Hire top Site Reliability Engineers to improve system stability 

Here’s what to know before hiring a Site Reliability Engineer 

Historically, development and operations teams often clashed: the former wanted to release new features quickly, while the latter prioritized keeping systems stable and preventing failures. SRE was founded at Google in 2003 to resolve this tension. Its founder, Benjamin Treynor Sloss, famously defined SRE as “what happens when a software engineer is tasked with what used to be called operations.” 

SRE introduced important concepts that provide a measurable way to determine if a system is reliable enough to support new releases. Two of the main concepts are service-level objectives (SLOs) and error budgets. SLOs define key targets for a service’s reliability or performance, while error budgets indicate the maximum amount of failure a technical system can handle before breaching its SLO. 

SRE teams are responsible for continuously monitoring and improving system reliability while enabling development teams to innovate. As Andrew Widdowson, then a Google SRE, once described 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.” 

Long story short, hiring an experienced Site Reliability Engineer allows organizations to build resilient systems that can scale without sacrificing stability. 

So, let’s break down what you need to know to hire a great SRE for your team. 

What is the work of a Site Reliability Engineer like? 

The work of a Site Reliability Engineer focuses on maintaining the reliability, availability, and performance of production systems. 

Much of their role involves designing systems that can handle failures gracefully. They build monitoring and alerting systems (using tools such as Prometheus, Grafana, or Datadog), define SLOs, and create automated processes that reduce operational workload and prevent recurring issues. 

SREs also work extensively with cloud infrastructure and distributed systems. They help manage platforms built on technologies like Kubernetes and cloud services (e.g., AWS, Azure, or Google Cloud), ensuring applications remain stable as traffic and complexity grow. 

From a reliability perspective, SREs monitor system performance, investigate incidents, and conduct postmortems when outages occur. Their goal is not only to fix problems but also to identify root causes and improve the system to prevent similar issues in the future. 

Last but not least, Site Reliability Engineers collaborate closely with software engineers, DevOps teams, and platform engineers to ensure that new features are deployed safely while maintaining system stability and performance. 

How to hire Site Reliability Engineers: a 4-step guide 

1) Define your requirements 

Before hiring a Site Reliability Engineer, take time to consider how your infrastructure is set up and where your applications run. These days, many platforms rely on cloud environments, often combined with container orchestration tools like Kubernetes. In some organizations, however, critical systems may still run on-premises or within hybrid environments. The right SRE for you is the one who is comfortable working within the infrastructure model your company uses. 

Consider your reliability goals. Each product has different expectations for uptime, performance, and user experience. As mentioned earlier, SRE teams typically rely on service-level objectives (SLOs) to measure reliability. They also use service-level agreements (SLAs) to define reliability commitments. A competent SRE who knows how to design, monitor, and maintain these targets will help ensure your systems meet the standards your business requires. 

Another key area to consider is incident management. A strong SRE should know how to design observability systems and implement tools that allow teams to detect (and resolve) issues before they impact users. 

Automation is equally important. Many organizations hire SREs to reduce operational toil by automating repetitive tasks — such as deployments, scaling, or infrastructure provisioning. A candidate with solid experience in automation can improve efficiency while reducing the risk of human error. 

Think about future scalability. If your product is expected to grow, your infrastructure must be able to handle increasing traffic, data volumes, and user demand. Skilled SREs can plan for capacity, design resilient architectures, and implement systems that scale automatically as workloads increase. 

Finally, don’t overlook security and compliance requirements. Depending on your industry, your systems may need to meet strict standards related to data protection and regulatory compliance. An experienced SRE will understand security best practices and know how to operate systems that comply with frameworks such as GDPR (General Data Protection Regulation), HIPAA (Health Insurance Portability and Accountability Act), or SOC 2 (System and Organization Controls 2). 

2) Find skilled site reliability candidates  

As previously mentioned, finding skilled Site Reliability Engineers can be challenging these days. Top talent is in high demand. If you rely solely on job portals, advertisements, and networking, your hiring process may become slow and unpredictable. 

Jobshark is a smarter hiring alternative that provides the speed, quality, and predictability you need. With our all-in-one platform, your hiring process will be more organized than ever. We offer headhunting, tailored technical assessments, in-depth candidate qualification, powerful AI tools, and everything you need to hire the best Site Reliability Engineer for your team. 

3) Assess technical skills 

Site Reliability Engineers do write code, and some companies use technical coding challenges to assess their technical skills. However, assessing SREs often requires a slightly different approach compared to traditional software engineers. An effective way is to combine discussions about real production systems with scenario-based problem-solving tasks. 

Consider giving candidates a practical exercise, such as designing a monitoring strategy for a service or analyzing logs from a failing system. 

You can also ask questions about the systems they have previously worked on. Ask about the scale of those systems, the types of infrastructure they managed, and the reliability challenges they encountered. If they have operated production environments similar to yours, there’s a higher chance they will succeed in the job. 

Explore how candidates approach reliability problems. Ask them to walk through scenarios — such as responding to a production incident, designing monitoring/alerting for a new service, or improving the reliability of a system that is experiencing frequent outages. A strong SRE will apply concepts like observability, incident response, and SLOs in their decision-making process. 

4) Assess soft skills 

Site Reliability Engineers must possess strong communication and collaboration skills, as they work closely with developers and platform teams. When evaluating candidates, pay attention to how clearly they explain complex technical topics or previous reliability challenges. Strong SREs should be able to clearly communicate issues, trade-offs, and solutions to stakeholders. 

Problem-solving is another critical trait. Because SREs deal with unexpected incidents and complex distributed systems, they must approach problems methodically. 

Finally, look for candidates who are adaptable and eager to learn, as the tools and practices used in reliability engineering are constantly evolving.
