How to write yours — DevOps Engineer tips
- Replace vague praise with quantified results: cite actual metrics (e.g., '40% reduction in deployment time', '99.99% uptime') rather than describing yourself as 'experienced' or 'skilled'
- Name 3-4 specific tools/technologies (Kubernetes, Terraform, Prometheus, Jenkins, AWS/Azure) that appear in the job description and explain what you shipped with them
- Show you understand DevOps philosophy by mentioning Infrastructure-as-Code, monitoring strategy, or CI/CD culture—not just tool proficiency
- Include a concrete incident or project where you solved a real problem (e.g., migration, cost optimization, performance tuning) with measurable impact
- Reference the company's actual tech challenges or scale (from their blog, job posting, or public engineering) to prove you've done research and aren't using a template
