SREs spend a lot of time removing pain points, configuring internal tools, and setting and testing system benchmarks. They also develop and monitor robust engineering pipelines for everyday product operability. It helps software teams accordingly budget computing resources to maintain a satisfactory service level for all users. Developers decide which parameters are critical in determining the application’s health and set them in monitoring tools. Site reliability engineering (SRE) teams collect critical information that reflects the system performance and visualize it in charts. Therefore, teams plans for the appropriate incident response to minimize the impact of downtime on the business and end users.

Who is a Site Reliability Engineer

SRE serves as the perfect blend of skills to tighten the relationship between IT and developers – leading to shorter feedback loops, better collaboration and more reliable software. SRE teams will help add automation and context to alerts – leading to better real-time collaborative response from on-call responders. Additionally, site reliability engineers can update runbooks, tools and documentation to help prepare on-call teams for future incidents.

Top professionals can polish off their skill sets with strong analytical skills, assessing software and providing ways to quickly patch issues and upgrade products. If SREs can supplement these skills with problem-solving abilities and other beneficial qualities, they can thrive within their work environments. Site reliability engineers should possess knowledge of software development, IT operations, testing procedures and analytical thinking. According to Built In’s salary tool, site reliability engineers (SREs) in the U.S. make an average base salary of $124,604. High performers can ensure they stay in six-figure territory with an additional cash compensation of $12,674, bolstering their total compensation to $137,278.

Site reliability engineers serve as a link between IT operations and software development teams. Depending on the structure of a company, there may be a singular SRE or an entire team dedicated to SRE. System admin tasks generally include maintaining reliability and performance, fixing issues and errors, automating tasks, responding to incidents, and managing on-call responsibilities. For example, a site reliability engineer uses a service to monitor performance metrics and detect anomalous application behavior. If there are issues with the application, the SRE team submits a report to the software engineering team.

Site Reliability Engineer: Skills, Career, Roles and Responsibilities

The service-level agreements (SLAs) are legal documents that state what would happen when one or more SLOs are not met. For example, the SLA states that the technical team will resolve your customer’s issue within 24 hours after a report is received. If your team could not resolve the problem within the specified duration, you might be obligated to refund the customer. Service-level indicators (SLIs) are the actual measurements of the metric an SLO defines. In real-life situations, you might get values that match or differ from the SLO. For example, your application is up and running 99.92% of the time, which is lower than the promised SLO.

Who is a Site Reliability Engineer

According to PayScale, the average site reliability engineering salary in the United States is $117,768 per year. However, salaries can range anywhere from $76,000 to $158,000 per year, depending on experience and location. Monitoring is essential for keeping track of the health of company services and products. As an SRE, you should be familiar with various monitoring tools such as Prometheus, Solarwinds, Pingdom, Zabbix, and Zoho.

Why should I pursue a career as a site reliability engineer?

Site reliability engineers monitor the saturation level and ensure it is below a particular threshold. They help software developers detect latency issues and improve software performance. According to him, people often confuse site reliability engineering as an additional layer in the hierarchy focused solely on monitoring and application/environment uptime. These are usually experienced SREs who’ve worked on teams in one or several of the implementations above. SREs on external facing consulting SRE teams are often called “Customer Reliability Engineers”.

Metrics are quantifiable values that reflect an application’s performance or system health. SRE teams use metrics to determine if the software consumes excessive resources or behaves abnormally. Because an SRE team touches so many different parts of the engineering and IT organization, they can be a great source of knowledge and can be helpful for routing issues to the right people and teams. So, let’s look at common site reliability engineering roles and responsibilities you can expect to see. A site reliability engineer is a tech professional that is development-focused, while a devops is a tech professional that focuses on operations. In addition to switching up your job search, it might prove helpful to look at a career path for your specific job.

On the contrary, it’s a highly creative, stimulating, and technically challenging role. Site reliability engineers must have experience in both IT operations and software development. Outside of education, aspiring SREs professionals should gain at least two to four years of related work experience.

SRE supports teams that are moving their IT operations from a traditional approach to a cloud-native approach. Some of the popular employers as per PayScale include Oracle, Google, Apple, Equifax, VMware, Palo Alto Networks, Microsoft, Cisco, and IBM. SREs will be routinely tasked with managing complex and large-scale infrastructure, systems, and operational problems. Google has even crafted its methodology to quantify this skill, called non-abstract large system design (NALSD) – the ability to build robust and scalable site designs with low operational overheads.

SREs may begin their careers earning $85K, but those who deliver consistent results can pursue salaries up to $255K. Site reliability engineers play a critical role in seamless operations, earning an average base salary of $124,604. The engineers use SRE tools to automate several operations tasks and increase team efficiency. DevOps is a software culture that breaks down the traditional boundary of development and operation teams. Instead, they use software tools to improve collaboration and keep up with the rapid pace of software update releases. For example, an uptime of 99.95% in the SLO means that the allowed downtime is 0.05%.

This can be an implicit or explicit business-level agreement between a company and its customers, noting consequences if the organization does not meet the SLA. They also can include error budgets, which measure the risk an SRE can take for providing services, like maintenance and improvements, without compromising the SLAs. That means facilitating automated, streamlined, and efficient error responses and reducing human error at scale.
