The fastest way to identify an SRE CV that will be rejected is the absence of three words: SLO, error budget, and toil. These are not jargon to drop in for effect — they are the defining concepts of the Site Reliability Engineering discipline, and hiring managers for SRE roles use them as filters before they read anything else. A CV that describes operations work and infrastructure management without these concepts reads as a DevOps engineer who has been given an SRE title, not someone who practises reliability engineering as Google defined it. The second filter is coding evidence. The Google SRE model explicitly requires that SREs spend at least 50% of their time on software engineering — writing code that automates operations and eliminates toil. An SRE CV without automation, tooling, or internal software evidence fails this test. This guide covers how to position an SRE CV around the right language, the ATS keywords that work, and the bullet patterns that demonstrate reliability engineering rather than operational management.

What Site Reliability Engineer Job Descriptions Require in 2026

SRE roles in 2026 JDs cluster around two models: the Google-model SRE (strong software engineering background, 50/50 coding/operations split, writes automation in Python or Go) and the enterprise SRE (predominantly operations with scripting, responsible for SLA management and incident coordination). Most companies that hire SREs by title intend the former but often end up with the latter in practice.

Requirements that appear consistently across SRE job descriptions:

  • Service Level Objectives and error budgets — defining and owning SLOs for production services, monitoring error budget burn rate, and making engineering prioritisation decisions based on budget data. This is the definitional skill of the role. JDs list it as "experience with SLO-based reliability engineering" or "error budget management."
  • Production software engineering — writing automation in Python or Go that eliminates manual operational work. SRE JDs explicitly require coding; many state "software engineering experience" as a primary requirement alongside operations skills.
  • Incident response and blameless post-mortems — on-call rotation experience, incident command, and the ability to run blameless post-mortems that produce systemic fixes rather than individual blame. Most JDs include "lead post-mortems" as an explicit bullet.
  • Observability and distributed tracing — Prometheus, Grafana, Datadog for metrics; OpenTelemetry and Jaeger or Zipkin for distributed tracing across microservices. SREs are expected to instrument systems, not just watch dashboards.
  • Capacity planning and load testing — projecting infrastructure needs, running load tests with k6, Locust, or JMeter, and managing scaling events before they become incidents.
  • Kubernetes at operational depth — not just deploying on k8s but managing cluster health, understanding resource contention, diagnosing OOMKills and CrashLoopBackOffs in production.

SRE salaries in 2026: £55K–£95K UK; $120K–$185K US, with senior SREs at Google, Meta, and equivalent-scale companies exceeding $220K total compensation.

ATS Keywords for a Site Reliability Engineer CV

SRE roles have more varied ATS terminology than most engineering disciplines. The same role is posted as: Site Reliability Engineer, SRE, Production Engineer (Meta), Platform Reliability Engineer, Infrastructure Engineer (SRE focus), or Reliability Engineer. All respond to similar keyword clusters.

Essential ATS terms for an SRE CV:

  • Title variants: Site Reliability Engineer, SRE, Production Engineer, Platform Reliability Engineer, Infrastructure Engineer
  • Reliability concepts: SLO, SLA, SLI, error budget, reliability engineering, toil reduction, chaos engineering, fault injection
  • Languages: Python, Go, Bash; sometimes Java or Kotlin for JVM-stack companies
  • Orchestration: Kubernetes, Helm, Docker, EKS, GKE, AKS, container orchestration
  • Observability stack: Prometheus, Grafana, Alertmanager, Datadog, OpenTelemetry, Jaeger, Zipkin, ELK, Loki, PagerDuty, VictorOps
  • IaC: Terraform, Ansible, Pulumi
  • Load and chaos testing: k6, Locust, Chaos Monkey, Gremlin, Litmus
  • Long-tail phrases: site reliability engineer resume examples, how to write an SRE resume, SRE cv template, site reliability engineer skills for resume

Placement: "SRE" or "Site Reliability Engineer" in your headline, plus your primary language (Python or Go) and observability stack. In your Skills section, add a separate "Reliability Practices" category with SLO, error budget, and incident response explicitly listed — this is the keyword cluster that distinguishes your CV from a DevOps engineer's.

SRE CV Structure and Bullets That Demonstrate Reliability Engineering

Section order:

  1. Headline — "Site Reliability Engineer | Python · Kubernetes · Prometheus · SLO Management"
  2. Skills — layered: Languages / Orchestration / Observability / IaC / Reliability Practices
  3. Experience — 4–6 bullets per role; SLO ownership, MTTR, toil metrics here
  4. Certifications — CKA, AWS Solutions Architect, GCP Professional Cloud Architect; important for ATS screening
  5. Education — bottom of page; CS degree valued more in SRE than in DevOps due to software engineering component

Two pages for 4+ years; one to two pages for under 4. GitHub link matters for SRE roles that involve tooling development — include it.

The three metrics that characterise strong SRE bullet points: reliability outcome (uptime, MTTR, incident reduction), coding/automation evidence (tool written, hours of toil eliminated), and process impact (post-mortem improvements, SLO framework established). Three examples:

  • Defined and owned SLOs for 12 production services across 3 engineering teams; implemented error budget policy that triggered reliability sprint work when burn rate exceeded 2x target, reducing P0 incidents by 60% over 2 quarters
  • Built a canary analysis automation tool in Go that replaced 4 hours of daily manual deployment verification with a 3-minute automated comparison against baseline metrics, saving approximately 800 engineering hours per year across the SRE team
  • Led post-mortem for a 4-hour multi-region database outage affecting 300K users — facilitated blameless analysis, identified 3 contributing system causes, and drove an 8-week reliability project reducing recurrence probability by 85%

SRE technical interviews differ significantly from DevOps interviews. Expect: systems design for high availability ("design a payment processing system with 99.99% uptime requirements"), a coding exercise in Python or Go (typically a monitoring or automation tool), and a deep post-mortem discussion where interviewers probe your incident analysis thinking. Scale of the system you describe in interview is calibrated from your CV — reliability metrics and service scale in your bullets set the level of the design question you receive.

Three SRE CV Mistakes That Get You Screened as DevOps Instead

No SLO, error budget, or toil language. These three concepts define the SRE discipline. Their absence from a CV is the primary reason experienced operations engineers with real reliability work get screened as DevOps candidates rather than SRE candidates. Error budget management — having defined the policy, owned the decision to halt feature work when the budget was exhausted, and reported on reliability posture to engineering leadership — belongs explicitly in at least one bullet point. If you have done this work, name it precisely.

On-call listed as a duty, not as a performance metric. "Member of on-call rotation" is background noise in an SRE CV. "Primary on-call for 8 production services over 18 months, handling 23 P1 incidents with average MTTR of 18 minutes; produced 23 blameless post-mortems with 100% action item completion rate, reducing similar incident frequency by 45%" is what differentiates SRE-quality incident ownership from being on a rota.

No code evidence. Google's definition of SRE requires at minimum 50% software engineering time. Senior SRE hiring managers test this directly in interview — they will ask candidates to walk through code they wrote for automation or tooling. A CV with no GitHub link, no described automation tools, and no programming language in the Skills section reads as an operations engineer with an SRE title. If you have written Python scripts for automation, built monitoring dashboards with custom alerting logic, or developed internal tooling — each of these belongs in the CV as a bullet, not left out because "it was just scripts."
