• Strong proficiency with Infrastructure as Code, particularly Terraform or Ansible
• Hands‑on experience with CI/CD tools such as Jenkins, GitLab CI, or GitHub Actions
• Demonstrated experience performing vulnerability assessments, security audits, risk analysis, and remediation, including patch management
