site Reliability Engineers should not need to focus on operations, as their main duties include improving and designing more efficient systems.

Collaborate with Developers to Design New Solutions

When a project requires the development of new software, Site Reliability Engineers typically collaborate with other IT professionals, including Software Developers and Software Engineers. They may also work with the DevOps team, as SRE is often used as part of a DevOps model. Depending on the size of the company, Site Reliability Engineers may work with Release Engineers after the software is developed. They work to ensure that the software meets expectations.

Create Software to Support Other Departments

Site Reliability Engineers may work on the development of software systems intended to support other departments and teams within the organization, such as the IT operations team or the IT support teams. This includes the creation of automated scripts and monitoring software.

Complete Post-Incident Reviews

After a project, Site Reliability Engineers need to complete a post-incident review. This allows them to analyze whether their solutions were effective at reaching specific business objectives. They may also compile reviews from other members of the IT department. The post-incident reviews provide Site Reliability Engineers with the information needed to optimize the reliability and efficiency of the software.
