- Site reliability engineers apply software engineering methods to production systems, writing the code and automation that would otherwise be done by hand as manual operations work.
- They sit between development and operations teams, usually take a turn on the on-call roster when something breaks, and set the reliability targets other engineering teams design against.
- The role is often confused with DevOps engineering: a DevOps engineer typically builds the pipelines that get code into production, while a site reliability engineer usually owns what happens to it once it is live.
How much do site reliability engineers earn?
The median full-time salary for a site reliability engineer is $122,200 per annum, before tax, up $25,300 since 2018.
Pay moves most with the sector and the size of the employer: banks, telecommunications companies and large cloud providers typically pay above the median, while smaller software businesses often pay less. Whether on-call is paid as a separate roster allowance or built into the base salary makes a real difference to what lands in your account, so it is worth asking how the roster is compensated. Certifications help at the margins, but experience running production systems is what employers pay for.
What does a site reliability engineer do day to day?
The list below is what fills most weeks; the exact mix shifts with seniority and whatever stage the current work is at.
- Writing automation and scripts so a manual fix never has to be done by hand twice
- Watching dashboards and alerts and deciding whether a blip needs action or can wait
- Tracing the root cause of an outage through logs and metrics while customers are affected
- Running a blameless post-incident review and turning what went wrong into a concrete safeguard
- Negotiating realistic reliability targets with engineering teams instead of chasing zero downtime

Is the job growing?
About 8,900 people work as site reliability engineers in Australia, and employment is projected to grow 18% over the decade to 2035. That's healthy, above-average growth, and the role should stay in solid demand.
How do you become a site reliability engineer?
Here's the path most site reliability engineers take, step by step.
- 1Build a technical foundation
A bachelor degree in computer science, software engineering or IT is the most common way in, and 38% of the people currently in the role hold one. A diploma or advanced diploma in IT can also lead here, usually after a few years of hands-on systems, support or development work.
- 2Start in a role that touches production
Most site reliability engineers arrive from cloud engineering, network engineering or software development rather than starting with the title. Any job where you deploy, monitor or troubleshoot live systems gives you the experience employers ask about.
- 3Learn the toolchain on real systems
Employers expect familiarity with a cloud platform, containers and orchestration such as Kubernetes, infrastructure as code with Terraform, and monitoring tools such as Prometheus. A home lab or a project at work teaches this faster than study alone, and vendor certifications like the AWS Certified DevOps Engineer or the Certified Kubernetes Administrator are recognised markers, though not a requirement.
- 4Volunteer for on-call and incident work
The quickest way into the title is taking shared on-call and incident duties at your current employer, then automating whatever keeps breaking. A record of reducing incidents is what a hiring panel looks for.

What's it like being a site reliability engineer?
The job runs on two rhythms. Most weeks go to improvement work: automating a manual step, tuning noisy alerts, or working out why a service slows down under load. That work gets interrupted when something breaks, and a place on the on-call roster means the interruption can arrive at night or on a weekend. People who enjoy it tend to like knowing how a whole system fits together and prefer fixing the cause of a problem to working around it.
What people like
- Fixing the cause rather than the symptom. An incident is only closed properly once the underlying fault is gone, so the role suits people who want the real problem solved.
- You learn how the whole system fits together. Reliability work touches the network, the database, the deployment pipeline and the application code, which builds a broad picture of the stack quickly.
- Automation removes boring work for good. A script that deletes a weekly manual task is a permanent gain, and reducing toil is treated as part of the job rather than a side project.
- Blame stays off the person. Well-run teams review incidents to find the systemic cause, which suits people who would rather improve a process than defend themselves.
What people find hard
- On-call follows you home. Most teams run a roster, so nights, weekends and public holidays can be interrupted, even if the pager stays quiet on many shifts.
- Planned work gets interrupted. A live outage takes priority over the automation project you had scheduled that day, and the project slips.
- Good reliability is invisible. Nothing happens when a service stays up, so the work is noticed mainly when something fails and it can be hard to win time for it against new features.
- You are often the brake. Pushing back on a release that is not ready can put you at odds with the team that built it.

Will AI replace site reliability engineers?
Moderate exposure. Not replaced, but changed. AI is taking on some tasks and the rest of the job shifts around them.
This is a moderately exposed role. A fair share of the repetitive work, writing routine scripts, drafting dashboards and spotting anomalies in metrics, is already automated or assisted by AI. What keeps the exposure in check is that the decisions that matter, what to automate, how to respond to a live incident and how much reliability a service needs, depend on context the tools do not have.
How a typical week splits
- Monitoring, dashboards and alert tuning30% of the week
Observability tools already cluster related alerts and flag anomalies, so much of the pattern-spotting that used to fill a shift is handled for you.
- Writing automation and infrastructure code25% of the week
Coding assistants draft Terraform, scripts and Kubernetes manifests quickly, but someone still reviews them and decides what is safe to run against production.
- Capacity planning and performance analysis20% of the week
Forecasting tools model traffic growth from historical metrics, but judgement about headroom, cost and acceptable risk stays with the engineer.
- Incident response and on-call triage25% of the week
AI can summarise what changed in the minutes before an alert fired, though working out the cause and choosing a fix during an outage remains human work.
How we work this out
We break each job into its main tasks, estimate the share of a typical week each one takes, and judge how far current AI and automation tools reach into it. The score out of 10 starts from the job's overall rating (low is 1 to 3, moderate 4 to 6, high 7 to 10) and the task split places it within that range.

Common questions about becoming a site reliability engineer
Straight answers to the questions people ask most.
How much does a site reliability engineer earn?
Median full-time pay is $122,200 per year before tax. Pay varies with the sector and size of the employer, and with whether on-call is paid as an allowance on top of base salary.
How do you become a site reliability engineer?
Most people enter through a related engineering role and move into reliability work once they have production experience. A degree or diploma in computer science or IT helps, but familiarity with Linux, a cloud platform, containers and monitoring tools is what hiring managers test for.
Are site reliability engineers in demand in Australia?
Site reliability engineers are currently in shortage nationally, and employment is projected to grow 18% over the decade to 2035 over the decade to 2035. Employers in banking, telecommunications and cloud services hold most of the roles, and production experience counts for more than the job title on your resume.
Will AI replace site reliability engineers?
Not in the near term, though parts of the work are exposed. Observability platforms already detect anomalies and draft dashboards, and coding assistants write routine scripts and Terraform configuration, which removes some repetitive effort. Deciding what to automate, running an incident when an alert is genuine, and negotiating reliability targets with other teams still sit with the engineer.
What is the difference between a site reliability engineer and a DevOps engineer?
A DevOps engineer usually builds the pipelines and tooling that move code into production, while a site reliability engineer owns how that code behaves once it is live, including reliability targets and incident response. The two roles overlap heavily, and some employers use the titles interchangeably.
What can a site reliability engineer move into?
Cloud engineering shares 64% of the skills and typically pays $10,400 less, since both roles centre on infrastructure automation and monitoring. Software engineering brings $9,700 more but needs more study in application design, while data engineering draws on 62% of the same skills. These sit inside engineering, so the usual progression is deeper technical specialisation or leading a reliability team.
