Security Engineer Resume Example
Updated September 2026
Hiring teams look for security engineers who bridge the gap between software development and infrastructure defense rather than just filing tickets. Frame your background around what you built or automated, whether that is hardening AWS IAM roles, writing custom Semgrep rules, or speeding up vulnerability remediation SLA times. Mention your primary tech stack early so technical screeners know whether you lean toward AppSec, cloud infrastructure, or detection engineering.
What to Write on Your Security Engineer Resume
Use quantified achievement bullets instead of generic duties. Here are examples tailored for security engineer roles:
- 1Engineered automated SAST scanning across 45 GitHub repositories using Semgrep and GitHub Actions, blocking 120+ high-severity vulnerabilities prior to production and cutting developer security ticket backlog by 65%.
- 2Hardened AWS multi-account infrastructure for 80 microservices by enforcing least-privilege IAM policies, removing 400+ wildcard permissions and reducing cloud security misconfigurations by 78% in Wiz.
- 3Authored 35 custom detection rules in Panther and Splunk mapped to MITRE ATT&CK techniques, slashing mean time to detect (MTTD) from 4 hours to 11 minutes across 1,200 production endpoints.
- 4Constructed an automated secret-scanning workflow using Trufflehog and HashiCorp Vault, eliminating hardcoded credentials in codebase commits and remediating 94 exposed API tokens within 24 hours.
