Common Mistakes on Junior Platform Engineer Resumes

  • Overclaiming Kubernetes expertise - Be honest about your depth. 'Maintained EKS clusters' is credible. 'Architected multi-cluster federation' is not for a junior.
  • No automation metrics - Time saved, setup time reduced, and manual tasks eliminated are the core value propositions of platform work.
  • Hiding the internship - Infrastructure internship experience is directly relevant. Include it with strong, quantified bullets.
  • Listing every cloud service you have seen - Focus on the 5-8 AWS services you have actually used. Padding your skills list invites tough interview questions.
  • Missing monitoring and alerting experience - Prometheus, Grafana, and CloudWatch experience shows you understand operational responsibility, not just provisioning.
