• Skilled in DevSecOps principles and familiarity with CI/CD pipelines (GitHub Actions, Argo CD, Azure DevOps) to perform automated security testing.
• Experience deploying and customizing security tools to address threats and lower risk, including vulnerability scanners, static analyzers, web application firewalls (WAFs), intrusion detection/prevention systems (IDS/IPS), and endpoint security monitoring.
• A comprehensive grasp of cloud and network security, including an in‑depth understanding of Kubernetes.
• Experience in GCP specifically with one or more of the following services: Security Command Center, GKE, Cloud IDS, Cloud Armor, and Secrets Manager.
• Experience in Azure specifically with one or more of the following services: Security Center, Azure PaaS App Services, VMs, Azure SQL, Front Door, and Key Vault.
