How to Become a Site Reliability Engineer

SREs keep production healthy through SLOs, observability and incident response, and they write software to remove toil. Day to day, the work splits between building new capability and keeping existing systems trustworthy — the ratio shifts toward the latter as a company matures.

Interviews for these roles are usually four to six stages: recruiter screen, a technical screen on Kubernetes or Observability, a deeper practical or design round, and a hiring-manager conversation about scope and ownership.

Months 1–4: get fluent in Kubernetes and Observability. Build two projects that you could explain end to end in an interview, including what you'd change under load.

Months 5–8: add Go and Incident Response. Start reading real job descriptions weekly and note the vocabulary gaps between them and your resume.

Months 9–12: apply in volume within the first 72 hours of a posting going live, tailor each resume to the posting's exact terms, and run every version through an ATS check before submitting.
