Google’s mastermind behind SRE, Ben Treynor, still hasn’t published a single-sentence definition but describes site reliability as “what happens when a software engineer is tasked with what used to be called operations. 

Site Reliability Engineer is the most promising jobs of 2019 Unveiled by LinkedIn based on LinkedIn data.

What is a Site Reliability Engineer?

What exactly is SRE?

Lets take a scenario from development environment.

There are typically two teams called developers team and operations teams. Developers design new features and try to add more value to products. On the other hand, the Operations team has to make sure that the newly added features don’t blow up things that are working fine without them. Operations teams try to make a few releases as possible while Developers try to continuously deliver as many features as they can. This causes a lot of debate over what can be launched and when.

The goal of SRE is to resolve the above-discussed issue. SREs are tasked with a dual purpose of developing new features while also ensuring that production systems ran smoothly. Many times they are compared to DevOps but here is a general difference, DevOps are more like a collaboration between Developers and Operations and focus more on deployments while SRE is more focussed on monitoring and operations.

What is an Average Salary?

Salary:

The average salary for a Site Reliability Engineer is $134,762 per year in the United States. Salary estimates are based on 1,357 salaries submitted anonymously to Indeed by Site Reliability Engineer employees, users, and collected from past and present job advertisements on Indeed in the past 36 months.

According to Glassdoor the national average salary for a Site Reliability Engineer is ₹14 lakhs/yr in India.

Job Responsibilities:

As Google’s own SRE Andrew Widdowson describes it, “Our work is like being a part of the world’s most intense pit crew. We change the tires of a race car as it’s going 100mph.”

SRE teams are staffed with a highly apt developer/sys-admin hybrids who are expert in finding problems as well as fixing them. They can work easily collaborate with development teams and ensure that production systems are running smoothly while developing new features.

In fact, one of the core principles mandates that SRE’s can only spend 50% of their time on operations work. As much of their time as possible should be spent writing code and building systems to improve performance and operational efficiency.

Some of the responsibilities of a Site Reliability Engineer are:

Work alongside the Developer team to ensure new features are being developed smoothly and being deployed without a hitch.

Help prevent and investigate production issues.

Partner with Product Engineering teams to improve operational best practices.

Incident Management – leading the charge and coordinating an investigation for production issues, post-issue follow-up, and ensuring learned improvements are implemented.
