SRE Recruiters Who Ask How Many Nines You Actually Need
Reliability searches go wrong at the brief, not at the shortlist. We size the availability target, the on-call rotation and the comp band on the first call, because those three things decide which of four very different engineers you’re really hiring.
KORE1’s SRE recruiters place site reliability engineers who own SLOs, error budgets and production on-call, screening on incident ownership rather than tool lists. Average time to fill across our technology desks is 17 days, and 92% of the people we place are still in seat a year later.

A VP of engineering called us last year and opened with four words. He wanted a Google SRE. Those words exactly. His platform was a Rails monolith and two dozen services on EKS, his contractual commitment to his largest customer was 99.9%, and he had one person carrying the pager alone for eleven months.
99.9% is 43 minutes a month. Not 43 seconds. Nobody had done that arithmetic out loud. So the role got written for the hardest version of the job, priced at the hardest version of the job, and sat open for five months while three offers went out to people who wanted a problem he didn’t have.
He didn’t need someone who’d worked on Borg. He needed someone who’d write the runbooks, cut the alert noise, and be willing to tell a product director that the error budget was gone and the launch was moving.
That’s a different hire. It pays differently too. Quite a bit differently. This desk runs inside our wider IT staffing practice alongside the technology recruiting team, and the first thing our recruiters do on any reliability search is put a number on the target before anybody writes a job description.
A Lot of SRE Resumes Were Ops Resumes Two Quarters Ago
Around 2019 the title started paying more. Markets did what markets do. Sysadmins became SREs. Build engineers became SREs. Perfectly good infrastructure people who’d never once been woken up by a page became SREs, usually because someone in HR retitled a whole team in a single afternoon.
None of that makes them bad engineers. It does make the resume useless as a filter. Completely useless, actually.
So our recruiters stopped reading the title line. It tells you nothing now. What we ask instead is narrow and it’s very hard to fake. Which service did you own an SLO for, and what was the number? Who had the authority to stop a deploy when the budget burned down, and did anyone ever actually use it? What paged you at 3am most often last year, and what did you change so it stopped?
Somebody who lived it answers in about ninety seconds, with a service name and a percentage attached, and usually with an unprompted aside about the one dependency that kept blowing the budget every quarter. Somebody who sat next to it gives you a tour of their tooling instead. Prometheus, Grafana, Datadog, PagerDuty, Terraform, all named correctly, none of it an answer to the question that was asked. The tell is consistent enough that we screen for it on every search, and the SRE interview questions we hand hiring teams are built around the same idea. For the full role scope, the skills matrix and engagement timelines, our site reliability engineer staffing page covers the job itself in depth, and the pipeline and release side of the discipline sits with our DevOps recruiters.
Every Nine You Add Costs Roughly Ten Times the Last One
Availability targets are cheap to say. They’re expensive to mean. Here’s what each one actually buys you in downtime per 30-day month, and orange is the part you’re allowed to spend. Pick the wrong row and you either overpay by 60K or you under-hire and find out during an outage.
Hire the generalist
One strong infrastructure engineer with real on-call scars will get you here. Runbooks, sane alerting, a deploy pipeline that rolls back. Buying a specialist at this tier is money set on fire. Don’t.
Hire the SLO owner
Twenty-one minutes a month means someone has to define what “down” means and defend it in a room full of people who’d rather ship. That’s a personality, not a skill set.
Hire the systems engineer
Four minutes. That buys multi-region failover, load-shedding, and someone who writes production code. This pool is small and it prices accordingly, roughly 25 to 40% above a standard platform band.
Ask whether you mean it
Twenty-six seconds a month, and that figure has to absorb your cloud provider’s own regional incidents, your certificate renewals, and every deploy you make, none of which you fully control. Most teams asking for five nines want four and haven’t run the numbers. We’ll run them with you before we start sourcing.
Reliability Offers Rarely Die Over Money. They Die Over the Rotation.
We lost a search in week seven once, at final stage, on a candidate everybody wanted. Comp was agreed. Start date was agreed. Then he asked how many people were in the rotation and the hiring manager said two, and the call ended politely and that was the end of it.
Fair enough, honestly. A two-person rotation is a resignation with a delay built in. He was right to walk.
Good SREs have been burned before. They interview you harder than you interview them. How many people carry the pager. How many pages fire in a normal week and how many of those were actionable. Whether the team that gets woken up is allowed to spend real sprint time fixing the thing that woke them. Whether on-call is compensated, and how. Google’s Site Reliability Engineering book put a rough ceiling of 50% on operational load for a reason, and candidates at this level know the number.
Our recruiters get those answers from you first, before a single resume goes out, and we’ll say plainly if the rotation is going to lose you the hire. That conversation is uncomfortable for maybe five minutes. Losing a finalist in week seven costs a quarter. Easy trade.
Four Different Jobs, All Posted as “SRE”
These pools barely overlap. An observability specialist and a resilience engineer can both be genuinely excellent, and neither one will do the other’s job particularly well, which is exactly why the title printed on the req matters far less than the seat sitting underneath it.
Platform & Infrastructure SRE
Kubernetes, Terraform, service meshes, and the paved road other teams build on. Closest neighbour to platform engineer staffing. Deepest pool of the four.
Observability Engineer
Metrics, traces, structured logs, and the unglamorous work of deleting alerts nobody acts on. Overlaps with AIOps engineer staffing when the alerting layer gets model-driven.
Resilience & Incident Engineering
Failure injection, game days, blameless postmortems, and capacity work before peak. Often lives next to Kubernetes engineer staffing in container-heavy shops.
SRE Lead or Reliability Manager
Owns the error budget policy and the political capital to enforce it. Rarest of the four by a distance. Usually the right first hire when reliability is a program rather than a task, which platform engineering staffing covers from the team-build angle.
The Same Title Is Two Different Salaries Four Hours Apart
SRE comp doesn’t track the job title. It tracks three other things. The availability target you’re actually holding, whether the role writes production code or operates someone else’s, and the metro.
A four-nines SRE writing Go against a multi-region control plane in Seattle and an infrastructure engineer keeping a three-nines platform healthy in Irvine are separated by a wide margin, and the market moves both of them independently. The U.S. Bureau of Labor Statistics projects software development employment growing much faster than the average occupation through the decade. The subset that has genuinely run a production error budget is not growing at anything like that rate.
Remote helps. It’s the main reason a Denver or Austin search still closes. It also flattens your band, because you’re now bidding against every company that decided the same thing.
You’ll get a real number from us on the first call, set against your target and your metro, and if the band you walked in with is going to lose we’ll tell you then rather than in week six. Our 2026 site reliability engineer salary guide has the published ranges if you want to check our maths. Where the seat really sits decides which desk runs it. Infrastructure-heavy searches go to our cloud recruiters. A reliability mandate that shows up bolted to a compliance one goes to DevSecOps recruiters. And when the role is honestly a backend hire with a pager attached, software engineer recruiters own it.
What Happens After You Brief an SRE Recruiter
Same five moves whether it’s a first reliability hire or a squad of six. Depth changes. Order doesn’t.
- 01
Nines Calibration
The availability target, what “down” means to your customers, and whether anything contractual is riding on it. Thirty minutes here changes the whole shortlist. It moves the band too. Usually downward.
- 02
Bench Activation
Outreach starts with engineers our recruiters have already spoken to, not a fresh scrape. Reliability people move quietly and rarely apply, so the warm bench does most of the work here.
- 03
Incident-Ownership Screen
One real incident, walked end to end. What paged, what they tried, what was wrong, and what shipped afterwards so it wouldn’t happen again. You get notes your platform lead can read in ninety seconds.
- 04
Rotation and Comp Alignment
Rotation size, page volume, on-call pay and toil budget confirmed with you before candidates see the role. This step saves searches. Skip it and you’ll relearn why at final stage.
- 05
Offer and 90-Day Check-Ins
We run the offer conversation and check back at 30, 60 and 90 days. That habit is most of the reason 92% of our placements are still there at a year.
Three Ways to Bring Reliability Talent In
Same recruiters. Same bench. Same screen. Pick the shape that matches where the reliability program is right now.
Direct Hire
For the person who’ll still own the error budget in three years. Fee on start date, and the 90-day check-ins run either way.
Direct Hire details →Contract & Contract-to-Hire
Migration crunches, a peak season you have to survive, or pager coverage while a permanent search runs. Common when the work is real and the headcount hasn’t cleared finance yet.
Contract Staffing →Project Team
A small crew, one deliverable. Usually an observability rebuild, a multi-region move, or a reliability program that needs to exist before a compliance date.
Project Staffing →Common Questions
How do you tell a real SRE from an ops engineer with a new title?
We screen on ownership, not tooling. Which service they held an SLO for, what the number was, who could stop a deploy when the error budget burned down, and what paged them most often last year.
An engineer who lived it answers in about ninety seconds with a service name and a percentage. Everyone else answers with a tool list. Both might be strong hires. Only one can walk into a reliability mandate and start on day one.
We’re targeting 99.9%. Do we really need someone out of a hyperscaler?
Usually not. 99.9% is 43 minutes of downtime per 30-day month, and a strong infrastructure engineer with genuine on-call history will hold that comfortably with good runbooks and honest alerting.
Hyperscaler experience starts earning its premium around four nines, when multi-region failover and load-shedding stop being theoretical. Amazon’s own EC2 service level agreement commits to 99.99% only for instances spread across two or more Availability Zones, and to 99.5% for a single instance, so four nines is an architecture problem before it is a hiring problem. Below that you’re often paying 25 to 40% extra for a skill set the environment can’t use, and the hire gets bored by month eight. We’ve watched that one play out more than once. Twice this year.
Where do SREs actually come from, if almost nobody applies?
Four pools, mostly. Backend engineers who drifted into infrastructure, platform and DevOps engineers moving up the reliability ladder, network and systems people from large-scale operations, and existing SREs quietly unhappy with their rotation.
That last group is the one worth knowing about. It’s where the good ones are. A good SRE almost never posts a resume, but a bad quarter of pages will absolutely make them take a call from a recruiter they already know. Timing beats outreach volume here, which is why the bench matters more than the sourcing tool.
Is an SRE search retained or contingency?
Both work. Contingency fits most individual SRE and platform hires. Retained or engaged search fits reliability leadership, a first-in-the-company hire, or a confidential replacement where the current owner doesn’t know yet.
Volume decides the rest. If you’re standing up a rotation and need four people in a quarter, an engaged model tends to beat contingency because the recruiter can plan the sourcing sequence instead of racing. Our tech recruiters page lays out how the technology desks are structured across engagement types.
Can you find someone who has actually enforced an error budget policy?
Yes, and it’s worth asking for specifically, because the population is much smaller than the population of people who can define an SLO. Defining one is a whiteboard exercise. Enforcing one means telling a product leader no. Out loud.
We ask candidates for a time they froze or delayed a release, who pushed back, and what happened next. Some of the best answers end with the engineer losing the argument. That’s fine. What matters is that a policy existed, it had teeth, and they were the person holding it.
This is our first reliability hire. Who should we bring in first?
Hire the person who can build the practice, not the person with the deepest single tool. That usually means a senior IC who has stood up SLOs and an on-call rotation before, not a manager or a specialist.
Sequencing after that depends on what’s loudest. Follow the pain. Alert fatigue means an observability hire next. Repeated capacity incidents point to a resilience engineer. Once the rotation crosses about five people and the postmortems start stacking up faster than anyone can action them, that’s typically the point where a dedicated reliability lead starts paying for themselves.
Do you place SREs into regulated or high-compliance environments?
Regularly. Healthcare, financial services and public sector work each add change-control, audit evidence and access constraints on top of the normal reliability job, and those constraints change who’s a fit.
An engineer used to shipping twelve times a day sometimes stalls badly in an environment with a change advisory board, and it’s better to surface that in the screen than in month two. When the mandate arrives with a security requirement attached, we run it jointly with our cloud security recruiters and MLOps recruiters desks depending on the workload.
Tell us your availability target. We’ll tell you who you actually need to hire.
One call is usually enough to size the nines, the rotation, and a comp band that will hold to offer.
