How to hire a site reliability engineer who has held the pager
To hire a site reliability engineer, search beyond the SRE title to production, infrastructure and DevOps engineers who write code, and look for evidence they led incidents and set SLOs. Be specific about on-call load, which SREs weigh first. The Cognitive sources from ~900M public profiles and runs a live AI video interview as the first round.
SRE is what happens when you ask a software engineer to design an operations team. Google, Site Reliability Engineering, Introduction
What are you hiring when you hire a site reliability engineer?
That line from the Google SRE book is still the best hiring test. An SRE writes software to make operations unnecessary. The same chapter describes Google capping SREs' operational work, meaning tickets, on-call and manual tasks, at 50% in aggregate, so the rest of the time goes to engineering.
In practice titles drift. Some companies call their operations team SRE without changing the work. Before you search, decide whether your SRE will write code that removes toil or mostly answer pages, because the 2 attract different people and pay differently.
Where do site reliability engineers work, and what titles do they use?
Search all of these titles, then rank on the signals at the bottom of the list.
- Site reliability engineer, SRE, reliability engineer
- Production engineer, a title some large tech companies use for the same work
- Infrastructure, systems, DevOps and platform engineers who own on-call
- Backend engineers who led incidents and wrote the postmortems
- Signal: authored public postmortems or reliability blog posts
- Signal: spoke at SREcon or contributed to Prometheus or OpenTelemetry
- Signal: names SLOs, error budgets or burn rate alerts in their profile
Search strings written for site reliability engineers
The Boolean string favors people who write code and own reliability outcomes, which filters out ticket-driven operations roles.

PLAIN-ENGLISH BRIEF
Site reliability engineer with 4+ years. Must have led production incidents as incident commander and set SLOs with error budgets. Writes Go or Python to automate operations. Kubernetes and Prometheus in production. US time zones, on-call 1 week in 6.
What does the SRE job market look like in 2026?
No federal code covers SRE. The 3 nearest occupations show how much pay depends on whether the role writes code. Read 5 October 2026.
| Nearest occupation | Median wage | Outlook | Fit for SRE |
|---|---|---|---|
| Software developers (BLS, 15-1252) | $135,980 (May 2025) | 10% growth 2025 to 2035 (with QA and testers) | SREs who spend half their time writing code |
| Computer systems engineers/architects (O*NET, 15-1299.08) | $116,580 (2025, all other computer occupations) | Much faster than average, 2024 to 2034 | Infrastructure and systems engineer titles |
| Network and computer systems administrators (BLS, 15-1244) | $99,130 (May 2025) | -4% 2025 to 2035 | Operations roles renamed SRE |

The detail that decides replies
Put the on-call rotation and a realistic page count in your first message. Experienced SREs ask about it before salary, and vague answers end the conversation.
What should you ask a site reliability engineer in an interview?
Five competencies with a question each. The first one separates people who held the incident commander seat from people who watched the incident channel.
Tell me about the last incident you led from first page to postmortem. What did you do in the first 15 minutes?
Who they paged, what they rolled back or failed over first, and why mitigation came before diagnosis.
How did you know rolling back was the right first move?
How did you set an SLO, and what happened when the error budget ran out?
An SLO built from a user journey rather than whatever Prometheus measured, and a real change in what the team shipped.
How did you cut alert noise for the on-call engineer?
Replaced CPU threshold alerts with burn rate alerts, and knows which dashboards on-call engineers actually opened.
Describe a failure that spread from one service to another.
A retry storm that saturated a connection pool and took down an unrelated service, plus the guardrail added after.
What would have caught it earlier?
What toil did you automate, and how did you decide it was worth it?
Measured the hours first, such as weekly certificate rotation, then explained why an operator beat another cron script.
A hiring process for a site reliability engineer, step by step
Six stages. Stage 5 replaces the usual whiteboard with an incident, because that is the job.
- Define the split and the rotation Write how the time divides between engineering and operations, and the on-call schedule, before anything else. About 60% engineering, 1 week on-call in 6, roughly 3 pages a week.
- Source across reliability titles Search SRE, production, infrastructure and DevOps titles together, and rank people who show incident and SLO ownership first.
- Reach out with the rotation Name the systems, the on-call load and the reliability problem you most need solved. Honesty about pages earns replies.
- First round on incidents and SLOs A 20 minute conversation on incident response, SLOs, observability and toil, scored on one rubric for every candidate.
- Run a simulated incident Give a real past outage with graphs and logs, and watch how they triage, communicate and choose a mitigation.
- Code review, team round, offer Review automation they wrote, meet the people sharing the rotation, and make an offer quickly. Good SREs leave slow processes.
The incident question, asked live before your team joins
The AI follows up on what the candidate says, such as what exactly they rolled back.
In The Cognitive, the rubric is fixed per role and the questions adapt. A candidate who says they mitigated quickly gets asked what they rolled back and how they knew. The AI probes up to 5 resume claims and marks each verified, refuted or unclear.
How does The Cognitive help you hire a site reliability engineer?
I run The Cognitive. It covers stages 2 to 4. Type the brief above, search ~900M public profiles, and check each card's "Open to work" badge and tenure per role before revealing verified emails and phone numbers. Then invite the people you like to the AI interview for site reliability engineers.
Each report scores every criterion from 1 to 5, adds overall written feedback, and includes the transcript and recording, so your on-call lead can replay the incident answer. If candidates sit in your ATS, 60+ integrations write a note back, and stages never move. AI Sourcing and AI Interview each start at $99/month.

Frequently asked questions
How much does it cost to hire a site reliability engineer?
There is no federal SRE wage figure. Software developers had a median of $135,980 in May 2025 and systems administrators $99,130, and SRE pay tracks the software side when the role writes code. Tooling is separate: AI Sourcing and AI Interview each start at $99/month.
Where can I find SRE engineers?
Under SRE, production engineer, infrastructure and DevOps titles at companies running large online services. Public trails help: postmortem write-ups, SREcon talks, and contributions to Prometheus or OpenTelemetry.
What is the difference between an SRE and a DevOps engineer?
An SRE owns reliability targets such as SLOs and error budgets and writes software to cut operational work. DevOps engineers often focus on delivery pipelines and infrastructure. Many people have done both, so assess the work, not the title.
How long does it take to hire a site reliability engineer?
No public source gives a reliable time to fill for SREs. The waits you control are sourcing, scheduling the first round and booking a simulated incident with your team. A self-booked first round removes the second.
What should an SRE job description include?
The split between engineering and operations work, the on-call rotation, realistic page volume, the systems they will own and the reliability targets. Our site reliability engineer job description template covers each.
Can an AI interview assess incident response?
It can assess how a candidate reasons about incidents they led: first moves, communication and the postmortem, with follow-ups on vague answers. A hands-on simulated incident with your team should still come later.
Should my first SRE be senior?
Yes, in most cases. The first SRE sets on-call practice, alerting and SLOs for everyone else, and needs the authority to push back on releases. A junior engineer in that seat usually ends up answering pages without changing the system.
