Key Skills

What to Include on a Platform Engineer Resume

• A concise summary that states your platform engineer experience level, strongest domain, and the business problems you solve.
• A skills section that mirrors the job description language for Kubernetes, Backstage, Crossplane, Go.
• Experience bullets that connect platform engineer, internal developer platform, developer experience to measurable outcomes such as cost savings, faster delivery, better quality, or improved customer results.
• Tools, platforms, certifications, and methods that are current for devops & cloud roles.
• Recent projects that show ownership, cross-functional work, and a clear result instead of generic responsibilities.

Sample Experience Bullets

• Built the internal developer platform on Backstage for 300+ engineers, providing service catalog, documentation, and self-service infrastructure provisioning through a unified portal. Service onboarding time dropped from 2 weeks of tickets and meetings to about 2 hours
• Designed self-service Kubernetes namespace provisioning with Crossplane that handles resource quotas, network policies, and service mesh configuration automatically when a team requests a new environment. Teams can deploy new services to staging in under 10 minutes
• Created golden path templates for 5 common service types including REST APIs, async workers, cron jobs, event consumers, and static frontends with pre-configured CI/CD, monitoring, and logging. Template adoption reached 80% across the org and first deploys happen 3x faster
• Assembled a unified observability stack integrating Prometheus metrics, Loki logs, and Tempo traces with consistent correlation IDs across all layers. Mean time to detection dropped 65% because engineers can now jump from an alert to the relevant logs and traces in seconds
• Added automated security scanning to the deployment pipeline using Trivy for container images and Checkov for infrastructure code, blocking any deployment with critical findings. The pipeline catches about 200 vulnerabilities per quarter before they reach production
• Owned the Kubernetes platform that runs all production workloads across 3 clusters, handling version upgrades, node pool management, and capacity planning on a monthly cadence. Cluster availability stayed at 99.97% over the past year including during 4 major version upgrades
• Wrote comprehensive platform documentation and held weekly office hours to help developers use the platform effectively, answering about 20 support requests per week ranging from deployment issues to configuration questions. Documentation satisfaction scores averaged 4.3 out of 5
• Worked with the SRE team to define SLOs for platform reliability including deployment pipeline uptime, build queue wait times, and namespace provisioning latency. Committed to 99.95% uptime for the deployment pipeline and consistently met the target over 4 quarters
• Built a CLI tool in Go that developers use to scaffold new services, manage environment configs, run local development environments, and deploy to staging with a single command. The tool has 250+ daily active users and handles about 1,000 commands per day
• Implemented a secrets management solution using HashiCorp Vault with Kubernetes integration that automatically injects secrets into pods at runtime, replacing a previous approach where teams stored secrets in config maps. The migration covered 100+ services over 6 weeks
• Created a cost allocation system that tracks Kubernetes resource usage by team and service, generating monthly reports that show actual consumption versus requested resources. The visibility helped teams right-size their deployments and reduced overall cluster costs by 30%
